   * This module currently provides iterative methods to solve problems of the form \c A \c x = \c b, where \c A is a squared matrix, usually very large and sparse.
   * Those solvers are accessible via the following classes:
   *  - ConjugateGradient for selfadjoint (hermitian) matrices,
+  *  - LeastSquaresConjugateGradient for rectangular least-square problems,
   *  - BiCGSTAB for general square matrices.
   *
   * These iterative solvers are associated with some preconditioners:
   *  - IdentityPreconditioner - not really useful
-  *  - DiagonalPreconditioner - also called JAcobi preconditioner, work very well on diagonal dominant matrices.
-  *  - IncompleteILUT - incomplete LU factorization with dual thresholding
+  *  - DiagonalPreconditioner - also called Jacobi preconditioner, work very well on diagonal dominant matrices.
+  *  - IncompleteLUT - incomplete LU factorization with dual thresholding
   *
   * Such problems can also be solved using the direct sparse decomposition modules: SparseCholesky, CholmodSupport, UmfPackSupport, SuperLUSupport.

-  * \param T the numeric type at hand
+  * \tparam T the numeric type at hand
   *
   * This class stores enums, typedefs and static methods giving information about a numeric type.
   *
   * The provided data consists of:
-  * \li A typedef \a Real, giving the "real part" type of \a T. If \a T is already real,
-  *     then \a Real is just a typedef to \a T. If \a T is \c std::complex<U> then \a Real
+  * \li A typedef \c Real, giving the "real part" type of \a T. If \a T is already real,
+  *     then \c Real is just a typedef to \a T. If \a T is \c std::complex<U> then \c Real
   *     is a typedef to \a U.
-  * \li A typedef \a NonInteger, giving the type that should be used for operations producing non-integral values,
+  * \li A typedef \c NonInteger, giving the type that should be used for operations producing non-integral values,
   *     such as quotients, square roots, etc. If \a T is a floating-point type, then this typedef just gives
   *     \a T again. Note however that many Eigen functions such as internal::sqrt simply refuse to
   *     take integers. Outside of a few cases, Eigen doesn't do automatic type promotion. Thus, this typedef is
   *     only intended as a helper for code that needs to explicitly promote types.
+  * \li A typedef \c Literal giving the type to use for numeric literals such as "2" or "0.5". For instance, for \c std::complex<U>, Literal is defined as \c U.
+  *     Of course, this type must be fully compatible with \a T. In doubt, just use \a T here.
   * \li A typedef \a Nested giving the type to use to nest a value inside of the expression tree. If you don't know what
   *     this means, just use \a T here.
   * \li An enum value \a IsComplex. It is equal to 1 if \a T is a \c std::complex
@@ -42,10 +75,14 @@ namespace Eigen {
   * \li An enum value \a IsSigned. It is equal to \c 1 if \a T is a signed type and to 0 if \a T is unsigned.
   * \li An enum value \a RequireInitialization. It is equal to \c 1 if the constructor of the numeric type \a T must
   *     be called, and to 0 if it is safe not to call it. Default is 0 if \a T is an arithmetic type, and 1 otherwise.
-  * \li An epsilon() function which, unlike std::numeric_limits::epsilon(), returns a \a Real instead of a \a T.
+  * \li An epsilon() function which, unlike <a href="http://en.cppreference.com/w/cpp/types/numeric_limits/epsilon">std::numeric_limits::epsilon()</a>,
+  *     it returns a \a Real instead of a \a T.
   * \li A dummy_precision() function returning a weak epsilon value. It is mainly used as a default
   *     value by the fuzzy comparison operators.
   * \li highest() and lowest() functions returning the highest and lowest possible values respectively.
+  * \li digits10() function returning the number of decimal digits that can be represented without change. This is
+  *     the analogue of <a href="http://en.cppreference.com/w/cpp/types/numeric_limits/digits10">std::numeric_limits<T>::digits10</a>

-/** \class Ref
-  * \ingroup Core_Module
-  *
-  * \brief A matrix or vector expression mapping an existing expressions
-  *
-  * \tparam PlainObjectType the equivalent matrix type of the mapped data
-  * \tparam Options specifies whether the pointer is \c #Aligned, or \c #Unaligned.
-  *                The default is \c #Unaligned.
-  * \tparam StrideType optionally specifies strides. By default, Ref implies a contiguous storage along the inner dimension (inner stride==1),
-  *                   but accept a variable outer stride (leading dimension).
-  *                   This can be overridden by specifying strides.
-  *                   The type passed here must be a specialization of the Stride template, see examples below.
-  *
-  * This class permits to write non template functions taking Eigen's object as parameters while limiting the number of copies.
-  * A Ref<> object can represent either a const expression or a l-value:
-  * \code
-  * // in-out argument:
-  * void foo1(Ref<VectorXf> x);
-  *
-  * // read-only const argument:
-  * void foo2(const Ref<const VectorXf>& x);
-  * \endcode
-  *
-  * In the in-out case, the input argument must satisfies the constraints of the actual Ref<> type, otherwise a compilation issue will be triggered.
-  * By default, a Ref<VectorXf> can reference any dense vector expression of float having a contiguous memory layout.
-  * Likewise, a Ref<MatrixXf> can reference any column major dense matrix expression of float whose column's elements are contiguously stored with
-  * the possibility to have a constant space inbetween each column, i.e.: the inner stride mmust be equal to 1, but the outer-stride (or leading dimension),
-  * can be greater than the number of rows.
-  *
-  * In the const case, if the input expression does not match the above requirement, then it is evaluated into a temporary before being passed to the function.
-  * Here are some examples:
-  * \code
-  * MatrixXf A;
-  * VectorXf a;
-  * foo1(a.head());             // OK
-  * foo1(A.col());              // OK
-  * foo1(A.row());              // compilation error because here innerstride!=1
-  * foo2(A.row());              // The row is copied into a contiguous temporary
-  * foo2(2*a);                  // The expression is evaluated into a temporary
-  * foo2(A.col().segment(2,4)); // No temporary
-  * \endcode
-  *
-  * The range of inputs that can be referenced without temporary can be enlarged using the last two template parameter.
-  * Here is an example accepting an innerstride!=1:
-  * \code
-  * // in-out argument:
-  * void foo3(Ref<VectorXf,0,InnerStride<> > x);
-  * foo3(A.row());              // OK
-  * \endcode
-  * The downside here is that the function foo3 might be significantly slower than foo1 because it won't be able to exploit vectorization, and will involved more
-  * expensive address computations even if the input is contiguously stored in memory. To overcome this issue, one might propose to overloads internally calling a
-  * template function, e.g.:
-  * \code
-  * // in the .h:
-  * void foo(const Ref<MatrixXf>& A);
-  * void foo(const Ref<MatrixXf,0,Stride<> >& A);
-  *
-  * // in the .cpp:
-  * template<typename TypeOfA> void foo_impl(const TypeOfA& A) {
-  *     ... // crazy code goes here
-  * }
-  * void foo(const Ref<MatrixXf>& A) { foo_impl(A); }
-  * void foo(const Ref<MatrixXf,0,Stride<> >& A) { foo_impl(A); }
-  * \endcode

+/** \class ScalarBinaryOpTraits
+  * \ingroup Core_Module
+  *
+  * \brief Determines whether the given binary operation of two numeric types is allowed and what the scalar return type is.
+  *
+  * This class permits to control the scalar return type of any binary operation performed on two different scalar types through (partial) template specializations.
+  *
+  * For instance, let \c U1, \c U2 and \c U3 be three user defined scalar types for which most operations between instances of \c U1 and \c U2 returns an \c U3.
+  * You can let %Eigen knows that by defining:
+    \code
+    template<typename BinaryOp>
+    struct ScalarBinaryOpTraits<U1,U2,BinaryOp> { typedef U3 ReturnType;  };
+    template<typename BinaryOp>
+    struct ScalarBinaryOpTraits<U2,U1,BinaryOp> { typedef U3 ReturnType;  };
+    \endcode
+  * You can then explicitly disable some particular operations to get more explicit error messages:
+    \code
+    template<>
+    struct ScalarBinaryOpTraits<U1,U2,internal::scalar_max_op<U1,U2> > {};
+    \endcode
+  * Or customize the return type for individual operation:
+    \code
+    template<>
+    struct ScalarBinaryOpTraits<U1,U2,internal::scalar_sum_op<U1,U2> > { typedef U1 ReturnType; };
+    \endcode
+  *
+  * By default, the following generic combinations are supported:
+  <table class="manual">
+  <tr><th>ScalarA</th><th>ScalarB</th><th>BinaryOp</th><th>ReturnType</th><th>Note</th></tr>
+  <tr            ><td>\c T </td><td>\c T </td><td>\c * </td><td>\c T </td><td></td></tr>
+  <tr class="alt"><td>\c NumTraits<T>::Real </td><td>\c T </td><td>\c * </td><td>\c T </td><td>Only if \c NumTraits<T>::IsComplex </td></tr>
+  <tr            ><td>\c T </td><td>\c NumTraits<T>::Real </td><td>\c * </td><td>\c T </td><td>Only if \c NumTraits<T>::IsComplex </td></tr>

-  * \brief A hyperplane
-  *
-  * A hyperplane is an affine subspace of dimension n-1 in a space of dimension n.
-  * For example, a hyperplane in a plane is a line; a hyperplane in 3-space is a plane.
-  *
-  * \param _Scalar the scalar type, i.e., the type of the coefficients
-  * \param _AmbientDim the dimension of the ambient space, can be a compile time value or Dynamic.
-  *             Notice that the dimension of the hyperplane is _AmbientDim-1.
-  *
-  * This class represents an hyperplane as the zero set of the implicit equation
-  * \f$ n \cdot x + d = 0 \f$ where \f$ n \f$ is a unit normal vector of the plane (linear part)
-  * and \f$ d \f$ is the distance (offset) to the origin.

-  *
-  * \leastsquares_module
-  *
-  * For a set of points, this function tries to express
-  * one of the coords as a linear (affine) function of the other coords.
-  *
-  * This is best explained by an example. This function works in full
-  * generality, for points in a space of arbitrary dimension, and also over
-  * the complex numbers, but for this example we will work in dimension 3
-  * over the real numbers (doubles).
-  *
-  * So let us work with the following set of 5 points given by their
-  * \f$(x,y,z)\f$ coordinates:
-  * @code
-    Vector3d points[5];
-    points[0] = Vector3d( 3.02, 6.89, -4.32 );
-    points[1] = Vector3d( 2.01, 5.39, -3.79 );
-    points[2] = Vector3d( 2.41, 6.01, -4.01 );
-    points[3] = Vector3d( 2.09, 5.55, -3.86 );
-    points[4] = Vector3d( 2.58, 6.32, -4.10 );
-  * @endcode
-  * Suppose that we want to express the second coordinate (\f$y\f$) as a linear
-  * expression in \f$x\f$ and \f$z\f$, that is,
-  * \f[ y=ax+bz+c \f]
-  * for some constants \f$a,b,c\f$. Thus, we want to find the best possible
-  * constants \f$a,b,c\f$ so that the plane of equation \f$y=ax+bz+c\f$ fits
-  * best the five above points. To do that, call this function as follows:
-  * @code
-    Vector3d coeffs; // will store the coefficients a, b, c
-    linearRegression(
-      5,
-      &points,
-      &coeffs,
-      1 // the coord to express as a function of
-        // the other ones. 0 means x, 1 means y, 2 means z.
-    );
-  * @endcode
-  * Now the vector \a coeffs is approximately
-  * \f$( 0.495 ,  -1.927 ,  -2.906 )\f$.
-  * Thus, we get \f$a=0.495, b = -1.927, c = -2.906\f$. Let us check for
-  * instance how near points[0] is from the plane of equation \f$y=ax+bz+c\f$.
-  * Looking at the coords of points[0], we see that:
-  * \f[ax+bz+c = 0.495 * 3.02 + (-1.927) * (-4.32) + (-2.906) = 6.91.\f]
-  * On the other hand, we have \f$y=6.89\f$. We see that the values
-  * \f$6.91\f$ and \f$6.89\f$
-  * are near, so points[0] is very near the plane of equation \f$y=ax+bz+c\f$.
-  *
-  * Let's now describe precisely the parameters:
-  * @param numPoints the number of points
-  * @param points the array of pointers to the points on which to perform the linear regression
-  * @param result pointer to the vector in which to store the result.
-                  This vector must be of the same type and size as the
-                  data points. The meaning of its coords is as follows.
-                  For brevity, let \f$n=Size\f$,
-                  \f$r_i=result[i]\f$,
-                  and \f$f=funcOfOthers\f$. Denote by
-                  \f$x_0,\ldots,x_{n-1}\f$
-                  the n coordinates in the n-dimensional space.
-                  Then the resulting equation is:
-                  \f[ x_f = r_0 x_0 + \cdots + r_{f-1}x_{f-1}
-                   + r_{f+1}x_{f+1} + \cdots + r_{n-1}x_{n-1} + r_n. \f]
-  * @param funcOfOthers Determines which coord to express as a function of the
-                        others. Coords are numbered starting from 0, so that a
-                        value of 0 means \f$x\f$, 1 means \f$y\f$,
-                        2 means \f$z\f$, ...

-  *
-  * This function is quite similar to linearRegression(), so we refer to the
-  * documentation of this function and only list here the differences.
-  *
-  * The main difference from linearRegression() is that this function doesn't
-  * take a \a funcOfOthers argument. Instead, it finds a general equation
-  * of the form
-  * \f[ r_0 x_0 + \cdots + r_{n-1}x_{n-1} + r_n = 0, \f]
-  * where \f$n=Size\f$, \f$r_i=retCoefficients[i]\f$, and we denote by
-  * \f$x_0,\ldots,x_{n-1}\f$ the n coordinates in the n-dimensional space.
-  *
-  * Thus, the vector \a retCoefficients has size \f$n+1\f$, which is another
-  * difference from linearRegression().
-  *
-  * In practice, this function performs an hyper-plane fit in a total least square sense
-  * via the following steps:
-  *  1 - center the data to the mean
-  *  2 - compute the covariance matrix
-  *  3 - pick the eigenvector corresponding to the smallest eigenvalue of the covariance matrix
-  * The ratio of the smallest eigenvalue and the second one gives us a hint about the relevance
-  * of the solution. This value is optionally returned in \a soundness.

 /** \ingroup IterativeLinearSolvers_Module
-  * \brief A conjugate gradient solver for sparse self-adjoint problems
+  * \brief A conjugate gradient solver for sparse (or dense) self-adjoint problems
   *
-  * This class allows to solve for A.x = b sparse linear problems using a conjugate gradient algorithm.
-  * The sparse matrix A must be selfadjoint. The vectors x and b can be either dense or sparse.
+  * This class allows to solve for A.x = b linear problems using an iterative conjugate gradient algorithm.
+  * The matrix A must be selfadjoint. The matrix A and the vectors x and b can be either dense or sparse.
   *
   * \tparam _MatrixType the type of the matrix A, can be a dense or a sparse matrix.
   * \tparam _UpLo the triangular part that will be used for the computations. It can be Lower,
-  *               Upper, or Lower|Upper in which the full matrix entries will be considered. Default is Lower.
+  *               \c Upper, or \c Lower|Upper in which the full matrix entries will be considered.
+  *               Default is \c Lower, best performance is \c Lower|Upper.
   * \tparam _Preconditioner the type of the preconditioner. Default is DiagonalPreconditioner
   *
+  * \implsparsesolverconcept
+  *
   * The maximal number of iterations and tolerance value can be controlled via the setMaxIterations()
   * and setTolerance() methods. The defaults are the size of the problem for the maximal number of iterations
   * and NumTraits<Scalar>::epsilon() for the tolerance.
   * 
+  * The tolerance corresponds to the relative residual error: |Ax-b|/|b|
+  * 
+  * \b Performance: Even though the default value of \c _UpLo is \c Lower, significantly higher performance is
+  * achieved when using a complete matrix and \b Lower|Upper as the \a _UpLo template parameter. Moreover, in this
+  * case multi-threading can be exploited if the user code is compiled with OpenMP enabled.
+  * See \ref TopicMultiThreading for details.
+  * 
   * This class can be used as the direct solver classes. Here is a typical usage example:
-  * \code
-  * int n = 10000;
-  * VectorXd x(n), b(n);
-  * SparseMatrix<double> A(n,n);
-  * // fill A and b
-  * ConjugateGradient<SparseMatrix<double> > cg;
-  * cg.compute(A);
-  * x = cg.solve(b);
-  * std::cout << "#iterations:     " << cg.iterations() << std::endl;
-  * std::cout << "estimated error: " << cg.error()      << std::endl;
-  * // update b, and solve again
-  * x = cg.solve(b);
-  * \endcode
+    \code
+    int n = 10000;
+    VectorXd x(n), b(n);
+    SparseMatrix<double> A(n,n);
+    // fill A and b
+    ConjugateGradient<SparseMatrix<double>, Lower|Upper> cg;
+    cg.compute(A);
+    x = cg.solve(b);
+    std::cout << "#iterations:     " << cg.iterations() << std::endl;
+    std::cout << "estimated error: " << cg.error()      << std::endl;
+    // update b, and solve again
+    x = cg.solve(b);
+    \endcode
   * 
   * By default the iterations start with x=0 as an initial guess of the solution.
   * One can control the start using the solveWithGuess() method.
   * 
   * ConjugateGradient can also be used in a matrix-free context, see the following \link MatrixfreeSolverExample example \endlink.

+  * fill-in reducing permutation as computed by the ordering method.
+  *
+  * \b Shifting \b strategy: Let \f$ B = S P A P' S \f$  be the scaled matrix on which the factorization is carried out,
+  * and \f$ \beta \f$ be the minimum value of the diagonal. If \f$ \beta > 0 \f$ then, the factorization is directly performed
+  * on the matrix B. Otherwise, the factorization is performed on the shifted matrix \f$ B + (\sigma+|\beta| I \f$ where
+  * \f$ \sigma \f$ is the initial shift value as returned and set by setInitialShift() method. The default value is \f$ \sigma = 10^{-3} \f$.
+  * If the factorization fails, then the shift in doubled until it succeed or a maximum of ten attempts. If it still fails, as returned by

+  * The matrix A and the vectors x and b can be either dense or sparse.
+  *
+  * \tparam _MatrixType the type of the matrix A, can be a dense or a sparse matrix.
+  * \tparam _Preconditioner the type of the preconditioner. Default is LeastSquareDiagonalPreconditioner
+  *
+  * \implsparsesolverconcept
+  * 
+  * The maximal number of iterations and tolerance value can be controlled via the setMaxIterations()
+  * and setTolerance() methods. The defaults are the size of the problem for the maximal number of iterations
+  * and NumTraits<Scalar>::epsilon() for the tolerance.
+  * 
+  * This class can be used as the direct solver classes. Here is a typical usage example:
+    \code
+    int m=1000000, n = 10000;
+    VectorXd x(n), b(m);
+    SparseMatrix<double> A(m,n);
+    // fill A and b
+    LeastSquaresConjugateGradient<SparseMatrix<double> > lscg;
+    lscg.compute(A);
+    x = lscg.solve(b);
+    std::cout << "#iterations:     " << lscg.iterations() << std::endl;
+    std::cout << "estimated error: " << lscg.error()      << std::endl;
+    // update b, and solve again
+    x = lscg.solve(b);
+    \endcode
+  * 
+  * By default the iterations start with x=0 as an initial guess of the solution.
+  * One can control the start using the solveWithGuess() method.
+  *

+Installation instructions for Eigen
+***********************************
+
+Explanation before starting
+***************************
+
+Eigen consists only of header files, hence there is nothing to compile
+before you can use it. Moreover, these header files do not depend on your
+platform, they are the same for everybody.
+
+Method 1. Installing without using CMake
+****************************************
+
+You can use right away the headers in the Eigen/ subdirectory. In order
+to install, just copy this Eigen/ subdirectory to your favorite location.
+If you also want the unsupported features, copy the unsupported/
+subdirectory too.
+
+Method 2. Installing using CMake
+********************************
+
+Let's call this directory 'source_dir' (where this INSTALL file is).
+Before starting, create another directory which we will call 'build_dir'.
+
+Do:
+
+  cd build_dir
+  cmake source_dir
+  make install
+
+The "make install" step may require administrator privileges.
+
+You can adjust the installation destination (the "prefix")
+by passing the -DCMAKE_INSTALL_PREFIX=myprefix option to cmake, as is
+explained in the message that cmake prints at the end.

+This folder contains a couple of benchmark utities and Eigen benchmarks.
+
+****************************
+* bench_multi_compilers.sh *
+****************************
+
+This script allows to run a benchmark on a set of different compilers/compiler options.
+It takes two arguments:
+ - a file defining the list of the compilers with their options
+ - the .cpp file of the benchmark
+
+Examples:

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.

+Bench Template Library
+
+****************************************
+Introduction :
+
+The aim of this project is to compare the performance
+of available numerical libraries. The code is designed
+as generic and modular as possible. Thus, adding new
+numerical libraries or new numerical tests should
+require minimal effort.
+
+
+*****************************************
+
+Installation :
+
+BTL uses cmake / ctest:
+
+1 - create a build directory:
+
+  $ mkdir build
+  $ cd build
+
+2 - configure:
+
+  $ ccmake ..
+
+3 - run the bench using ctest:
+
+  $ ctest -V
+
+You can run the benchmarks only on libraries matching a given regular expression:
+  ctest -V -R <regexp>
+For instance:
+  ctest -V -R eigen2
+
+You can also select a given set of actions defining the environment variable BTL_CONFIG this way:
+  BTL_CONFIG="-a action1{:action2}*" ctest -V
+An exemple:
+  BTL_CONFIG="-a axpy:vector_matrix:trisolve:ata" ctest -V -R eigen2
+
+Finally, if bench results already exist (the bench*.dat files) then they merges by keeping the best for each matrix size. If you want to overwrite the previous ones you can simply add the "--overwrite" option:
+  BTL_CONFIG="-a axpy:vector_matrix:trisolve:ata --overwrite" ctest -V -R eigen2
+
+4 : Analyze the result. different data files (.dat) are produced in each libs directories.
+ If gnuplot is available, choose a directory name in the data directory to store the results and type:
+        $ cd data
+        $ mkdir my_directory
+        $ cp ../libs/*/*.dat my_directory
+ Build the data utilities in this (data) directory
+        make
+ Then you can look the raw data,
+        go_mean my_directory
+ or smooth the data first :
+	smooth_all.sh my_directory
+	go_mean my_directory_smooth
+
+
+*************************************************
+
+Files and directories :
+
+ generic_bench : all the bench sources common to all libraries
+
+ actions : sources for different action wrappers (axpy, matrix-matrix product) to be tested.
+
+ libs/* : bench sources specific to each tested libraries.
+
+ machine_dep : directory used to store machine specific Makefile.in
+
+ data : directory used to store gnuplot scripts and data analysis utilities
+
+**************************************************
+
+Principles : the code modularity is achieved by defining two concepts :
+
+ ****** Action concept : This is a class defining which kind
+  of test must be performed (e.g. a matrix_vector_product).
+	An Action should define the following methods :
+
+        *** Ctor using the size of the problem (matrix or vector size) as an argument
+	    Action action(size);
+        *** initialize : this method initialize the calculation (e.g. initialize the matrices and vectors arguments)
+	    action.initialize();
+	*** calculate : this method actually launch the calculation to be benchmarked
+	    action.calculate;
+	*** nb_op_base() : this method returns the complexity of the calculate method (allowing the mflops evaluation)
+        *** name() : this method returns the name of the action (std::string)
+
+ ****** Interface concept : This is a class or namespace defining how to use a given library and
+  its specific containers (matrix and vector). Up to now an interface should following types
+
+	*** real_type : kind of float to be used (float or double)
+	*** stl_vector : must correspond to std::vector<real_type>
+	*** stl_matrix : must correspond to std::vector<stl_vector>
+	*** gene_vector : the vector type for this interface        --> e.g. (real_type *) for the C_interface
+	*** gene_matrix : the matrix type for this interface        --> e.g. (gene_vector *) for the C_interface
+
+	+ the following common methods
+
+        *** free_matrix(gene_matrix & A, int N)  dealocation of a N sized gene_matrix A
+        *** free_vector(gene_vector & B)  dealocation of a N sized gene_vector B
+        *** matrix_from_stl(gene_matrix & A, stl_matrix & A_stl) copy the content of an stl_matrix A_stl into a gene_matrix A.
+	     The allocation of A is done in this function.
+	*** vector_to_stl(gene_vector & B, stl_vector & B_stl)  copy the content of an stl_vector B_stl into a gene_vector B.
+	     The allocation of B is done in this function.
+        *** matrix_to_stl(gene_matrix & A, stl_matrix & A_stl) copy the content of an gene_matrix A into an stl_matrix A_stl.
+             The size of A_STL must corresponds to the size of A.
+        *** vector_to_stl(gene_vector & A, stl_vector & A_stl) copy the content of an gene_vector A into an stl_vector A_stl.
+             The size of B_STL must corresponds to the size of B.
+	*** copy_matrix(gene_matrix & source, gene_matrix & cible, int N) : copy the content of source in cible. Both source
+		and cible must be sized NxN.
+	*** copy_vector(gene_vector & source, gene_vector & cible, int N) : copy the content of source in cible. Both source
+ 		and cible must be sized N.
+
+	and the following method corresponding to the action one wants to be benchmarked :
+
+	***  matrix_vector_product(const gene_matrix & A, const gene_vector & B, gene_vector & X, int N)
+	***  matrix_matrix_product(const gene_matrix & A, const gene_matrix & B, gene_matrix & X, int N)
+        ***  ata_product(const gene_matrix & A, gene_matrix & X, int N)
+	***  aat_product(const gene_matrix & A, gene_matrix & X, int N)
+        ***  axpy(real coef, const gene_vector & X, gene_vector & Y, int N)
+
+ The bench algorithm (generic_bench/bench.hh) is templated with an action itself templated with
+ an interface. A typical main.cpp source stored in a given library directory libs/A_LIB
+ looks like :
+
+ bench< AN_ACTION < AN_INTERFACE > >( 10 , 1000 , 50 ) ;
+
+ this function will produce XY data file containing measured  mflops as a function of the size for 50
+ sizes between 10 and 10000.
+
+ This algorithm can be adapted by providing a given Perf_Analyzer object which determines how the time
+ measurements must be done. For example, the X86_Perf_Analyzer use the asm rdtsc function and provides
+ a very fast and accurate (but less portable) timing method. The default is the Portable_Perf_Analyzer
+ so
+
+ bench< AN_ACTION < AN_INTERFACE > >( 10 , 1000 , 50 ) ;
+
+ is equivalent to
+
+ bench< Portable_Perf_Analyzer,AN_ACTION < AN_INTERFACE > >( 10 , 1000 , 50 ) ;
+
+ If your system supports it we suggest to use a mixed implementation (X86_perf_Analyzer+Portable_Perf_Analyzer).
+ replace
+     bench<Portable_Perf_Analyzer,Action>(size_min,size_max,nb_point);
+ with
+     bench<Mixed_Perf_Analyzer,Action>(size_min,size_max,nb_point);
+ in generic/bench.hh
+
+.

+# LibXml2 is considered to be found, if both LIBXML2_LIBRARIES and

+# If it is not found and REQUIRED was used, it fails with FATAL_ERROR, 
+# independent whether QUIET was used or not.
+#
+# If it is found, the location is reported using the VAR1 argument, so 
+# here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
+# If the second argument is DEFAULT_MSG, the message in the failure case will

+The tensor benchmark suite is made of several parts.
+
+The first part is a generic suite, in which each benchmark comes in 2 flavors: one that runs on CPU, and one that runs on GPU.
+
+To compile the floating point CPU benchmarks, simply call:
+g++ tensor_benchmarks_cpu.cc benchmark_main.cc -I ../../ -std=c++11 -O3 -DNDEBUG -pthread -mavx -o benchmarks_cpu
+
+To compile the floating point GPU benchmarks, simply call:
+nvcc tensor_benchmarks_gpu.cu benchmark_main.cc -I ../../ -std=c++11 -O2 -DNDEBUG -use_fast_math -ftz=true -arch compute_35 -o benchmarks_gpu
+
+We also provide a version of the generic GPU tensor benchmarks that uses half floats (aka fp16) instead of regular floats. To compile these benchmarks, simply call the command line below. You'll need a recent GPU that supports compute capability 5.3 or higher to run them and nvcc 7.5 or higher to compile the code.
+nvcc tensor_benchmarks_fp16_gpu.cu benchmark_main.cc -I ../../ -std=c++11 -O2 -DNDEBUG -use_fast_math -ftz=true -arch compute_53 -o benchmarks_fp16_gpu
+
+last but not least, we also provide a suite of benchmarks to measure the scalability of the contraction code on CPU. To compile these benchmarks, call
+g++ contraction_benchmarks_cpu.cc benchmark_main.cc -I ../../ -std=c++11 -O3 -DNDEBUG -pthread -mavx -o benchmarks_cpu
+
+To compile the benchmark for SYCL, using ComputeCpp you currently need 2 passes (only for translation units containing device code):
+1. The device compilation pass that generates the device code (SYCL kernels and referenced device functions) and glue code needed by the host compiler to reference the device code from host code.
+{ComputeCpp_ROOT}/bin/compute++ -I ../../ -I {ComputeCpp_ROOT}/include/ -std=c++11 -mllvm -inline-threshold=1000 -Wno-ignored-attributes -sycl -intelspirmetadata -emit-llvm -no-serial-memop -sycl-compress-name -DBUILD_PLATFORM_SPIR -DNDBUG -O3 -c tensor_benchmarks_sycl.cc
+2. The host compilation pass that generates the final host binary.

+#
+# A. Default behavior
+#
+# this macro adds an executable <testname> as well as a ctest test
+# named <testname> too.
+#
+# On platforms with bash simply run:
+#   "ctest -V" or "ctest -V -R <testname>"
+# On other platform use ctest as usual
+#
+# B. Multi-part behavior
+#
+# If the source file matches the regexp
+#    CALL_SUBTEST_[0-9]+|EIGEN_TEST_PART_[0-9]+
+# then it is interpreted as a multi-part test. The behavior then depends on the
+# CMake option EIGEN_SPLIT_LARGE_TESTS, which is ON by default.
+#
+# If EIGEN_SPLIT_LARGE_TESTS is OFF, the behavior is the same as in A (the multi-part
+# aspect is ignored).
+#
+# If EIGEN_SPLIT_LARGE_TESTS is ON, the test is split into multiple executables
+#   test_<testname>_<N>
+# where N runs from 1 to the greatest occurence found in the source file. Each of these
+# executables is built passing -DEIGEN_TEST_PART_N. This allows to split large tests
+# into smaller executables.
+#

+# - Find BLAS library
+# This module finds an installed fortran library that implements the BLAS
+# linear-algebra interface (see http://www.netlib.org/blas/).
+# The list of libraries searched for is taken
+# from the autoconf macro file, acx_blas.m4 (distributed at
+# http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).
+#
+# This module sets the following variables:
+#  BLAS_FOUND - set to true if a library implementing the BLAS interface
+#    is found
+#  BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
+#    and -L).
+#  BLAS_COMPILER_FLAGS - uncached list of required compiler flags (including -I for mkl headers).
+#  BLAS_LIBRARIES - uncached list of libraries (using full path name) to
+#    link against to use BLAS
+#  BLAS95_LIBRARIES - uncached list of libraries (using full path name)
+#    to link against to use BLAS95 interface
+#  BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
+#    is found
+#  BLA_STATIC  if set on this determines what kind of linkage we do (static)
+#  BLA_VENDOR  if set checks only the specified vendor, if not set checks
+#     all the possibilities
+#  BLAS_VENDOR_FOUND stores the BLAS vendor found 
+#  BLA_F95     if set on tries to find the f95 interfaces for BLAS/LAPACK
+# The user can give specific paths where to find the libraries adding cmake

+#     Here is the order of precedence:
+#     1) we look in cmake variable BLAS_LIBDIR or BLAS_DIR (we guess the libdirs) if defined
+#     2) we look in environment variable BLAS_LIBDIR or BLAS_DIR (we guess the libdirs) if defined
+#     3) we look in common environnment variables depending on the system (INCLUDE, C_INCLUDE_PATH, CPATH - LIB, DYLD_LIBRARY_PATH, LD_LIBRARY_PATH)
+#     4) we look in common system paths depending on the system, see for example paths contained in the following cmake variables:
+#       - CMAKE_PLATFORM_IMPLICIT_INCLUDE_DIRECTORIES, CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES
+#       - CMAKE_C_IMPLICIT_INCLUDE_DIRECTORIES, CMAKE_C_IMPLICIT_LINK_DIRECTORIES

+# - Find BLAS EXTENDED for MORSE projects: find include dirs and libraries
+#
+# This module allows to find BLAS libraries by calling the official FindBLAS module
+# and handles the creation of different library lists whether the user wishes to link
+# with a sequential BLAS or a multihreaded (BLAS_SEQ_LIBRARIES and BLAS_PAR_LIBRARIES).
+# BLAS is detected with a FindBLAS call then if the BLAS vendor is Intel10_64lp, ACML
+# or IBMESSLMT then the module attempts to find the corresponding multithreaded libraries.
+#
+# The following variables have been added to manage links with sequential or multithreaded
+# versions:
+#  BLAS_INCLUDE_DIRS  - BLAS include directories
+#  BLAS_LIBRARY_DIRS  - Link directories for BLAS libraries
+#  BLAS_SEQ_LIBRARIES - BLAS component libraries to be linked (sequential)
+#  BLAS_PAR_LIBRARIES - BLAS component libraries to be linked (multithreaded)

+# - Find HWLOC include dirs and libraries
+# Use this module by invoking find_package with the form:
+#  find_package(HWLOC
+#               [REQUIRED]) # Fail with error if hwloc is not found
+#
+# This module finds headers and hwloc library.
+# Results are reported in variables:
+#  HWLOC_FOUND           - True if headers and requested libraries were found
+#  HWLOC_INCLUDE_DIRS    - hwloc include directories
+#  HWLOC_LIBRARY_DIRS    - Link directories for hwloc libraries
+#  HWLOC_LIBRARIES       - hwloc component libraries to be linked
+#
+# The user can give specific paths where to find the libraries adding cmake
+# options at configure (ex: cmake path/to/project -DHWLOC_DIR=path/to/hwloc):
+#  HWLOC_DIR             - Where to find the base directory of hwloc
+#  HWLOC_INCDIR          - Where to find the header files
+#  HWLOC_LIBDIR          - Where to find the library files
+# The module can also look for the following environment variables if paths
+# are not given as cmake variable: HWLOC_DIR, HWLOC_INCDIR, HWLOC_LIBDIR

+# Find LAPACK library
+#
+# This module finds an installed library that implements the LAPACK
+# linear-algebra interface (see http://www.netlib.org/lapack/).
+# The approach follows mostly that taken for the autoconf macro file, acx_lapack.m4
+# (distributed at http://ac-archive.sourceforge.net/ac-archive/acx_lapack.html).
+#
+# This module sets the following variables:
+#  LAPACK_FOUND - set to true if a library implementing the LAPACK interface
+#    is found
+#  LAPACK_INCLUDE_DIR - Directories containing the LAPACK header files
+#  LAPACK_DEFINITIONS - Compilation options to use LAPACK
+#  LAPACK_LINKER_FLAGS - Linker flags to use LAPACK (excluding -l
+#    and -L).
+#  LAPACK_LIBRARIES_DIR - Directories containing the LAPACK libraries.
+#     May be null if LAPACK_LIBRARIES contains libraries name using full path.
+#  LAPACK_LIBRARIES - List of libraries to link against LAPACK interface.
+#     May be null if the compiler supports auto-link (e.g. VC++).
+#  LAPACK_USE_FILE - The name of the cmake module to include to compile
+#     applications or libraries using LAPACK.
+#
+# This module was modified by CGAL team:
+# - find libraries for a C++ compiler, instead of Fortran
+# - added LAPACK_INCLUDE_DIR, LAPACK_DEFINITIONS and LAPACK_LIBRARIES_DIR
+# - removed LAPACK95_LIBRARIES
+

+# - Find PASTIX include dirs and libraries
+# Use this module by invoking find_package with the form:
+#  find_package(PASTIX
+#               [REQUIRED] # Fail with error if pastix is not found
+#               [COMPONENTS <comp1> <comp2> ...] # dependencies
+#              )
+#
+#  PASTIX depends on the following libraries:
+#   - Threads, m, rt
+#   - MPI
+#   - HWLOC
+#   - BLAS
+#
+#  COMPONENTS are optional libraries PASTIX could be linked with,
+#  Use it to drive detection of a specific compilation chain
+#  COMPONENTS can be some of the following:
+#   - MPI: to activate detection of the parallel MPI version (default)
+#        it looks for Threads, HWLOC, BLAS, MPI and ScaLAPACK libraries
+#   - SEQ: to activate detection of the sequential version (exclude MPI version)
+#   - STARPU: to activate detection of StarPU version
+#   it looks for MPI version of StarPU (default behaviour)
+#   if SEQ and STARPU are given, it looks for a StarPU without MPI
+#   - STARPU_CUDA: to activate detection of StarPU with CUDA
+#   - STARPU_FXT: to activate detection of StarPU with FxT
+#   - SCOTCH: to activate detection of PASTIX linked with SCOTCH
+#   - PTSCOTCH: to activate detection of PASTIX linked with SCOTCH
+#   - METIS: to activate detection of PASTIX linked with SCOTCH
+#
+# This module finds headers and pastix library.
+# Results are reported in variables:
+#  PASTIX_FOUND            - True if headers and requested libraries were found
+#  PASTIX_LINKER_FLAGS     - list of required linker flags (excluding -l and -L)
+#  PASTIX_INCLUDE_DIRS     - pastix include directories
+#  PASTIX_LIBRARY_DIRS     - Link directories for pastix libraries
+#  PASTIX_LIBRARIES        - pastix libraries
+#  PASTIX_INCLUDE_DIRS_DEP - pastix + dependencies include directories
+#  PASTIX_LIBRARY_DIRS_DEP - pastix + dependencies link directories
+#  PASTIX_LIBRARIES_DEP    - pastix libraries + dependencies
+#
+# The user can give specific paths where to find the libraries adding cmake
+# options at configure (ex: cmake path/to/project -DPASTIX_DIR=path/to/pastix):
+#  PASTIX_DIR              - Where to find the base directory of pastix
+#  PASTIX_INCDIR           - Where to find the header files
+#  PASTIX_LIBDIR           - Where to find the library files
+# The module can also look for the following environment variables if paths
+# are not given as cmake variable: PASTIX_DIR, PASTIX_INCDIR, PASTIX_LIBDIR

+# - Find SCOTCH include dirs and libraries
+# Use this module by invoking find_package with the form:
+#  find_package(SCOTCH
+#               [REQUIRED]             # Fail with error if scotch is not found
+#               [COMPONENTS <comp1> <comp2> ...] # dependencies
+#              )
+#
+#  COMPONENTS can be some of the following:
+#   - ESMUMPS: to activate detection of Scotch with the esmumps interface
+#
+# This module finds headers and scotch library.
+# Results are reported in variables:
+#  SCOTCH_FOUND           - True if headers and requested libraries were found
+#  SCOTCH_INCLUDE_DIRS    - scotch include directories
+#  SCOTCH_LIBRARY_DIRS    - Link directories for scotch libraries
+#  SCOTCH_LIBRARIES       - scotch component libraries to be linked
+#  SCOTCH_INTSIZE         - Number of octets occupied by a SCOTCH_Num
+#
+# The user can give specific paths where to find the libraries adding cmake
+# options at configure (ex: cmake path/to/project -DSCOTCH=path/to/scotch):
+#  SCOTCH_DIR             - Where to find the base directory of scotch
+#  SCOTCH_INCDIR          - Where to find the header files
+#  SCOTCH_LIBDIR          - Where to find the library files
+# The module can also look for the following environment variables if paths
+# are not given as cmake variable: SCOTCH_DIR, SCOTCH_INCDIR, SCOTCH_LIBDIR

+# This is still pretty basic as the python extension to gdb is still pretty basic.

+# This code supports fixed size as well as dynamic size matrices
+
+# To use it:
+#
+# * Create a directory and put the file as well as an empty __init__.py in 
+#   that directory.
+# * Create a ~/.gdbinit file, that contains the following:
+#      python
+#      import sys
+#      sys.path.insert(0, '/path/to/eigen/printer/directory')

+\section CompatibilitySupport Eigen2 compatibility support
+
+Up to version 3.2 %Eigen provides <a href="http://eigen.tuxfamily.org/dox-3.2/Eigen2SupportModes.html">Eigen2 support modes</a>. These are removed now, because they were barely used anymore and became hard to maintain after internal re-designs.
+You can still use them by first <a href="http://eigen.tuxfamily.org/dox-3.2/Eigen2ToEigen3.html">porting your code to Eigen 3.2</a>.
+
+\section Using The USING_PART_OF_NAMESPACE_EIGEN macro
+
+The USING_PART_OF_NAMESPACE_EIGEN macro has been removed. In Eigen 3, just do:
+\code
+using namespace Eigen;
+\endcode
+
+\section ComplexDot Dot products over complex numbers
+
+This is the single trickiest change between Eigen 2 and Eigen 3. It only affects code using \c std::complex numbers as scalar type.
+
+Eigen 2's dot product was linear in the first variable. Eigen 3's dot product is linear in the second variable. In other words, the Eigen 2 code \code x.dot(y) \endcode is equivalent to the Eigen 3 code \code y.dot(x) \endcode In yet other words, dot products are complex-conjugated in Eigen 3 compared to Eigen 2. The switch to the new convention was commanded by common usage, especially with the notation \f$ x^Ty \f$ for dot products of column-vectors.
+
+\section VectorBlocks Vector blocks
+
+<table class="manual">
+<tr><th>Eigen 2</th><th>Eigen 3</th></th>

+vector.end(length)

+\endcode</td><td>\code
+vector.head(length)
+vector.head<length>()

+<tr><td>\code
+matrix.corner(TopLeft,r,c)

+matrix.corner(BottomLeft,r,c)

+matrix.topLeftCorner<r,c>()
+matrix.topRightCorner<r,c>()
+matrix.bottomLeftCorner<r,c>()
+matrix.bottomRightCorner<r,c>()
+\endcode</td>
+</tr>
+</table>
+
+Notice that Eigen3 also provides these new convenience methods: topRows(), bottomRows(), leftCols(), rightCols(). See in class DenseBase.
+
+\section CoefficientWiseOperations Coefficient wise operations
+
+In Eigen2, coefficient wise operations which have no proper mathematical definition (as a coefficient wise product)
+were achieved using the .cwise() prefix, e.g.:
+\code a.cwise() * b \endcode
+In Eigen3 this .cwise() prefix has been superseded by a new kind of matrix type called
+Array for which all operations are performed coefficient wise. You can easily view a matrix as an array and vice versa using
+the MatrixBase::array() and ArrayBase::matrix() functions respectively. Here is an example:
+\code
+Vector4f a, b, c;
+c = a.array() * b.array();
+\endcode
+Note that the .array() function is not at all a synonym of the deprecated .cwise() prefix.
+While the .cwise() prefix changed the behavior of the following operator, the array() function performs
+a permanent conversion to the array world. Therefore, for binary operations such as the coefficient wise product,
+both sides must be converted to an \em array as in the above example. On the other hand, when you
+concatenate multiple coefficient wise operations you only have to do the conversion once, e.g.:
+\code
+Vector4f a, b, c;
+c = a.array().abs().pow(3) * b.array().abs().sin();
+\endcode
+With Eigen2 you would have written:
+\code
+c = (a.cwise().abs().cwise().pow(3)).cwise() * (b.cwise().abs().cwise().sin());
+\endcode
+
+\section PartAndExtract Triangular and self-adjoint matrices
+
+In Eigen 2 you had to play with the part, extract, and marked functions to deal with triangular and selfadjoint matrices. In Eigen 3, all these functions have been removed in favor of the concept of \em views:
+
+<table class="manual">
+<tr><th>Eigen 2</th><th>Eigen 3</th></tr>
+<tr><td>\code
+A.part<UpperTriangular>();
+A.part<StrictlyLowerTriangular>(); \endcode</td>
+<td>\code
+A.triangularView<Upper>()
+A.triangularView<StrictlyLower>()\endcode</td></tr>
+<tr><td>\code
+A.extract<UpperTriangular>();
+A.extract<StrictlyLowerTriangular>();\endcode</td>
+<td>\code
+A.triangularView<Upper>()
+A.triangularView<StrictlyLower>()\endcode</td></tr>

+<tr><td colspan="2"></td></tr>
+<tr><td>\code
+A.part<SelfAdfjoint|UpperTriangular>();
+A.extract<SelfAdfjoint|LowerTriangular>();\endcode</td>

+
+
+\section Decompositions Matrix decompositions
+
+Some of Eigen 2's matrix decompositions have been renamed in Eigen 3, while some others have been removed and are replaced by other decompositions in Eigen 3.
+
+<table class="manual">

+the selfadjointView API allows you to select the \n
+triangular part to work on</td></tr>
+</table>
+
+\section GeometryModule Changes in the Geometry module
+
+The Geometry module is the one that changed the most. If you rely heavily on it, it's probably a good idea to use the <a href="http://eigen.tuxfamily.org/dox-3.2/Eigen2SupportModes.html">"Eigen 2 support modes"</a> to perform your migration.
+
+\section Transform The Transform class
+
+In Eigen 2, the Transform class didn't really know whether it was a projective or affine transformation. In Eigen 3, it takes a new \a Mode template parameter, which indicates whether it's \a Projective or \a Affine transform. There is no default value.
+
+The Transform3f (etc) typedefs are no more. In Eigen 3, the Transform typedefs explicitly refer to the \a Projective and \a Affine modes:
+
+<table class="manual">
+<tr><th>Eigen 2</th><th>Eigen 3</th><th>Notes</th></tr>
+<tr>
+  <td> Transform3f </td>
+  <td> Affine3f or Projective3f </td>
+  <td> Of course 3f is just an example here </td>
+</tr>
+</table>
+
+
+\section LazyVsNoalias Lazy evaluation and noalias
+
+In Eigen all operations are performed in a lazy fashion except the matrix products which are always evaluated into a temporary by default.
+In Eigen2, lazy evaluation could be enforced by tagging a product using the .lazy() function. However, in complex expressions it was not
+easy to determine where to put the lazy() function. In Eigen3, the lazy() feature has been superseded by the MatrixBase::noalias() function
+which can be used on the left hand side of an assignment when no aliasing can occur. Here is an example:
+\code
+MatrixXf a, b, c;
+...
+c.noalias() += 2 * a.transpose() * b;
+\endcode
+However, the noalias mechanism does not cover all the features of the old .lazy(). Indeed, in some extremely rare cases,
+it might be useful to explicit request for a lay product, i.e., for a product which will be evaluated one coefficient at once, on request,
+just like any other expressions. To this end you can use the MatrixBase::lazyProduct() function, however we strongly discourage you to
+use it unless you are sure of what you are doing, i.e., you have rigourosly measured a speed improvement.
+
+\section AlignMacros Alignment-related macros
+
+The EIGEN_ALIGN_128 macro has been renamed to EIGEN_ALIGN16. Don't be surprised, it's just that we switched to counting in bytes ;-)
+
+The \link TopicPreprocessorDirectivesPerformance EIGEN_DONT_ALIGN \endlink option still exists in Eigen 3, but it has a new cousin: \link TopicPreprocessorDirectivesPerformance  EIGEN_DONT_ALIGN_STATICALLY.\endlink It allows to get rid of all static alignment issues while keeping alignment of dynamic-size heap-allocated arrays. Vectorization of statically allocated arrays is still preserved (unless you define \link TopicPreprocessorDirectivesPerformance EIGEN_UNALIGNED_VECTORIZE \endlink =0), at the cost of unaligned memory stores.
+
+\section AlignedMap Aligned Map objects
+
+A common issue with Eigen 2 was that when mapping an array with Map, there was no way to tell Eigen that your array was aligned. There was a ForceAligned option but it didn't mean that; it was just confusing and has been removed.
+
+New in Eigen3 is the #Aligned option. See the documentation of class Map. Use it like this:
+\code
+Map<Vector4f, Aligned> myMappedVector(some_aligned_array);
+\endcode
+There also are related convenience static methods, which actually are the preferred way as they take care of such things as constness:
+\code
+result = Vector4f::MapAligned(some_aligned_array);
+\endcode
+
+\section StdContainers STL Containers
+
+In Eigen2, <tt>\#include\<Eigen/StdVector\></tt> tweaked std::vector to automatically align elements. The problem was that that was quite invasive. In Eigen3, we only override standard behavior if you use Eigen::aligned_allocator<T> as your allocator type. So for example, if you use std::vector<Matrix4f>, you need to do the following change (note that aligned_allocator is under namespace Eigen):
+
+<table class="manual">
+<tr><th>Eigen 2</th><th>Eigen 3</th></tr>
+<tr>
+  <td> \code std::vector<Matrix4f> \endcode </td>
+  <td> \code std::vector<Matrix4f, aligned_allocator<Matrix4f> > \endcode </td>
+</tr>
+</table>
+
+\section eiPrefix Internal ei_ prefix
+
+In Eigen2, global internal functions and structures were prefixed by \c ei_. In Eigen3, they all have been moved into the more explicit \c internal namespace. So, e.g., \c ei_sqrt(x) now becomes \c internal::sqrt(x). Of course it is not recommended to rely on Eigen's internal features.

+
+\section Experimental_summary Summary
+
+With the 2.0 release, Eigen's API is, to a large extent, stable. However, we wish to retain the freedom to make API incompatible changes. To that effect, we call many parts of Eigen "experimental" which means that they are not subject to API stability guarantee.
+
+Our goal is that for the 2.1 release (expected in July 2009) most of these parts become API-stable too.
+
+We are aware that API stability is a major concern for our users. That's why it's a priority for us to reach it, but at the same time we're being serious about not calling Eigen API-stable too early.
+
+Experimental features may at any time:
+\li be removed;
+\li be subject to an API incompatible change;
+\li introduce API or ABI incompatible changes in your own code if you let them affect your API or ABI.
+
+\section Experimental_modules Experimental modules
+
+The following modules are considered entirely experimental, and we make no firm API stability guarantee about them for the time being:
+\li SVD
+\li QR
+\li Cholesky
+\li Sparse
+\li Geometry (this one should be mostly stable, but it's a little too early to make a formal guarantee)
+
+\section Experimental_core Experimental parts of the Core module
+
+In the Core module, the only classes subject to ABI stability guarantee (meaning that you can use it for data members in your public ABI) is:
+\li Matrix
+\li Map
+
+All other classes offer no ABI guarantee, e.g. the layout of their data can be changed.
+
+The only classes subject to (even partial) API stability guarantee (meaning that you can safely construct and use objects) are:
+\li MatrixBase : partial API stability (see below)
+\li Matrix : full API stability (except for experimental stuff inherited from MatrixBase)
+\li Map : full API stability (except for experimental stuff inherited from MatrixBase)
+
+All other classes offer no direct API guarantee, e.g. their methods can be changed; however notice that most classes inherit MatrixBase and that this is where most of their API comes from -- so in practice most of the API is stable.
+
+A few MatrixBase methods are considered experimental, hence not part of any API stability guarantee:
+\li all methods documented as internal
+\li all methods hidden in the Doxygen documentation
+\li all methods marked as experimental
+\li all methods defined in experimental modules

+/** \page TopicClassHierarchy The class hierarchy
+
+This page explains the design of the core classes in Eigen's class hierarchy and how they fit together. Casual
+users probably need not concern themselves with these details, but it may be useful for both advanced users
+and Eigen developers.
+
+\eigenAutoToc
+
+
+\section TopicClassHierarchyPrinciples Principles
+
+Eigen's class hierarchy is designed so that virtual functions are avoided where their overhead would
+significantly impair performance. Instead, Eigen achieves polymorphism with the Curiously Recurring Template
+Pattern (CRTP). In this pattern, the base class (for instance, \c MatrixBase) is in fact a template class, and
+the derived class (for instance, \c Matrix) inherits the base class with the derived class itself as a
+template argument (in this case, \c Matrix inherits from \c MatrixBase&lt;Matrix&gt;). This allows Eigen to
+resolve the polymorphic function calls at compile time.
+
+In addition, the design avoids multiple inheritance. One reason for this is that in our experience, some
+compilers (like MSVC) fail to perform empty base class optimization, which is crucial for our fixed-size
+types.
+
+
+\section TopicClassHierarchyCoreClasses The core classes
+
+These are the classes that you need to know about if you want to write functions that accept or return Eigen
+objects.
+
+  - Matrix means plain dense matrix. If \c m is a \c %Matrix, then, for instance, \c m+m is no longer a 
+    \c %Matrix, it is a "matrix expression".
+  - MatrixBase means dense matrix expression. This means that a \c %MatrixBase is something that can be
+    added, matrix-multiplied, LU-decomposed, QR-decomposed... All matrix expression classes, including 
+    \c %Matrix itself, inherit \c %MatrixBase.
+  - Array means plain dense array. If \c x is an \c %Array, then, for instance, \c x+x is no longer an 
+    \c %Array, it is an "array expression".
+  - ArrayBase means dense array expression. This means that an \c %ArrayBase is something that can be
+    added, array-multiplied, and on which you can perform all sorts of array operations... All array
+    expression classes, including \c %Array itself, inherit \c %ArrayBase.
+  - DenseBase means dense (matrix or array) expression. Both \c %ArrayBase and \c %MatrixBase inherit
+    \c %DenseBase. \c %DenseBase is where all the methods go that apply to dense expressions regardless of
+    whether they are matrix or array expressions. For example, the \link DenseBase::block() block(...) \endlink
+    methods are in \c %DenseBase.
+
+\section TopicClassHierarchyBaseClasses Base classes
+
+These classes serve as base classes for the five core classes mentioned above. They are more internal and so
+less interesting for users of the Eigen library.
+
+  - PlainObjectBase means dense (matrix or array) plain object, i.e. something that stores its own dense
+    array of coefficients. This is where, for instance, the \link PlainObjectBase::resize() resize() \endlink
+    methods go. \c %PlainObjectBase is inherited by \c %Matrix and by \c %Array. But above, we said that 
+    \c %Matrix inherits \c %MatrixBase and \c %Array inherits \c %ArrayBase. So does that mean multiple
+    inheritance? No, because \c %PlainObjectBase \e itself inherits \c %MatrixBase or \c %ArrayBase depending
+    on whether we are in the matrix or array case. When we said above that \c %Matrix inherited 
+    \c %MatrixBase, we omitted to say it does so indirectly via \c %PlainObjectBase. Same for \c %Array.
+  - DenseCoeffsBase means something that has dense coefficient accessors. It is a base class for
+    \c %DenseBase. The reason for \c %DenseCoeffsBase to exist is that the set of available coefficient
+    accessors is very different depending on whether a dense expression has direct memory access or not (the
+    \c DirectAccessBit flag). For example, if \c x is a plain matrix, then \c x has direct access, and 
+    \c x.transpose() and \c x.block(...) also have direct access, because their coefficients can be read right
+    off memory, but for example, \c x+x does not have direct memory access, because obtaining any of its
+    coefficients requires a computation (an addition), it can't be just read off memory.
+  - EigenBase means anything that can be evaluated into a plain dense matrix or array (even if that would
+    be a bad idea). \c %EigenBase is really the absolute base class for anything that remotely looks like a
+    matrix or array. It is a base class for \c %DenseCoeffsBase, so it sits below all our dense class
+    hierarchy, but it is not limited to dense expressions. For example, \c %EigenBase is also inherited by
+    diagonal matrices, sparse matrices, etc...

+/** \eigenManualPage CoeffwiseMathFunctions Catalog of coefficient-wise math functions
+
+
+<!-- <span style="font-size:300%; color:red; font-weight: 900;">!WORK IN PROGRESS!</span> -->
+
+This table presents a catalog of the coefficient-wise math functions supported by %Eigen.
+In this table, \c a, \c b, refer to Array objects or expressions, and \c m refers to a linear algebra Matrix/Vector object. Standard scalar types are abbreviated as follows:
+  - \c int: \c i32
+  - \c float: \c f
+  - \c double: \c d
+  - \c std::complex<float>: \c cf
+  - \c std::complex<double>: \c cd
+
+For each row, the first column list the equivalent calls for arrays, and matrices when supported. Of course, all functions are available for matrices by first casting it as an array: \c m.array().
+
+The third column gives some hints in the underlying scalar implementation. In most cases, %Eigen does not implement itself the math function but relies on the STL for standard scalar types, or user-provided functions for custom scalar types.
+For instance, some simply calls the respective function of the STL while preserving <a href="http://en.cppreference.com/w/cpp/language/adl">argument-dependent lookup</a> for custom types.
+The following:
+\code
+using std::foo;
+foo(a[i]);
+\endcode
+means that the STL's function \c std::foo will be potentially called if it is compatible with the underlying scalar type. If not, then the user must ensure that an overload of the function foo is available for the given scalar type (usually defined in the same namespace as the given scalar type).
+This also means that, unless specified, if the function \c std::foo is available only in some recent c++ versions (e.g., c++11), then the respective %Eigen's function/method will be usable on standard types only if the compiler support the required c++ version.

+/** \page TopicCustomizing_CustomScalar Using custom scalar types
+\anchor user_defined_scalars
+
+By default, Eigen currently supports standard floating-point types (\c float, \c double, \c std::complex<float>, \c std::complex<double>, \c long \c double), as well as all native integer types (e.g., \c int, \c unsigned \c int, \c short, etc.), and \c bool.
+On x86-64 systems, \c long \c double permits to locally enforces the use of x87 registers with extended accuracy (in comparison to SSE).
+
+In order to add support for a custom type \c T you need:
+-# make sure the common operator (+,-,*,/,etc.) are supported by the type \c T
+-# add a specialization of struct Eigen::NumTraits<T> (see \ref NumTraits)
+-# define the math functions that makes sense for your type. This includes standard ones like sqrt, pow, sin, tan, conj, real, imag, etc, as well as abs2 which is Eigen specific.
+     (see the file Eigen/src/Core/MathFunctions.h)
+
+The math function should be defined in the same namespace than \c T, or in the \c std namespace though that second approach is not recommended.
+
+Here is a concrete example adding support for the Adolc's \c adouble type. <a href="https://projects.coin-or.org/ADOL-C">Adolc</a> is an automatic differentiation library. The type \c adouble is basically a real value tracking the values of any number of partial derivatives.

+This other example adds support for the \c mpq_class type from <a href="https://gmplib.org/">GMP</a>. It shows in particular how to change the way Eigen picks the best pivot during LU factorization. It selects the coefficient with the highest score, where the score is by default the absolute value of a number, but we can define a different score, for instance to prefer pivots with a more compact representation (this is an example, not a recommendation). Note that the scores should always be non-negative and only zero is allowed to have a score of zero. Also, this can interact badly with thresholds for inexact scalar types.

+
+Before inheriting from Matrix, be really, I mean REALLY, sure that using
+EIGEN_MATRIX_PLUGIN is not what you really want (see previous section).
+If you just need to add few members to Matrix, this is the way to go.
+
+An example of when you actually need to inherit Matrix, is when you
+have several layers of heritage such as 
+MyVerySpecificVector1, MyVerySpecificVector2 -> MyVector1 -> Matrix and
+MyVerySpecificVector3, MyVerySpecificVector4 -> MyVector2 -> Matrix.
+
+In order for your object to work within the %Eigen framework, you need to
+define a few members in your inherited class.
+
+Here is a minimalistic example:
+
+\include CustomizingEigen_Inheritance.cpp
+
+Output: \verbinclude CustomizingEigen_Inheritance.out
+
+This is the kind of error you can get if you don't provide those methods
+\verbatim
+error: no match for ‘operator=’ in ‘v = Eigen::operator*(

+/** \page TopicCustomizing_NullaryExpr Matrix manipulation via nullary-expressions
+
+
+The main purpose of the class CwiseNullaryOp is to define \em procedural matrices such as constant or random matrices as returned by the Ones(), Zero(), Constant(), Identity() and Random() methods.
+Nevertheless, with some imagination it is possible to accomplish very sophisticated matrix manipulation with minimal efforts such that \ref TopicNewExpressionType "implementing new expression" is rarely needed.
+
+\section NullaryExpr_Circulant Example 1: circulant matrix
+
+To explore these possibilities let us start with the  \em circulant example of the \ref TopicNewExpressionType "implementing new expression" topic.
+Let us recall that a circulant matrix is a matrix where each column is the same as the
+column to the left, except that it is cyclically shifted downwards.
+For example, here is a 4-by-4 circulant matrix:
+\f[ \begin{bmatrix}
+    1 & 8 & 4 & 2 \\
+    2 & 1 & 8 & 4 \\
+    4 & 2 & 1 & 8 \\
+    8 & 4 & 2 & 1
+\end{bmatrix} \f]
+A circulant matrix is uniquely determined by its first column. We wish
+to write a function \c makeCirculant which, given the first column,
+returns an expression representing the circulant matrix.
+
+For this exercise, the return type of \c makeCirculant will be a CwiseNullaryOp that we need to instantiate with:
+1 - a proper \c circulant_functor storing the input vector and implementing the adequate coefficient accessor \c operator(i,j)
+2 - a template instantiation of class Matrix conveying compile-time information such as the scalar type, sizes, and preferred storage layout.
+
+Calling \c ArgType the type of the input vector, we can construct the equivalent squared Matrix type as follows:
+
+\snippet make_circulant2.cpp square
+
+This little helper structure will help us to implement our \c makeCirculant function as follows:
+
+\snippet make_circulant2.cpp makeCirculant
+
+As usual, our function takes as argument a \c MatrixBase (see this \ref TopicFunctionTakingEigenTypes "page" for more details).
+Then, the CwiseNullaryOp object is constructed through the DenseBase::NullaryExpr static method with the adequate runtime sizes.
+
+Then, we need to implement our \c circulant_functor, which is a straightforward exercise:
+
+\snippet make_circulant2.cpp circulant_func
+
+We are now all set to try our new feature:
+
+\snippet make_circulant2.cpp main
+
+
+If all the fragments are combined, the following output is produced,
+showing that the program works as expected:
+
+\include make_circulant2.out
+
+This implementation of \c makeCirculant is much simpler than \ref TopicNewExpressionType "defining a new expression" from scratch.
+
+
+\section NullaryExpr_Indexing Example 2: indexing rows and columns
+
+The goal here is to mimic MatLab's ability to index a matrix through two vectors of indices referencing the rows and columns to be picked respectively, like this:
+
+\snippet nullary_indexing.out main1
+
+To this end, let us first write a nullary-functor storing references to the input matrix and to the two arrays of indices, and implementing the required \c operator()(i,j):
+
+\snippet nullary_indexing.cpp functor
+
+Then, let's create an \c indexing(A,rows,cols) function creating the nullary expression:
+
+\snippet nullary_indexing.cpp function
+
+Finally, here is an example of how this function can be used:
+
+\snippet nullary_indexing.cpp main1
+
+This straightforward implementation is already quite powerful as the row or column index arrays can also be expressions to perform offsetting, modulo, striding, reverse, etc.
+
+\snippet nullary_indexing.cpp main2
+
+and the output is:
+
+\snippet nullary_indexing.out main2

+/** \page TopicCustomizing_Plugins Extending MatrixBase (and other classes)
+
+In this section we will see how to add custom methods to MatrixBase. Since all expressions and matrix types inherit MatrixBase, adding a method to MatrixBase make it immediately available to all expressions ! A typical use case is, for instance, to make Eigen compatible with another API.
+
+You certainly know that in C++ it is not possible to add methods to an existing class. So how that's possible ? Here the trick is to include in the declaration of MatrixBase a file defined by the preprocessor token \c EIGEN_MATRIXBASE_PLUGIN:
+\code
+class MatrixBase {
+  // ...
+  #ifdef EIGEN_MATRIXBASE_PLUGIN
+  #include EIGEN_MATRIXBASE_PLUGIN
+  #endif
+};
+\endcode
+Therefore to extend MatrixBase with your own methods you just have to create a file with your method declaration and define EIGEN_MATRIXBASE_PLUGIN before you include any Eigen's header file.
+
+You can extend many of the other classes used in Eigen by defining similarly named preprocessor symbols. For instance, define \c EIGEN_ARRAYBASE_PLUGIN if you want to extend the ArrayBase class. A full list of classes that can be extended in this way and the corresponding preprocessor symbols can be found on our page \ref TopicPreprocessorDirectives.
+
+Here is an example of an extension file for adding methods to MatrixBase: \n
+\b MatrixBaseAddons.h
+\code
+inline Scalar at(uint i, uint j) const { return this->operator()(i,j); }
+inline Scalar& at(uint i, uint j) { return this->operator()(i,j); }
+inline Scalar at(uint i) const { return this->operator[](i); }
+inline Scalar& at(uint i) { return this->operator[](i); }
+
+inline RealScalar squaredLength() const { return squaredNorm(); }
+inline RealScalar length() const { return norm(); }
+inline RealScalar invLength(void) const { return fast_inv_sqrt(squaredNorm()); }
+
+template<typename OtherDerived>
+inline Scalar squaredDistanceTo(const MatrixBase<OtherDerived>& other) const
+{ return (derived() - other.derived()).squaredNorm(); }
+
+template<typename OtherDerived>
+inline RealScalar distanceTo(const MatrixBase<OtherDerived>& other) const
+{ return internal::sqrt(derived().squaredDistanceTo(other)); }
+
+inline void scaleTo(RealScalar l) { RealScalar vl = norm(); if (vl>1e-9) derived() *= (l/vl); }
+
+inline Transpose<Derived> transposed() {return this->transpose();}
+inline const Transpose<Derived> transposed() const {return this->transpose();}
+
+inline uint minComponentId(void) const  { int i; this->minCoeff(&i); return i; }
+inline uint maxComponentId(void) const  { int i; this->maxCoeff(&i); return i; }
+
+template<typename OtherDerived>
+void makeFloor(const MatrixBase<OtherDerived>& other) { derived() = derived().cwiseMin(other.derived()); }
+template<typename OtherDerived>
+void makeCeil(const MatrixBase<OtherDerived>& other) { derived() = derived().cwiseMax(other.derived()); }
+
+const CwiseBinaryOp<internal::scalar_sum_op<Scalar>, const Derived, const ConstantReturnType>
+operator+(const Scalar& scalar) const
+{ return CwiseBinaryOp<internal::scalar_sum_op<Scalar>, const Derived, const ConstantReturnType>(derived(), Constant(rows(),cols(),scalar)); }
+
+friend const CwiseBinaryOp<internal::scalar_sum_op<Scalar>, const ConstantReturnType, Derived>
+operator+(const Scalar& scalar, const MatrixBase<Derived>& mat)
+{ return CwiseBinaryOp<internal::scalar_sum_op<Scalar>, const ConstantReturnType, Derived>(Constant(rows(),cols(),scalar), mat.derived()); }
+\endcode
+
+Then one can the following declaration in the config.h or whatever prerequisites header file of his project:
+\code
+#define EIGEN_MATRIXBASE_PLUGIN "MatrixBaseAddons.h"
+\endcode

+
+This page presents a speed comparison of the dense matrix decompositions offered by %Eigen for a wide range of square matrices and overconstrained problems.
+
+For a more general overview on the features and numerical robustness of linear solvers and decompositions, check this \link TopicLinearAlgebraDecompositions table \endlink.
+
+This benchmark has been run on a laptop equipped with an Intel core i7 \@ 2,6 GHz, and compiled with clang with \b AVX and \b FMA instruction sets enabled but without multi-threading.
+It uses \b single \b precision \b float numbers. For double, you can get a good estimate by multiplying the timings by a factor 2.
+
+The square matrices are symmetric, and for the overconstrained matrices, the reported timmings include the cost to compute the symmetric covariance matrix \f$ A^T A \f$ for the first four solvers based on Cholesky and LU, as denoted by the \b * symbol (top-right corner part of the table).
+Timings are in \b milliseconds, and factors are relative to the LLT decomposition which is the fastest but also the least general and robust.

+
+\b Observations:
+ + LLT is always the fastest solvers.
+ + For largely over-constrained problems, the cost of Cholesky/LU decompositions is dominated by the computation of the symmetric covariance matrix.
+ + For large problem sizes, only the decomposition implementing a cache-friendly blocking strategy scale well. Those include LLT, PartialPivLU, HouseholderQR, and BDCSVD. This explain why for a 4k x 4k matrix, HouseholderQR is faster than LDLT. In the future, LDLT and ColPivHouseholderQR will also implement blocking strategies.
+ + CompleteOrthogonalDecomposition is based on ColPivHouseholderQR and they thus achieve the same level of performance.

+/** \eigenManualPage TopicFixedSizeVectorizable Fixed-size vectorizable Eigen objects
+
+The goal of this page is to explain what we mean by "fixed-size vectorizable".
+
+\section FixedSizeVectorizable_summary Executive Summary
+
+An Eigen object is called "fixed-size vectorizable" if it has fixed size and that size is a multiple of 16 bytes.
+
+Examples include:
+\li Eigen::Vector2d
+\li Eigen::Vector4d
+\li Eigen::Vector4f
+\li Eigen::Matrix2d
+\li Eigen::Matrix2f
+\li Eigen::Matrix4d
+\li Eigen::Matrix4f
+\li Eigen::Affine3d
+\li Eigen::Affine3f
+\li Eigen::Quaterniond
+\li Eigen::Quaternionf
+
+\section FixedSizeVectorizable_explanation Explanation
+
+First, "fixed-size" should be clear: an Eigen object has fixed size if its number of rows and its number of columns are fixed at compile-time. So for example Matrix3f has fixed size, but MatrixXf doesn't (the opposite of fixed-size is dynamic-size).
+
+The array of coefficients of a fixed-size Eigen object is a plain "static array", it is not dynamically allocated. For example, the data behind a Matrix4f is just a "float array[16]".
+
+Fixed-size objects are typically very small, which means that we want to handle them with zero runtime overhead -- both in terms of memory usage and of speed.
+
+Now, vectorization (both SSE and AltiVec) works with 128-bit packets. Moreover, for performance reasons, these packets need to be have 128-bit alignment.
+
+So it turns out that the only way that fixed-size Eigen objects can be vectorized, is if their size is a multiple of 128 bits, or 16 bytes. Eigen will then request 16-byte alignment for these objects, and henceforth rely on these objects being aligned so no runtime check for alignment is performed.

+/** \page TopicFunctionTakingEigenTypes Writing Functions Taking %Eigen Types as Parameters
+
+%Eigen's use of expression templates results in potentially every expression being of a different type. If you pass such an expression to a function taking a parameter of type Matrix, your expression will implicitly be evaluated into a temporary Matrix, which will then be passed to the function. This means that you lose the benefit of expression templates. Concretely, this has two drawbacks:
+ \li The evaluation into a temporary may be useless and inefficient;
+ \li This only allows the function to read from the expression, not to write to it.
+
+Fortunately, all this myriad of expression types have in common that they all inherit a few common, templated base classes. By letting your function take templated parameters of these base types, you can let them play nicely with %Eigen's expression templates.
+
+\eigenAutoToc
+
+\section TopicFirstExamples Some First Examples
+
+This section will provide simple examples for different types of objects %Eigen is offering. Before starting with the actual examples, we need to recapitulate which base objects we can work with (see also \ref TopicClassHierarchy).
+
+ \li MatrixBase: The common base class for all dense matrix expressions (as opposed to array expressions, as opposed to sparse and special matrix classes). Use it in functions that are meant to work only on dense matrices.
+ \li ArrayBase: The common base class for all dense array expressions (as opposed to matrix expressions, etc). Use it in functions that are meant to work only on arrays.
+ \li DenseBase: The common base class for all dense matrix expression, that is, the base class for both \c MatrixBase and \c ArrayBase. It can be used in functions that are meant to work on both matrices and arrays.
+ \li EigenBase: The base class unifying all types of objects that can be evaluated into dense matrices or arrays, for example special matrix classes such as diagonal matrices, permutation matrices, etc. It can be used in functions that are meant to work on any such general type.
+
+<b> %EigenBase Example </b><br/><br/>
+Prints the dimensions of the most generic object present in %Eigen. It could be any matrix expressions, any dense or sparse matrix and any array.
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include function_taking_eigenbase.cpp
+</td>
+<td>
+\verbinclude function_taking_eigenbase.out
+</td></tr></table>
+<b> %DenseBase Example </b><br/><br/>
+Prints a sub-block of the dense expression. Accepts any dense matrix or array expression, but no sparse objects and no special matrix classes such as DiagonalMatrix.
+\code
+template <typename Derived>
+void print_block(const DenseBase<Derived>& b, int x, int y, int r, int c)
+{
+  std::cout << "block: " << b.block(x,y,r,c) << std::endl;
+}
+\endcode
+<b> %ArrayBase Example </b><br/><br/>
+Prints the maximum coefficient of the array or array-expression.
+\code
+template <typename Derived>
+void print_max_coeff(const ArrayBase<Derived> &a)
+{
+  std::cout << "max: " << a.maxCoeff() << std::endl;
+}
+\endcode
+<b> %MatrixBase Example </b><br/><br/>
+Prints the inverse condition number of the given matrix or matrix-expression.
+\code
+template <typename Derived>
+void print_inv_cond(const MatrixBase<Derived>& a)
+{
+  const typename JacobiSVD<typename Derived::PlainObject>::SingularValuesType&
+    sing_vals = a.jacobiSvd().singularValues();
+  std::cout << "inv cond: " << sing_vals(sing_vals.size()-1) / sing_vals(0) << std::endl;
+}
+\endcode
+<b> Multiple templated arguments example </b><br/><br/>
+Calculate the Euclidean distance between two points.
+\code
+template <typename DerivedA,typename DerivedB>
+typename DerivedA::Scalar squaredist(const MatrixBase<DerivedA>& p1,const MatrixBase<DerivedB>& p2)
+{
+  return (p1-p2).squaredNorm();
+}
+\endcode
+Notice that we used two template parameters, one per argument. This permits the function to handle inputs of different types, e.g.,
+\code
+squaredist(v1,2*v2)
+\endcode
+where the first argument \c v1 is a vector and the second argument \c 2*v2 is an expression.
+<br/><br/>
+
+These examples are just intended to give the reader a first impression of how functions can be written which take a plain and constant Matrix or Array argument. They are also intended to give the reader an idea about the most common base classes being the optimal candidates for functions. In the next section we will look in more detail at an example and the different ways it can be implemented, while discussing each implementation's problems and advantages. For the discussion below, Matrix and Array as well as MatrixBase and ArrayBase can be exchanged and all arguments still hold.
+
+
+\section TopicUsingRefClass How to write generic, but non-templated function?
+
+In all the previous examples, the functions had to be template functions. This approach allows to write very generic code, but it is often desirable to write non templated function and still keep some level of genericity to avoid stupid copies of the arguments. The typical example is to write functions accepting both a MatrixXf or a block of a MatrixXf. This exactly the purpose of the Ref class. Here is a simple example:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include function_taking_ref.cpp
+</td>
+<td>
+\verbinclude function_taking_ref.out
+</td></tr></table>
+In the first two calls to inv_cond, no copy occur because the memory layout of the arguments matches the memory layout accepted by Ref<MatrixXf>. However, in the last call, we have a generic expression that will be automatically evaluated into a temporary MatrixXf by the Ref<> object.
+
+A Ref object can also be writable. Here is an example of a function computing the covariance matrix of two input matrices where each row is an observation:
+\code
+void cov(const Ref<const MatrixXf> x, const Ref<const MatrixXf> y, Ref<MatrixXf> C)
+{
+  const float num_observations = static_cast<float>(x.rows());
+  const RowVectorXf x_mean = x.colwise().sum() / num_observations;
+  const RowVectorXf y_mean = y.colwise().sum() / num_observations;
+  C = (x.rowwise() - x_mean).transpose() * (y.rowwise() - y_mean) / num_observations;
+}
+\endcode
+and here are two examples calling cov without any copy:
+\code
+MatrixXf m1, m2, m3
+cov(m1, m2, m3);
+cov(m1.leftCols<3>(), m2.leftCols<3>(), m3.topLeftCorner<3,3>());
+\endcode
+The Ref<> class has two other optional template arguments allowing to control the kind of memory layout that can be accepted without any copy. See the class Ref documentation for the details.
+
+\section TopicPlainFunctionsWorking In which cases do functions taking plain Matrix or Array arguments work?
+
+Without using template functions, and without the Ref class, a naive implementation of the previous cov function might look like this
+\code
+MatrixXf cov(const MatrixXf& x, const MatrixXf& y)
+{
+  const float num_observations = static_cast<float>(x.rows());
+  const RowVectorXf x_mean = x.colwise().sum() / num_observations;
+  const RowVectorXf y_mean = y.colwise().sum() / num_observations;
+  return (x.rowwise() - x_mean).transpose() * (y.rowwise() - y_mean) / num_observations;
+}
+\endcode
+and contrary to what one might think at first, this implementation is fine unless you require a generic implementation that works with double matrices too and unless you do not care about temporary objects. Why is that the case? Where are temporaries involved? How can code as given below compile?
+\code
+MatrixXf x,y,z;
+MatrixXf C = cov(x,y+z);
+\endcode
+In this special case, the example is fine and will be working because both parameters are declared as \e const references. The compiler creates a temporary and evaluates the expression x+z into this temporary. Once the function is processed, the temporary is released and the result is assigned to C.
+
+\b Note: Functions taking \e const references to Matrix (or Array) can process expressions at the cost of temporaries.
+
+
+\section TopicPlainFunctionsFailing In which cases do functions taking a plain Matrix or Array argument fail?
+
+Here, we consider a slightly modified version of the function given above. This time, we do not want to return the result but pass an additional non-const paramter which allows us to store the result. A first naive implementation might look as follows.
+\code
+// Note: This code is flawed!
+void cov(const MatrixXf& x, const MatrixXf& y, MatrixXf& C)
+{
+  const float num_observations = static_cast<float>(x.rows());
+  const RowVectorXf x_mean = x.colwise().sum() / num_observations;
+  const RowVectorXf y_mean = y.colwise().sum() / num_observations;
+  C = (x.rowwise() - x_mean).transpose() * (y.rowwise() - y_mean) / num_observations;
+}
+\endcode
+When trying to execute the following code
+\code
+MatrixXf C = MatrixXf::Zero(3,6);
+cov(x,y, C.block(0,0,3,3));
+\endcode
+the compiler will fail, because it is not possible to convert the expression returned by \c MatrixXf::block() into a non-const \c MatrixXf&. This is the case because the compiler wants to protect you from writing your result to a temporary object. In this special case this protection is not intended -- we want to write to a temporary object. So how can we overcome this problem? 
+
+The solution which is preferred at the moment is based on a little \em hack. One needs to pass a const reference to the matrix and internally the constness needs to be cast away. The correct implementation for C98 compliant compilers would be
+\code
+template <typename Derived, typename OtherDerived>
+void cov(const MatrixBase<Derived>& x, const MatrixBase<Derived>& y, MatrixBase<OtherDerived> const & C)
+{
+  typedef typename Derived::Scalar Scalar;
+  typedef typename internal::plain_row_type<Derived>::type RowVectorType;
+
+  const Scalar num_observations = static_cast<Scalar>(x.rows());
+
+  const RowVectorType x_mean = x.colwise().sum() / num_observations;
+  const RowVectorType y_mean = y.colwise().sum() / num_observations;
+
+  const_cast< MatrixBase<OtherDerived>& >(C) =
+    (x.rowwise() - x_mean).transpose() * (y.rowwise() - y_mean) / num_observations;
+}
+\endcode
+The implementation above does now not only work with temporary expressions but it also allows to use the function with matrices of arbitrary floating point scalar types.
+
+\b Note: The const cast hack will only work with templated functions. It will not work with the MatrixXf implementation because it is not possible to cast a Block expression to a Matrix reference!
+
+
+
+\section TopicResizingInGenericImplementations How to resize matrices in generic implementations?
+
+One might think we are done now, right? This is not completely true because in order for our covariance function to be generically applicable, we want the follwing code to work
+\code
+MatrixXf x = MatrixXf::Random(100,3);
+MatrixXf y = MatrixXf::Random(100,3);
+MatrixXf C;
+cov(x, y, C);
+\endcode
+This is not the case anymore, when we are using an implementation taking MatrixBase as a parameter. In general, %Eigen supports automatic resizing but it is not possible to do so on expressions. Why should resizing of a matrix Block be allowed? It is a reference to a sub-matrix and we definitely don't want to resize that. So how can we incorporate resizing if we cannot resize on MatrixBase? The solution is to resize the derived object as in this implementation.
+\code
+template <typename Derived, typename OtherDerived>
+void cov(const MatrixBase<Derived>& x, const MatrixBase<Derived>& y, MatrixBase<OtherDerived> const & C_)
+{
+  typedef typename Derived::Scalar Scalar;
+  typedef typename internal::plain_row_type<Derived>::type RowVectorType;
+
+  const Scalar num_observations = static_cast<Scalar>(x.rows());
+
+  const RowVectorType x_mean = x.colwise().sum() / num_observations;
+  const RowVectorType y_mean = y.colwise().sum() / num_observations;
+
+  MatrixBase<OtherDerived>& C = const_cast< MatrixBase<OtherDerived>& >(C_);
+  
+  C.derived().resize(x.cols(),x.cols()); // resize the derived object
+  C = (x.rowwise() - x_mean).transpose() * (y.rowwise() - y_mean) / num_observations;
+}
+\endcode
+This implementation is now working for parameters being expressions and for parameters being matrices and having the wrong size. Resizing the expressions does not do any harm in this case unless they actually require resizing. That means, passing an expression with the wrong dimensions will result in a run-time error (in debug mode only) while passing expressions of the correct size will just work fine.
+
+\b Note: In the above discussion the terms Matrix and Array and MatrixBase and ArrayBase can be exchanged and all arguments still hold.
+
+\section TopicSummary Summary
+
+  - To summarize, the implementation of functions taking non-writable (const referenced) objects is not a big issue and does not lead to problematic situations in terms of compiling and running your program. However, a naive implementation is likely to introduce unnecessary temporary objects in your code. In order to avoid evaluating parameters into temporaries, pass them as (const) references to MatrixBase or ArrayBase (so templatize your function).
+
+  - Functions taking writable (non-const) parameters must take const references and cast away constness within the function body.
+
+  - Functions that take as parameters MatrixBase (or ArrayBase) objects, and potentially need to resize them (in the case where they are resizable), must call resize() on the derived class, as returned by derived().

+/** \page TopicWritingEfficientProductExpression Writing efficient matrix product expressions
+
+In general achieving good performance with Eigen does no require any special effort:
+simply write your expressions in the most high level way. This is especially true
+for small fixed size matrices. For large matrices, however, it might be useful to
+take some care when writing your expressions in order to minimize useless evaluations
+and optimize the performance.
+In this page we will give a brief overview of the Eigen's internal mechanism to simplify
+and evaluate complex product expressions, and discuss the current limitations.
+In particular we will focus on expressions matching level 2 and 3 BLAS routines, i.e,
+all kind of matrix products and triangular solvers.
+
+Indeed, in Eigen we have implemented a set of highly optimized routines which are very similar
+to BLAS's ones. Unlike BLAS, those routines are made available to user via a high level and
+natural API. Each of these routines can compute in a single evaluation a wide variety of expressions.
+Given an expression, the challenge is then to map it to a minimal set of routines.
+As explained latter, this mechanism has some limitations, and knowing them will allow
+you to write faster code by making your expressions more Eigen friendly.
+
+\section GEMM General Matrix-Matrix product (GEMM)
+
+Let's start with the most common primitive: the matrix product of general dense matrices.
+In the BLAS world this corresponds to the GEMM routine. Our equivalent primitive can
+perform the following operation:
+\f$ C.noalias() += \alpha op1(A) op2(B) \f$
+where A, B, and C are column and/or row major matrices (or sub-matrices),
+alpha is a scalar value, and op1, op2 can be transpose, adjoint, conjugate, or the identity.
+When Eigen detects a matrix product, it analyzes both sides of the product to extract a
+unique scalar factor alpha, and for each side, its effective storage order, shape, and conjugation states.
+More precisely each side is simplified by iteratively removing trivial expressions such as scalar multiple,
+negation and conjugation. Transpose and Block expressions are not evaluated and they only modify the storage order
+and shape. All other expressions are immediately evaluated.
+For instance, the following expression:
+\code m1.noalias() -= s4 * (s1 * m2.adjoint() * (-(s3*m3).conjugate()*s2))  \endcode
+is automatically simplified to:
+\code m1.noalias() += (s1*s2*conj(s3)*s4) * m2.adjoint() * m3.conjugate() \endcode
+which exactly matches our GEMM routine.
+
+\subsection GEMM_Limitations Limitations
+Unfortunately, this simplification mechanism is not perfect yet and not all expressions which could be
+handled by a single GEMM-like call are correctly detected.

+/** \eigenManualPage InplaceDecomposition Inplace matrix decompositions
+
+Starting from %Eigen 3.3, the LU, Cholesky, and QR decompositions can operate \em inplace, that is, directly within the given input matrix.
+This feature is especially useful when dealing with huge matrices, and or when the available memory is very limited (embedded systems).
+
+To this end, the respective decomposition class must be instantiated with a Ref<> matrix type, and the decomposition object must be constructed with the input matrix as argument. As an example, let us consider an inplace LU decomposition with partial pivoting.
+
+Let's start with the basic inclusions, and declaration of a 2x2 matrix \c A:
+
+<table class="example">
+<tr><th>code</th><th>output</th></tr>
+<tr>
+  <td>\snippet TutorialInplaceLU.cpp init
+  </td>
+  <td>\snippet TutorialInplaceLU.out init
+  </td>
+</tr>
+</table>
+
+No surprise here! Then, let's declare our inplace LU object \c lu, and check the content of the matrix \c A:
+
+<table class="example">
+<tr>
+  <td>\snippet TutorialInplaceLU.cpp declaration
+  </td>
+  <td>\snippet TutorialInplaceLU.out declaration
+  </td>
+</tr>
+</table>
+
+Here, the \c lu object computes and stores the \c L and \c U factors within the memory held by the matrix \c A.
+The coefficients of \c A have thus been destroyed during the factorization, and replaced by the L and U factors as one can verify:
+
+<table class="example">
+<tr>
+  <td>\snippet TutorialInplaceLU.cpp matrixLU
+  </td>
+  <td>\snippet TutorialInplaceLU.out matrixLU
+  </td>
+</tr>
+</table>
+
+Then, one can use the \c lu object as usual, for instance to solve the Ax=b problem:
+<table class="example">
+<tr>
+  <td>\snippet TutorialInplaceLU.cpp solve
+  </td>
+  <td>\snippet TutorialInplaceLU.out solve
+  </td>
+</tr>
+</table>
+
+Here, since the content of the original matrix \c A has been lost, we had to declared a new matrix \c A0 to verify the result.
+
+Since the memory is shared between \c A and \c lu, modifying the matrix \c A will make \c lu invalid.
+This can easily be verified by modifying the content of \c A and trying to solve the initial problem again:
+
+<table class="example">
+<tr>
+  <td>\snippet TutorialInplaceLU.cpp modifyA
+  </td>
+  <td>\snippet TutorialInplaceLU.out modifyA
+  </td>
+</tr>
+</table>
+
+Note that there is no shared pointer under the hood, it is the \b responsibility \b of \b the \b user to keep the input matrix \c A in life as long as \c lu is living.
+
+If one wants to update the factorization with the modified A, one has to call the compute method as usual:
+<table class="example">
+<tr>
+  <td>\snippet TutorialInplaceLU.cpp recompute
+  </td>
+  <td>\snippet TutorialInplaceLU.out recompute
+  </td>
+</tr>
+</table>
+
+Note that calling compute does not change the memory which is referenced by the \c lu object. Therefore, if the compute method is called with another matrix \c A1 different than \c A, then the content of \c A1 won't be modified. This is still the content of \c A that will be used to store the L and U factors of the matrix \c A1.
+This can easily be verified as follows:
+<table class="example">
+<tr>
+  <td>\snippet TutorialInplaceLU.cpp recompute_bis0
+ </td>
+  <td>\snippet TutorialInplaceLU.out recompute_bis0
+ </td>
+</tr>
+</table>
+The matrix \c A1 is unchanged, and one can thus solve A1*x=b, and directly check the residual without any copy of \c A1:
+<table class="example">
+<tr>
+  <td>\snippet TutorialInplaceLU.cpp recompute_bis1
+  </td>
+  <td>\snippet TutorialInplaceLU.out recompute_bis1
+ </td>
+</tr>
+</table>
+
+
+Here is the list of matrix decompositions supporting this inplace mechanism:
+
+- class LLT
+- class LDLT
+- class PartialPivLU
+- class FullPivLU
+- class HouseholderQR
+- class ColPivHouseholderQR

+/** \page TopicInsideEigenExample What happens inside Eigen, on a simple example
+
+\eigenAutoToc
+
+<hr>
+
+
+Consider the following example program:
+
+\code
+#include<Eigen/Core>
+
+int main()
+{
+  int size = 50;
+  // VectorXf is a vector of floats, with dynamic size.
+  Eigen::VectorXf u(size), v(size), w(size);
+  u = v + w;
+}
+\endcode
+
+The goal of this page is to understand how Eigen compiles it, assuming that SSE2 vectorization is enabled (GCC option -msse2).
+
+\section WhyInteresting Why it's interesting
+
+Maybe you think, that the above example program is so simple, that compiling it shouldn't involve anything interesting. So before starting, let us explain what is nontrivial in compiling it correctly -- that is, producing optimized code -- so that the complexity of Eigen, that we'll explain here, is really useful.
+
+Look at the line of code
+\code
+  u = v + w;   //   (*)
+\endcode
+
+The first important thing about compiling it, is that the arrays should be traversed only once, like
+\code
+  for(int i = 0; i < size; i++) u[i] = v[i] + w[i];
+\endcode
+The problem is that if we make a naive C++ library where the VectorXf class has an operator+ returning a VectorXf, then the line of code (*) will amount to:
+\code
+  VectorXf tmp = v + w;
+  VectorXf u = tmp;
+\endcode
+Obviously, the introduction of the temporary \a tmp here is useless. It has a very bad effect on performance, first because the creation of \a tmp requires a dynamic memory allocation in this context, and second as there are now two for loops:
+\code
+  for(int i = 0; i < size; i++) tmp[i] = v[i] + w[i];
+  for(int i = 0; i < size; i++) u[i] = tmp[i];
+\endcode
+Traversing the arrays twice instead of once is terrible for performance, as it means that we do many redundant memory accesses.
+
+The second important thing about compiling the above program, is to make correct use of SSE2 instructions. Notice that Eigen also supports AltiVec and that all the discussion that we make here applies also to AltiVec.
+
+SSE2, like AltiVec, is a set of instructions allowing to perform computations on packets of 128 bits at once. Since a float is 32 bits, this means that SSE2 instructions can handle 4 floats at once. This means that, if correctly used, they can make our computation go up to 4x faster.
+
+However, in the above program, we have chosen size=50, so our vectors consist of 50 float's, and 50 is not a multiple of 4. This means that we cannot hope to do all of that computation using SSE2 instructions. The second best thing, to which we should aim, is to handle the 48 first coefficients with SSE2 instructions, since 48 is the biggest multiple of 4 below 50, and then handle separately, without SSE2, the 49th and 50th coefficients. Something like this:
+
+\code
+  for(int i = 0; i < 4*(size/4); i+=4) u.packet(i)  = v.packet(i) + w.packet(i);
+  for(int i = 4*(size/4); i < size; i++) u[i] = v[i] + w[i];
+\endcode
+
+So let us look line by line at our example program, and let's follow Eigen as it compiles it.
+
+\section ConstructingVectors Constructing vectors
+
+Let's analyze the first line:
+
+\code
+  Eigen::VectorXf u(size), v(size), w(size);
+\endcode
+
+First of all, VectorXf is the following typedef:
+\code
+  typedef Matrix<float, Dynamic, 1> VectorXf;
+\endcode
+
+The class template Matrix is declared in src/Core/util/ForwardDeclarations.h with 6 template parameters, but the last 3 are automatically determined by the first 3. So you don't need to worry about them for now. Here, Matrix\<float, Dynamic, 1\> means a matrix of floats, with a dynamic number of rows and 1 column.
+
+The Matrix class inherits a base class, MatrixBase. Don't worry about it, for now it suffices to say that MatrixBase is what unifies matrices/vectors and all the expressions types -- more on that below.
+
+When we do
+\code
+  Eigen::VectorXf u(size);
+\endcode
+the constructor that is called is Matrix::Matrix(int), in src/Core/Matrix.h. Besides some assertions, all it does is to construct the \a m_storage member, which is of type DenseStorage\<float, Dynamic, Dynamic, 1\>.
+
+You may wonder, isn't it overengineering to have the storage in a separate class? The reason is that the Matrix class template covers all kinds of matrices and vector: both fixed-size and dynamic-size. The storage method is not the same in these two cases. For fixed-size, the matrix coefficients are stored as a plain member array. For dynamic-size, the coefficients will be stored as a pointer to a dynamically-allocated array. Because of this, we need to abstract storage away from the Matrix class. That's DenseStorage.
+
+Let's look at this constructor, in src/Core/DenseStorage.h. You can see that there are many partial template specializations of DenseStorages here, treating separately the cases where dimensions are Dynamic or fixed at compile-time. The partial specialization that we are looking at is:
+\code
+template<typename T, int _Cols> class DenseStorage<T, Dynamic, Dynamic, _Cols>
+\endcode
+
+Here, the constructor called is DenseStorage::DenseStorage(int size, int rows, int columns)
+with size=50, rows=50, columns=1.
+
+Here is this constructor:
+\code
+inline DenseStorage(int size, int rows, int) : m_data(internal::aligned_new<T>(size)), m_rows(rows) {}
+\endcode
+
+Here, the \a m_data member is the actual array of coefficients of the matrix. As you see, it is dynamically allocated. Rather than calling new[] or malloc(), as you can see, we have our own internal::aligned_new defined in src/Core/util/Memory.h. What it does is that if vectorization is enabled, then it uses a platform-specific call to allocate a 128-bit-aligned array, as that is very useful for vectorization with both SSE2 and AltiVec. If vectorization is disabled, it amounts to the standard new[].
+
+As you can see, the constructor also sets the \a m_rows member to \a size. Notice that there is no \a m_columns member: indeed, in this partial specialization of DenseStorage, we know the number of columns at compile-time, since the _Cols template parameter is different from Dynamic. Namely, in our case, _Cols is 1, which is to say that our vector is just a matrix with 1 column. Hence, there is no need to store the number of columns as a runtime variable.
+
+When you call VectorXf::data() to get the pointer to the array of coefficients, it returns DenseStorage::data() which returns the \a m_data member.
+
+When you call VectorXf::size() to get the size of the vector, this is actually a method in the base class MatrixBase. It determines that the vector is a column-vector, since ColsAtCompileTime==1 (this comes from the template parameters in the typedef VectorXf). It deduces that the size is the number of rows, so it returns VectorXf::rows(), which returns DenseStorage::rows(), which returns the \a m_rows member, which was set to \a size by the constructor.
+
+\section ConstructionOfSumXpr Construction of the sum expression
+
+Now that our vectors are constructed, let's move on to the next line:
+
+\code
+u = v + w;
+\endcode
+
+The executive summary is that operator+ returns a "sum of vectors" expression, but doesn't actually perform the computation. It is the operator=, whose call occurs thereafter, that does the computation.
+
+Let us now see what Eigen does when it sees this:
+
+\code
+v + w
+\endcode
+
+Here, v and w are of type VectorXf, which is a typedef for a specialization of Matrix (as we explained above), which is a subclass of MatrixBase. So what is being called is
+
+\code
+MatrixBase::operator+(const MatrixBase&)
+\endcode
+
+The return type of this operator is
+\code
+CwiseBinaryOp<internal::scalar_sum_op<float>, VectorXf, VectorXf>
+\endcode
+The CwiseBinaryOp class is our first encounter with an expression template. As we said, the operator+ doesn't by itself perform any computation, it just returns an abstract "sum of vectors" expression. Since there are also "difference of vectors" and "coefficient-wise product of vectors" expressions, we unify them all as "coefficient-wise binary operations", which we abbreviate as "CwiseBinaryOp". "Coefficient-wise" means that the operations is performed coefficient by coefficient. "binary" means that there are two operands -- we are adding two vectors with one another.
+
+Now you might ask, what if we did something like
+
+\code
+v + w + u;
+\endcode
+
+The first v + w would return a CwiseBinaryOp as above, so in order for this to compile, we'd need to define an operator+ also in the class CwiseBinaryOp... at this point it starts looking like a nightmare: are we going to have to define all operators in each of the expression classes (as you guessed, CwiseBinaryOp is only one of many) ? This looks like a dead end!
+
+The solution is that CwiseBinaryOp itself, as well as Matrix and all the other expression types, is a subclass of MatrixBase. So it is enough to define once and for all the operators in class MatrixBase.
+
+Since MatrixBase is the common base class of different subclasses, the aspects that depend on the subclass must be abstracted from MatrixBase. This is called polymorphism.
+
+The classical approach to polymorphism in C++ is by means of virtual functions. This is dynamic polymorphism. Here we don't want dynamic polymorphism because the whole design of Eigen is based around the assumption that all the complexity, all the abstraction, gets resolved at compile-time. This is crucial: if the abstraction can't get resolved at compile-time, Eigen's compile-time optimization mechanisms become useless, not to mention that if that abstraction has to be resolved at runtime it'll incur an overhead by itself.
+
+Here, what we want is to have a single class MatrixBase as the base of many subclasses, in such a way that each MatrixBase object (be it a matrix, or vector, or any kind of expression) knows at compile-time (as opposed to run-time) of which particular subclass it is an object (i.e. whether it is a matrix, or an expression, and what kind of expression).
+
+The solution is the <a href="http://en.wikipedia.org/wiki/Curiously_Recurring_Template_Pattern">Curiously Recurring Template Pattern</a>. Let's do the break now. Hopefully you can read this wikipedia page during the break if needed, but it won't be allowed during the exam.
+
+In short, MatrixBase takes a template parameter \a Derived. Whenever we define a subclass Subclass, we actually make Subclass inherit MatrixBase\<Subclass\>. The point is that different subclasses inherit different MatrixBase types. Thanks to this, whenever we have an object of a subclass, and we call on it some MatrixBase method, we still remember even from inside the MatrixBase method which particular subclass we're talking about.
+
+This means that we can put almost all the methods and operators in the base class MatrixBase, and have only the bare minimum in the subclasses. If you look at the subclasses in Eigen, like for instance the CwiseBinaryOp class, they have very few methods. There are coeff() and sometimes coeffRef() methods for access to the coefficients, there are rows() and cols() methods returning the number of rows and columns, but there isn't much more than that. All the meat is in MatrixBase, so it only needs to be coded once for all kinds of expressions, matrices, and vectors.
+
+So let's end this digression and come back to the piece of code from our example program that we were currently analyzing,
+
+\code
+v + w
+\endcode
+
+Now that MatrixBase is a good friend, let's write fully the prototype of the operator+ that gets called here (this code is from src/Core/MatrixBase.h):
+
+\code
+template<typename Derived>
+class MatrixBase
+{
+  // ...
+
+  template<typename OtherDerived>
+  const CwiseBinaryOp<internal::scalar_sum_op<typename internal::traits<Derived>::Scalar>, Derived, OtherDerived>
+  operator+(const MatrixBase<OtherDerived> &other) const;
+
+  // ...
+};
+\endcode
+
+Here of course, \a Derived and \a OtherDerived are VectorXf.
+
+As we said, CwiseBinaryOp is also used for other operations such as substration, so it takes another template parameter determining the operation that will be applied to coefficients. This template parameter is a functor, that is, a class in which we have an operator() so it behaves like a function. Here, the functor used is internal::scalar_sum_op. It is defined in src/Core/Functors.h.
+
+Let us now explain the internal::traits here. The internal::scalar_sum_op class takes one template parameter: the type of the numbers to handle. Here of course we want to pass the scalar type (a.k.a. numeric type) of VectorXf, which is \c float. How do we determine which is the scalar type of \a Derived ? Throughout Eigen, all matrix and expression types define a typedef \a Scalar which gives its scalar type. For example, VectorXf::Scalar is a typedef for \c float. So here, if life was easy, we could find the numeric type of \a Derived as just
+\code
+typename Derived::Scalar
+\endcode
+Unfortunately, we can't do that here, as the compiler would complain that the type Derived hasn't yet been defined. So we use a workaround: in src/Core/util/ForwardDeclarations.h, we declared (not defined!) all our subclasses, like Matrix, and we also declared the following class template:
+\code
+template<typename T> struct internal::traits;
+\endcode
+In src/Core/Matrix.h, right \em before the definition of class Matrix, we define a partial specialization of internal::traits for T=Matrix\<any template parameters\>. In this specialization of internal::traits, we define the Scalar typedef. So when we actually define Matrix, it is legal to refer to "typename internal::traits\<Matrix\>::Scalar".
+
+Anyway, we have declared our operator+. In our case, where \a Derived and \a OtherDerived are VectorXf, the above declaration amounts to:
+\code
+class MatrixBase<VectorXf>
+{
+  // ...
+
+  const CwiseBinaryOp<internal::scalar_sum_op<float>, VectorXf, VectorXf>
+  operator+(const MatrixBase<VectorXf> &other) const;
+
+  // ...
+};
+\endcode
+
+Let's now jump to src/Core/CwiseBinaryOp.h to see how it is defined. As you can see there, all it does is to return a CwiseBinaryOp object, and this object is just storing references to the left-hand-side and right-hand-side expressions -- here, these are the vectors \a v and \a w. Well, the CwiseBinaryOp object is also storing an instance of the (empty) functor class, but you shouldn't worry about it as that is a minor implementation detail.
+
+Thus, the operator+ hasn't performed any actual computation. To summarize, the operation \a v + \a w just returned an object of type CwiseBinaryOp which did nothing else than just storing references to \a v and \a w.
+
+\section Assignment The assignment
+
+At this point, the expression \a v + \a w has finished evaluating, so, in the process of compiling the line of code
+\code
+u = v + w;
+\endcode
+we now enter the operator=.
+
+What operator= is being called here? The vector u is an object of class VectorXf, i.e. Matrix. In src/Core/Matrix.h, inside the definition of class Matrix, we see this:
+\code
+    template<typename OtherDerived>
+    inline Matrix& operator=(const MatrixBase<OtherDerived>& other)
+    {
+      eigen_assert(m_storage.data()!=0 && "you cannot use operator= with a non initialized matrix (instead use set()");
+      return Base::operator=(other.derived());
+    }
+\endcode
+Here, Base is a typedef for MatrixBase\<Matrix\>. So, what is being called is the operator= of MatrixBase. Let's see its prototype in src/Core/MatrixBase.h:
+\code
+    template<typename OtherDerived>
+    Derived& operator=(const MatrixBase<OtherDerived>& other);
+\endcode
+Here, \a Derived is VectorXf (since u is a VectorXf) and \a OtherDerived is CwiseBinaryOp. More specifically, as explained in the previous section, \a OtherDerived is:
+\code
+CwiseBinaryOp<internal::scalar_sum_op<float>, VectorXf, VectorXf>
+\endcode
+So the full prototype of the operator= being called is:
+\code
+VectorXf& MatrixBase<VectorXf>::operator=(const MatrixBase<CwiseBinaryOp<internal::scalar_sum_op<float>, VectorXf, VectorXf> > & other);
+\endcode
+This operator= literally reads "copying a sum of two VectorXf's into another VectorXf".
+
+Let's now look at the implementation of this operator=. It resides in the file src/Core/Assign.h.
+
+What we can see there is:
+\code
+template<typename Derived>
+template<typename OtherDerived>
+inline Derived& MatrixBase<Derived>
+  ::operator=(const MatrixBase<OtherDerived>& other)
+{
+  return internal::assign_selector<Derived,OtherDerived>::run(derived(), other.derived());
+}
+\endcode
+
+OK so our next task is to understand internal::assign_selector :)
+
+Here is its declaration (all that is still in the same file src/Core/Assign.h)
+\code
+template<typename Derived, typename OtherDerived,
+         bool EvalBeforeAssigning = int(OtherDerived::Flags) & EvalBeforeAssigningBit,
+         bool NeedToTranspose = Derived::IsVectorAtCompileTime
+                && OtherDerived::IsVectorAtCompileTime
+                && int(Derived::RowsAtCompileTime) == int(OtherDerived::ColsAtCompileTime)
+                && int(Derived::ColsAtCompileTime) == int(OtherDerived::RowsAtCompileTime)
+                && int(Derived::SizeAtCompileTime) != 1>
+struct internal::assign_selector;
+\endcode
+
+So internal::assign_selector takes 4 template parameters, but the 2 last ones are automatically determined by the 2 first ones.
+
+EvalBeforeAssigning is here to enforce the EvalBeforeAssigningBit. As explained <a href="TopicLazyEvaluation.html">here</a>, certain expressions have this flag which makes them automatically evaluate into temporaries before assigning them to another expression. This is the case of the Product expression, in order to avoid strange aliasing effects when doing "m = m * m;" However, of course here our CwiseBinaryOp expression doesn't have the EvalBeforeAssigningBit: we said since the beginning that we didn't want a temporary to be introduced here. So if you go to src/Core/CwiseBinaryOp.h, you'll see that the Flags in internal::traits\<CwiseBinaryOp\> don't include the EvalBeforeAssigningBit. The Flags member of CwiseBinaryOp is then imported from the internal::traits by the EIGEN_GENERIC_PUBLIC_INTERFACE macro. Anyway, here the template parameter EvalBeforeAssigning has the value \c false.
+
+NeedToTranspose is here for the case where the user wants to copy a row-vector into a column-vector. We allow this as a special exception to the general rule that in assignments we require the dimesions to match. Anyway, here both the left-hand and right-hand sides are column vectors, in the sense that ColsAtCompileTime is equal to 1. So NeedToTranspose is \c false too.
+
+So, here we are in the partial specialization:
+\code
+internal::assign_selector<Derived, OtherDerived, false, false>
+\endcode
+
+Here's how it is defined:
+\code
+template<typename Derived, typename OtherDerived>
+struct internal::assign_selector<Derived,OtherDerived,false,false> {
+  static Derived& run(Derived& dst, const OtherDerived& other) { return dst.lazyAssign(other.derived()); }
+};
+\endcode
+
+OK so now our next job is to understand how lazyAssign works :)
+
+\code
+template<typename Derived>
+template<typename OtherDerived>
+inline Derived& MatrixBase<Derived>
+  ::lazyAssign(const MatrixBase<OtherDerived>& other)
+{
+  EIGEN_STATIC_ASSERT_SAME_MATRIX_SIZE(Derived,OtherDerived)
+  eigen_assert(rows() == other.rows() && cols() == other.cols());
+  internal::assign_impl<Derived, OtherDerived>::run(derived(),other.derived());
+  return derived();
+}
+\endcode
+
+What do we see here? Some assertions, and then the only interesting line is:
+\code
+  internal::assign_impl<Derived, OtherDerived>::run(derived(),other.derived());
+\endcode
+
+OK so now we want to know what is inside internal::assign_impl.
+
+Here is its declaration:
+\code
+template<typename Derived1, typename Derived2,
+         int Vectorization = internal::assign_traits<Derived1, Derived2>::Vectorization,
+         int Unrolling = internal::assign_traits<Derived1, Derived2>::Unrolling>
+struct internal::assign_impl;
+\endcode
+Again, internal::assign_selector takes 4 template parameters, but the 2 last ones are automatically determined by the 2 first ones.
+
+These two parameters \a Vectorization and \a Unrolling are determined by a helper class internal::assign_traits. Its job is to determine which vectorization strategy to use (that is \a Vectorization) and which unrolling strategy to use (that is \a Unrolling).
+
+We'll not enter into the details of how these strategies are chosen (this is in the implementation of internal::assign_traits at the top of the same file). Let's just say that here \a Vectorization has the value \a LinearVectorization, and \a Unrolling has the value \a NoUnrolling (the latter is obvious since our vectors have dynamic size so there's no way to unroll the loop at compile-time).
+
+So the partial specialization of internal::assign_impl that we're looking at is:
+\code
+internal::assign_impl<Derived1, Derived2, LinearVectorization, NoUnrolling>
+\endcode
+
+Here is how it's defined:
+\code
+template<typename Derived1, typename Derived2>
+struct internal::assign_impl<Derived1, Derived2, LinearVectorization, NoUnrolling>
+{
+  static void run(Derived1 &dst, const Derived2 &src)
+  {
+    const int size = dst.size();
+    const int packetSize = internal::packet_traits<typename Derived1::Scalar>::size;
+    const int alignedStart = internal::assign_traits<Derived1,Derived2>::DstIsAligned ? 0
+                           : internal::first_aligned(&dst.coeffRef(0), size);
+    const int alignedEnd = alignedStart + ((size-alignedStart)/packetSize)*packetSize;
+
+    for(int index = 0; index < alignedStart; index++)
+      dst.copyCoeff(index, src);
+
+    for(int index = alignedStart; index < alignedEnd; index += packetSize)
+    {
+      dst.template copyPacket<Derived2, Aligned, internal::assign_traits<Derived1,Derived2>::SrcAlignment>(index, src);
+    }
+
+    for(int index = alignedEnd; index < size; index++)
+      dst.copyCoeff(index, src);
+  }
+};
+\endcode
+
+Here's how it works. \a LinearVectorization means that the left-hand and right-hand side expression can be accessed linearly i.e. you can refer to their coefficients by one integer \a index, as opposed to having to refer to its coefficients by two integers \a row, \a column.
+
+As we said at the beginning, vectorization works with blocks of 4 floats. Here, \a PacketSize is 4.
+
+There are two potential problems that we need to deal with:
+\li first, vectorization works much better if the packets are 128-bit-aligned. This is especially important for write access. So when writing to the coefficients of \a dst, we want to group these coefficients by packets of 4 such that each of these packets is 128-bit-aligned. In general, this requires to skip a few coefficients at the beginning of \a dst. This is the purpose of \a alignedStart. We then copy these first few coefficients one by one, not by packets. However, in our case, the \a dst expression is a VectorXf and remember that in the construction of the vectors we allocated aligned arrays. Thanks to \a DstIsAligned, Eigen remembers that without having to do any runtime check, so \a alignedStart is zero and this part is avoided altogether.
+\li second, the number of coefficients to copy is not in general a multiple of \a packetSize. Here, there are 50 coefficients to copy and \a packetSize is 4. So we'll have to copy the last 2 coefficients one by one, not by packets. Here, \a alignedEnd is 48.
+
+Now come the actual loops.
+
+First, the vectorized part: the 48 first coefficients out of 50 will be copied by packets of 4:
+\code
+  for(int index = alignedStart; index < alignedEnd; index += packetSize)
+  {
+    dst.template copyPacket<Derived2, Aligned, internal::assign_traits<Derived1,Derived2>::SrcAlignment>(index, src);
+  }
+\endcode
+
+What is copyPacket? It is defined in src/Core/Coeffs.h:
+\code
+template<typename Derived>
+template<typename OtherDerived, int StoreMode, int LoadMode>
+inline void MatrixBase<Derived>::copyPacket(int index, const MatrixBase<OtherDerived>& other)
+{
+  eigen_internal_assert(index >= 0 && index < size());
+  derived().template writePacket<StoreMode>(index,
+    other.derived().template packet<LoadMode>(index));
+}
+\endcode
+
+OK, what are writePacket() and packet() here?
+
+First, writePacket() here is a method on the left-hand side VectorXf. So we go to src/Core/Matrix.h to look at its definition:
+\code
+template<int StoreMode>
+inline void writePacket(int index, const PacketScalar& x)
+{
+  internal::pstoret<Scalar, PacketScalar, StoreMode>(m_storage.data() + index, x);
+}
+\endcode
+Here, \a StoreMode is \a #Aligned, indicating that we are doing a 128-bit-aligned write access, \a PacketScalar is a type representing a "SSE packet of 4 floats" and internal::pstoret is a function writing such a packet in memory. Their definitions are architecture-specific, we find them in src/Core/arch/SSE/PacketMath.h:
+
+The line in src/Core/arch/SSE/PacketMath.h that determines the PacketScalar type (via a typedef in Matrix.h) is:
+\code
+template<> struct internal::packet_traits<float>  { typedef __m128  type; enum {size=4}; };
+\endcode
+Here, __m128 is a SSE-specific type. Notice that the enum \a size here is what was used to define \a packetSize above.
+
+And here is the implementation of internal::pstoret:
+\code
+template<> inline void internal::pstore(float*  to, const __m128&  from) { _mm_store_ps(to, from); }
+\endcode
+Here, __mm_store_ps is a SSE-specific intrinsic function, representing a single SSE instruction. The difference between internal::pstore and internal::pstoret is that internal::pstoret is a dispatcher handling both the aligned and unaligned cases, you find its definition in src/Core/GenericPacketMath.h:
+\code
+template<typename Scalar, typename Packet, int LoadMode>
+inline void internal::pstoret(Scalar* to, const Packet& from)
+{
+  if(LoadMode == Aligned)
+    internal::pstore(to, from);
+  else
+    internal::pstoreu(to, from);
+}
+\endcode
+
+OK, that explains how writePacket() works. Now let's look into the packet() call. Remember that we are analyzing this line of code inside copyPacket():
+\code
+derived().template writePacket<StoreMode>(index,
+    other.derived().template packet<LoadMode>(index));
+\endcode
+
+Here, \a other is our sum expression \a v + \a w. The .derived() is just casting from MatrixBase to the subclass which here is CwiseBinaryOp. So let's go to src/Core/CwiseBinaryOp.h:
+\code
+class CwiseBinaryOp
+{
+  // ...
+    template<int LoadMode>
+    inline PacketScalar packet(int index) const
+    {
+      return m_functor.packetOp(m_lhs.template packet<LoadMode>(index), m_rhs.template packet<LoadMode>(index));
+    }
+};
+\endcode
+Here, \a m_lhs is the vector \a v, and \a m_rhs is the vector \a w. So the packet() function here is Matrix::packet(). The template parameter \a LoadMode is \a #Aligned. So we're looking at
+\code
+class Matrix
+{
+  // ...
+    template<int LoadMode>
+    inline PacketScalar packet(int index) const
+    {
+      return internal::ploadt<Scalar, LoadMode>(m_storage.data() + index);
+    }
+};
+\endcode
+We let you look up the definition of internal::ploadt in GenericPacketMath.h and the internal::pload in src/Core/arch/SSE/PacketMath.h. It is very similar to the above for internal::pstore.
+
+Let's go back to CwiseBinaryOp::packet(). Once the packets from the vectors \a v and \a w have been returned, what does this function do? It calls m_functor.packetOp() on them. What is m_functor? Here we must remember what particular template specialization of CwiseBinaryOp we're dealing with:
+\code
+CwiseBinaryOp<internal::scalar_sum_op<float>, VectorXf, VectorXf>
+\endcode
+So m_functor is an object of the empty class internal::scalar_sum_op<float>. As we mentioned above, don't worry about why we constructed an object of this empty class at all -- it's an implementation detail, the point is that some other functors need to store member data.
+
+Anyway, internal::scalar_sum_op is defined in src/Core/Functors.h:
+\code
+template<typename Scalar> struct internal::scalar_sum_op EIGEN_EMPTY_STRUCT {
+  inline const Scalar operator() (const Scalar& a, const Scalar& b) const { return a + b; }
+  template<typename PacketScalar>
+  inline const PacketScalar packetOp(const PacketScalar& a, const PacketScalar& b) const
+  { return internal::padd(a,b); }
+};
+\endcode
+As you can see, all what packetOp() does is to call internal::padd on the two packets. Here is the definition of internal::padd from src/Core/arch/SSE/PacketMath.h:
+\code
+template<> inline __m128  internal::padd(const __m128&  a, const __m128&  b) { return _mm_add_ps(a,b); }
+\endcode
+Here, _mm_add_ps is a SSE-specific intrinsic function, representing a single SSE instruction.
+
+To summarize, the loop
+\code
+  for(int index = alignedStart; index < alignedEnd; index += packetSize)
+  {
+    dst.template copyPacket<Derived2, Aligned, internal::assign_traits<Derived1,Derived2>::SrcAlignment>(index, src);
+  }
+\endcode
+has been compiled to the following code: for \a index going from 0 to the 11 ( = 48/4 - 1), read the i-th packet (of 4 floats) from the vector v and the i-th packet from the vector w using two __mm_load_ps SSE instructions, then add them together using a __mm_add_ps instruction, then store the result using a __mm_store_ps instruction.
+
+There remains the second loop handling the last few (here, the last 2) coefficients:
+\code
+  for(int index = alignedEnd; index < size; index++)
+    dst.copyCoeff(index, src);
+\endcode
+However, it works just like the one we just explained, it is just simpler because there is no SSE vectorization involved here. copyPacket() becomes copyCoeff(), packet() becomes coeff(), writePacket() becomes coeffRef(). If you followed us this far, you can probably understand this part by yourself.
+
+We see that all the C++ abstraction of Eigen goes away during compilation and that we indeed are precisely controlling which assembly instructions we emit. Such is the beauty of C++! Since we have such precise control over the emitted assembly instructions, but such complex logic to choose the right instructions, we can say that Eigen really behaves like an optimizing compiler. If you prefer, you could say that Eigen behaves like a script for the compiler. In a sense, C++ template metaprogramming is scripting the compiler -- and it's been shown that this scripting language is Turing-complete. See <a href="http://en.wikipedia.org/wiki/Template_metaprogramming"> Wikipedia</a>.

+/** \eigenManualPage LeastSquares Solving linear least squares systems
+
+This page describes how to solve linear least squares systems using %Eigen. An overdetermined system
+of equations, say \a Ax = \a b, has no solutions. In this case, it makes sense to search for the
+vector \a x which is closest to being a solution, in the sense that the difference \a Ax - \a b is
+as small as possible. This \a x is called the least square solution (if the Euclidean norm is used).
+
+The three methods discussed on this page are the SVD decomposition, the QR decomposition and normal
+equations. Of these, the SVD decomposition is generally the most accurate but the slowest, normal
+equations is the fastest but least accurate, and the QR decomposition is in between.
+
+\eigenAutoToc
+
+
+\section LeastSquaresSVD Using the SVD decomposition
+
+The \link BDCSVD::solve() solve() \endlink method in the BDCSVD class can be directly used to
+solve linear squares systems. It is not enough to compute only the singular values (the default for
+this class); you also need the singular vectors but the thin SVD decomposition suffices for
+computing least squares solutions:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+  <td>\include TutorialLinAlgSVDSolve.cpp </td>
+  <td>\verbinclude TutorialLinAlgSVDSolve.out </td>
+</tr>
+</table>
+
+This is example from the page \link TutorialLinearAlgebra Linear algebra and decompositions \endlink.
+
+
+\section LeastSquaresQR Using the QR decomposition
+
+The solve() method in QR decomposition classes also computes the least squares solution. There are
+three QR decomposition classes: HouseholderQR (no pivoting, so fast but unstable),
+ColPivHouseholderQR (column pivoting, thus a bit slower but more accurate) and FullPivHouseholderQR
+(full pivoting, so slowest and most stable). Here is an example with column pivoting:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+  <td>\include LeastSquaresQR.cpp </td>
+  <td>\verbinclude LeastSquaresQR.out </td>
+</tr>
+</table>
+
+
+\section LeastSquaresNormalEquations Using normal equations
+
+Finding the least squares solution of \a Ax = \a b is equivalent to solving the normal equation
+<i>A</i><sup>T</sup><i>Ax</i> = <i>A</i><sup>T</sup><i>b</i>. This leads to the following code
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+  <td>\include LeastSquaresNormalEquations.cpp </td>
+  <td>\verbinclude LeastSquaresNormalEquations.out </td>
+</tr>
+</table>
+
+If the matrix \a A is ill-conditioned, then this is not a good method, because the condition number
+of <i>A</i><sup>T</sup><i>A</i> is the square of the condition number of \a A. This means that you
+lose twice as many digits using normal equation than if you use the other methods.

+\section TopicSetting The setting
+
+A circulant matrix is a matrix where each column is the same as the
+column to the left, except that it is cyclically shifted downwards.
+For example, here is a 4-by-4 circulant matrix:
+\f[ \begin{bmatrix} 
+    1 & 8 & 4 & 2 \\ 
+    2 & 1 & 8 & 4 \\
+    4 & 2 & 1 & 8 \\
+    8 & 4 & 2 & 1
+\end{bmatrix} \f]
+A circulant matrix is uniquely determined by its first column. We wish
+to write a function \c makeCirculant which, given the first column,
+returns an expression representing the circulant matrix.
+
+For simplicity, we restrict the \c makeCirculant function to dense
+matrices. It may make sense to also allow arrays, or sparse matrices,
+but we will not do so here. We also do not want to support
+vectorization.
+
+
+\section TopicPreamble Getting started
+
+We will present the file implementing the \c makeCirculant function
+part by part. We start by including the appropriate header files and
+forward declaring the expression class, which we will call
+\c Circulant. The \c makeCirculant function will return an object of
+this type. The class \c Circulant is in fact a class template; the
+template argument \c ArgType refers to the type of the vector passed
+to the \c makeCirculant function.
+
+\include make_circulant.cpp.preamble

+
+\section TopicTraits The traits class
+
+For every expression class \c X, there should be a traits class 
+\c Traits<X> in the \c Eigen::internal namespace containing
+information about \c X known as compile time.
+
+As explained in \ref TopicSetting, we designed the \c Circulant
+expression class to refer to dense matrices. The entries of the
+circulant matrix have the same type as the entries of the vector
+passed to the \c makeCirculant function. The type used to index the
+entries is also the same. Again for simplicity, we will only return
+column-major matrices. Finally, the circulant matrix is a square
+matrix (number of rows equals number of columns), and the number of
+rows equals the number of rows of the column vector passed to the
+\c makeCirculant function. If this is a dynamic-size vector, then the
+size of the circulant matrix is not known at compile-time.
+
+This leads to the following code:
+
+\include make_circulant.cpp.traits
+
+
+\section TopicExpression The expression class
+
+The next step is to define the expression class itself. In our case,
+we want to inherit from \c MatrixBase in order to expose the interface
+for dense matrices. In the constructor, we check that we are passed a
+column vector (see \ref TopicAssertions) and we store the vector from
+which we are going to build the circulant matrix in the member
+variable \c m_arg. Finally, the expression class should compute the
+size of the corresponding circulant matrix. As explained above, this
+is a square matrix with as many columns as the vector used to
+construct the matrix.
+
+\b TO \b DO: What about the \c Nested typedef? It seems to be
+necessary; is this only temporary?
+
+\include make_circulant.cpp.expression
+
+
+\section TopicEvaluator The evaluator
+
+The last big fragment implements the evaluator for the \c Circulant
+expression. The evaluator computes the entries of the circulant
+matrix; this is done in the \c .coeff() member function. The entries
+are computed by finding the corresponding entry of the vector from
+which the circulant matrix is constructed. Getting this entry may
+actually be non-trivial when the circulant matrix is constructed from
+a vector which is given by a complicated expression, so we use the
+evaluator which corresponds to the vector.
+
+The \c CoeffReadCost constant records the cost of computing an entry
+of the circulant matrix; we ignore the index computation and say that
+this is the same as the cost of computing an entry of the vector from
+which the circulant matrix is constructed.
+
+In the constructor, we save the evaluator for the column vector which
+defined the circulant matrix. We also save the size of that vector;
+remember that we can query an expression object to find the size but
+not the evaluator. 
+
+\include make_circulant.cpp.evaluator
+
+
+\section TopicEntry The entry point
+
+After all this, the \c makeCirculant function is very simple. It
+simply creates an expression object and returns it.
+
+\include make_circulant.cpp.entry
+
+
+\section TopicMain A simple main function for testing
+
+Finally, a short \c main function that shows how the \c makeCirculant
+function can be called.
+
+\include make_circulant.cpp.main
+
+If all the fragments are combined, the following output is produced,
+showing that the program works as expected:
+
+\include make_circulant.out

+/** \eigenManualPage TopicPassingByValue Passing Eigen objects by value to functions
+
+Passing objects by value is almost always a very bad idea in C++, as this means useless copies, and one should pass them by reference instead.
+
+With Eigen, this is even more important: passing \ref TopicFixedSizeVectorizable "fixed-size vectorizable Eigen objects" by value is not only inefficient, it can be illegal or make your program crash! And the reason is that these Eigen objects have alignment modifiers that aren't respected when they are passed by value.
+
+So for example, a function like this, where v is passed by value:
+
+\code
+void my_function(Eigen::Vector2d v);
+\endcode
+
+needs to be rewritten as follows, passing v by reference:
+
+\code
+void my_function(const Eigen::Vector2d& v);
+\endcode
+
+Likewise if you have a class having a Eigen object as member:
+
+\code
+struct Foo
+{
+  Eigen::Vector2d v;
+};
+void my_function(Foo v);
+\endcode
+
+This function also needs to be rewritten like this:
+\code
+void my_function(const Foo& v);
+\endcode
+
+Note that on the other hand, there is no problem with functions that return objects by value.

+\section TopicPitfalls_auto_keyword C++11 and the auto keyword
+
+In short: do not use the auto keywords with Eigen's expressions, unless you are 100% sure about what you are doing. In particular, do not use the auto keyword as a replacement for a Matrix<> type. Here is an example:
+
+\code
+MatrixXd A, B;
+auto C = A*B;
+for(...) { ... w = C * v;  ...}
+\endcode
+
+In this example, the type of C is not a MatrixXd but an abstract expression representing a matrix product and storing references to A and B. Therefore, the product of A*B will be carried out multiple times, once per iteration of the for loop. Moreover, if the coefficients of A or B change during the iteration, then C will evaluate to different values.
+
+Here is another example leading to a segfault:
+\code
+auto C = ((A+B).eval()).transpose();
+// do something with C
+\endcode
+The problem is that eval() returns a temporary object (in this case a MatrixXd) which is then referenced by the Transpose<> expression. However, this temporary is deleted right after the first line, and there the C expression reference a dead object. The same issue might occur when sub expressions are automatically evaluated by Eigen as in the following example:
+\code
+VectorXd u, v;
+auto C = u + (A*v).normalized();
+// do something with C
+\endcode
+where the normalized() method has to evaluate the expensive product A*v to avoid evaluating it twice. On the other hand, the following example is perfectly fine:
+\code
+auto C = (u + (A*v).normalized()).eval();
+\endcode
+In this case, C will be a regular VectorXd object.

+/** \page TopicPreprocessorDirectives Preprocessor directives
+
+You can control some aspects of %Eigen by defining the preprocessor tokens using \c \#define. These macros
+should be defined before any %Eigen headers are included. Often they are best set in the project options.
+
+This page lists the preprocessor tokens recognized by %Eigen.
+
+\eigenAutoToc
+
+
+\section TopicPreprocessorDirectivesMajor Macros with major effects
+
+These macros have a major effect and typically break the API (Application Programming Interface) and/or the
+ABI (Application Binary Interface). This can be rather dangerous: if parts of your program are compiled with
+one option, and other parts (or libraries that you use) are compiled with another option, your program may
+fail to link or exhibit subtle bugs. Nevertheless, these options can be useful for people who know what they
+are doing.
+
+ - \b EIGEN2_SUPPORT and \b EIGEN2_SUPPORT_STAGEnn_xxx are disabled starting from the 3.3 release.
+   Defining one of these will raise a compile-error. If you need to compile Eigen2 code,
+   <a href="http://eigen.tuxfamily.org/index.php?title=Eigen2">check this site</a>.
+ - \b EIGEN_DEFAULT_DENSE_INDEX_TYPE - the type for column and row indices in matrices, vectors and array
+   (DenseBase::Index). Set to \c std::ptrdiff_t by default.
+ - \b EIGEN_DEFAULT_IO_FORMAT - the IOFormat to use when printing a matrix if no %IOFormat is specified.
+   Defaults to the %IOFormat constructed by the default constructor IOFormat::IOFormat().
+ - \b EIGEN_INITIALIZE_MATRICES_BY_ZERO - if defined, all entries of newly constructed matrices and arrays are
+   initialized to zero, as are new entries in matrices and arrays after resizing. Not defined by default.
+   \warning The unary (resp. binary) constructor of \c 1x1 (resp. \c 2x1 or \c 1x2) fixed size matrices is
+   always interpreted as an initialization constructor where the argument(s) are the coefficient values
+   and not the sizes. For instance, \code Vector2d v(2,1); \endcode will create a vector with coeficients [2,1],
+   and \b not a \c 2x1 vector initialized with zeros (i.e., [0,0]). If such cases might occur, then it is
+   recommended to use the default constructor with a explicit call to resize:
+   \code
+   Matrix<?,SizeAtCompileTime,1> v;
+   v.resize(size);
+   Matrix<?,RowsAtCompileTime,ColsAtCompileTime> m;
+   m.resize(rows,cols);
+   \endcode
+ - \b EIGEN_INITIALIZE_MATRICES_BY_NAN - if defined, all entries of newly constructed matrices and arrays are
+   initialized to NaN, as are new entries in matrices and arrays after resizing. This option is especially
+   useful for debugging purpose, though a memory tool like <a href="http://valgrind.org/">valgrind</a> is
+   preferable. Not defined by default.
+   \warning See the documentation of \c EIGEN_INITIALIZE_MATRICES_BY_ZERO for a discussion on a limitations
+   of these macros when applied to \c 1x1, \c 1x2, and \c 2x1 fixed-size matrices.
+ - \b EIGEN_NO_AUTOMATIC_RESIZING - if defined, the matrices (or arrays) on both sides of an assignment 
+   <tt>a = b</tt> have to be of the same size; otherwise, %Eigen automatically resizes \c a so that it is of
+   the correct size. Not defined by default.
+
+
+\section TopicPreprocessorDirectivesCppVersion C++ standard features
+
+By default, %Eigen strive to automatically detect and enable langage features at compile-time based on
+the information provided by the compiler.
+
+ - \b EIGEN_MAX_CPP_VER - disables usage of C++ features requiring a version greater than EIGEN_MAX_CPP_VER.
+   Possible values are: 03, 11, 14, 17, etc. If not defined (the default), %Eigen enables all features supported
+   by the compiler.
+
+Individual features can be explicitly enabled or disabled by defining the following token to 0 or 1 respectively.
+For instance, one might limit the C++ version to C++03 by defining EIGEN_MAX_CPP_VER=03, but still enable C99 math
+functions by defining EIGEN_HAS_C99_MATH=1.
+
+ - \b EIGEN_HAS_C99_MATH - controls the usage of C99 math functions such as erf, erfc, lgamma, etc.
+   Automatic detection disabled if EIGEN_MAX_CPP_VER<11.
+ - \b EIGEN_HAS_CXX11_MATH - controls the implementation of some functions such as round, logp1, isinf, isnan, etc.
+   Automatic detection disabled if EIGEN_MAX_CPP_VER<11.
+ - \b EIGEN_HAS_RVALUE_REFERENCES - defines whetehr rvalue references are supported
+   Automatic detection disabled if EIGEN_MAX_CPP_VER<11.
+ - \b EIGEN_HAS_STD_RESULT_OF - defines whether std::result_of is supported
+   Automatic detection disabled if EIGEN_MAX_CPP_VER<11.
+ - \b EIGEN_HAS_VARIADIC_TEMPLATES - defines whether variadic templates are supported
+   Automatic detection disabled if EIGEN_MAX_CPP_VER<11.
+ - \b EIGEN_HAS_CONSTEXPR - defines whether relaxed const expression are supported
+   Automatic detection disabled if EIGEN_MAX_CPP_VER<14.
+ - \b EIGEN_HAS_CXX11_CONTAINERS - defines whether STL's containers follows C++11 specifications
+   Automatic detection disabled if EIGEN_MAX_CPP_VER<11.
+ - \b EIGEN_HAS_CXX11_NOEXCEPT - defines whether noexcept is supported
+   Automatic detection disabled if EIGEN_MAX_CPP_VER<11.
+
+\section TopicPreprocessorDirectivesAssertions Assertions
+
+The %Eigen library contains many assertions to guard against programming errors, both at compile time and at
+run time. However, these assertions do cost time and can thus be turned off.
+
+ - \b EIGEN_NO_DEBUG - disables %Eigen's assertions if defined. Not defined by default, unless the
+   \c NDEBUG macro is defined (this is a standard C++ macro which disables all asserts). 
+ - \b EIGEN_NO_STATIC_ASSERT - if defined, compile-time static assertions are replaced by runtime assertions; 
+   this saves compilation time. Not defined by default.
+ - \b eigen_assert - macro with one argument that is used inside %Eigen for assertions. By default, it is
+   basically defined to be \c assert, which aborts the program if the assertion is violated. Redefine this
+   macro if you want to do something else, like throwing an exception.
+ - \b EIGEN_MPL2_ONLY - disable non MPL2 compatible features, or in other words disable the features which
+   are still under the LGPL.
+
+
+\section TopicPreprocessorDirectivesPerformance Alignment, vectorization and performance tweaking
+
+ - \b \c EIGEN_MALLOC_ALREADY_ALIGNED - Can be set to 0 or 1 to tell whether default system \c malloc already
+   returns aligned buffers. In not defined, then this information is automatically deduced from the compiler
+   and system preprocessor tokens.
+ - \b \c EIGEN_MAX_ALIGN_BYTES - Must be a power of two, or 0. Defines an upper bound on the memory boundary in bytes on which dynamically and statically allocated data may be aligned by %Eigen. If not defined, a default value is automatically computed based on architecture, compiler, and OS.
+ This option is typically used to enforce binary compatibility between code/libraries compiled with different SIMD options. For instance, one may compile AVX code and enforce ABI compatibility with existing SSE code by defining \c EIGEN_MAX_ALIGN_BYTES=16. In the other way round, since by default AVX implies 32 bytes alignment for best performance, one can compile SSE code to be ABI compatible with AVX code by defining \c EIGEN_MAX_ALIGN_BYTES=32.
+ - \b \c EIGEN_MAX_STATIC_ALIGN_BYTES - Same as \c EIGEN_MAX_ALIGN_BYTES but for statically allocated data only. By default, if only  \c EIGEN_MAX_ALIGN_BYTES is defined, then \c EIGEN_MAX_STATIC_ALIGN_BYTES == \c EIGEN_MAX_ALIGN_BYTES, otherwise a default value is automatically computed based on architecture, compiler, and OS (can be smaller than the default value of EIGEN_MAX_ALIGN_BYTES on architectures that do not support stack alignment).
+ Let us emphasize that \c EIGEN_MAX_*_ALIGN_BYTES define only a diserable upper bound. In practice data is aligned to largest power-of-two common divisor of \c EIGEN_MAX_STATIC_ALIGN_BYTES and the size of the data, such that memory is not wasted.
+ - \b \c EIGEN_DONT_PARALLELIZE - if defined, this disables multi-threading. This is only relevant if you enabled OpenMP.
+   See \ref TopicMultiThreading for details.
+ - \b EIGEN_DONT_VECTORIZE - disables explicit vectorization when defined. Not defined by default, unless 
+   alignment is disabled by %Eigen's platform test or the user defining \c EIGEN_DONT_ALIGN.
+ - \b \c EIGEN_UNALIGNED_VECTORIZE - disables/enables vectorization with unaligned stores. Default is 1 (enabled).
+   If set to 0 (disabled), then expression for which the destination cannot be aligned are not vectorized (e.g., unaligned
+   small fixed size vectors or matrices)
+ - \b \c EIGEN_FAST_MATH - enables some optimizations which might affect the accuracy of the result. This currently
+   enables the SSE vectorization of sin() and cos(), and speedups sqrt() for single precision. Defined to 1 by default.
+   Define it to 0 to disable.
+ - \b \c EIGEN_UNROLLING_LIMIT - defines the size of a loop to enable meta unrolling. Set it to zero to disable
+   unrolling. The size of a loop here is expressed in %Eigen's own notion of "number of FLOPS", it does not
+   correspond to the number of iterations or the number of instructions. The default is value 100.
+ - \b \c EIGEN_STACK_ALLOCATION_LIMIT - defines the maximum bytes for a buffer to be allocated on the stack. For internal
+   temporary buffers, dynamic memory allocation is employed as a fall back. For fixed-size matrices or arrays, exceeding
+   this threshold raises a compile time assertion. Use 0 to set no limit. Default is 128 KB.
+ - \b \c EIGEN_STRONG_INLINE - This macro is used to qualify critical functions and methods that we expect the compiler to inline.
+   By default it is defined to \c __forceinline for MSVC and ICC, and to \c inline for other compilers. A tipical usage is to
+   define it to \c inline for MSVC users wanting faster compilation times, at the risk of performance degradations in some rare
+   cases for which MSVC inliner fails to do a good job.
+
+
+ - \c EIGEN_DONT_ALIGN - Deprecated, it is a synonym for \c EIGEN_MAX_ALIGN_BYTES=0. It disables alignment completely. %Eigen will not try to align its objects and does not expect that any objects passed to it are aligned. This will turn off vectorization if \b EIGEN_UNALIGNED_VECTORIZE=1. Not defined by default.
+ - \c EIGEN_DONT_ALIGN_STATICALLY - Deprecated, it is a synonym for \c EIGEN_MAX_STATIC_ALIGN_BYTES=0. It disables alignment of arrays on the stack. Not defined by default, unless \c EIGEN_DONT_ALIGN is defined.
+
+
+\section TopicPreprocessorDirectivesPlugins Plugins
+
+It is possible to add new methods to many fundamental classes in %Eigen by writing a plugin. As explained in
+the section \ref TopicCustomizing_Plugins, the plugin is specified by defining a \c EIGEN_xxx_PLUGIN macro. The
+following macros are supported; none of them are defined by default.
+
+ - \b EIGEN_ARRAY_PLUGIN - filename of plugin for extending the Array class.
+ - \b EIGEN_ARRAYBASE_PLUGIN - filename of plugin for extending the ArrayBase class.
+ - \b EIGEN_CWISE_PLUGIN - filename of plugin for extending the Cwise class.
+ - \b EIGEN_DENSEBASE_PLUGIN - filename of plugin for extending the DenseBase class.
+ - \b EIGEN_DYNAMICSPARSEMATRIX_PLUGIN - filename of plugin for extending the DynamicSparseMatrix class.

+ - \b EIGEN_MAPBASE_PLUGIN - filename of plugin for extending the MapBase class.
+ - \b EIGEN_QUATERNION_PLUGIN - filename of plugin for extending the Quaternion class.
+ - \b EIGEN_QUATERNIONBASE_PLUGIN - filename of plugin for extending the QuaternionBase class.
+ - \b EIGEN_SPARSEMATRIX_PLUGIN - filename of plugin for extending the SparseMatrix class.
+ - \b EIGEN_SPARSEMATRIXBASE_PLUGIN - filename of plugin for extending the SparseMatrixBase class.
+ - \b EIGEN_SPARSEVECTOR_PLUGIN - filename of plugin for extending the SparseVector class.
+ - \b EIGEN_TRANSFORM_PLUGIN - filename of plugin for extending the Transform class.
+ - \b EIGEN_FUNCTORS_PLUGIN - filename of plugin for adding new functors and specializations of functor_traits.
+
+
+\section TopicPreprocessorDirectivesDevelopers Macros for Eigen developers
+
+These macros are mainly meant for people developing %Eigen and for testing purposes. Even though, they might be useful for power users and the curious for debugging and testing purpose, they \b should \b not \b be \b used by real-word code.
+
+ - \b EIGEN_DEFAULT_TO_ROW_MAJOR - when defined, the default storage order for matrices becomes row-major
+   instead of column-major. Not defined by default.
+ - \b EIGEN_INTERNAL_DEBUGGING - if defined, enables assertions in %Eigen's internal routines. This is useful
+   for debugging %Eigen itself. Not defined by default.
+ - \b EIGEN_NO_MALLOC - if defined, any request from inside the %Eigen to allocate memory from the heap
+   results in an assertion failure. This is useful to check that some routine does not allocate memory
+   dynamically. Not defined by default.
+ - \b EIGEN_RUNTIME_NO_MALLOC - if defined, a new switch is introduced which can be turned on and off by
+   calling <tt>set_is_malloc_allowed(bool)</tt>. If malloc is not allowed and %Eigen tries to allocate memory
+   dynamically anyway, an assertion failure results. Not defined by default.

+\section QuickRef_Types Array, matrix and vector types
+
+
+\b Recall: Eigen provides two kinds of dense objects: mathematical matrices and vectors which are both represented by the template class Matrix, and general 1D and 2D arrays represented by the template class Array:
+\code
+typedef Matrix<Scalar, RowsAtCompileTime, ColsAtCompileTime, Options> MyMatrixType;
+typedef Array<Scalar, RowsAtCompileTime, ColsAtCompileTime, Options> MyArrayType;
+\endcode
+
+\li \c Scalar is the scalar type of the coefficients (e.g., \c float, \c double, \c bool, \c int, etc.).
+\li \c RowsAtCompileTime and \c ColsAtCompileTime are the number of rows and columns of the matrix as known at compile-time or \c Dynamic.
+\li \c Options can be \c ColMajor or \c RowMajor, default is \c ColMajor. (see class Matrix for more options)
+
+All combinations are allowed: you can have a matrix with a fixed number of rows and a dynamic number of columns, etc. The following are all valid:
+\code
+Matrix<double, 6, Dynamic>                  // Dynamic number of columns (heap allocation)

+The following coefficient-wise operators are available for all kind of expressions (matrices, vectors, and arrays), and for both real or complex scalar types:
+

+Some coefficient-wise operators are readily available for for matrices and vectors through the following cwise* methods:
+<table class="manual">
+<tr><th>Matrix API \matrixworld</th><th>Via Array conversions</th></tr>
+<tr><td>\code
+mat1.cwiseMin(mat2)         mat1.cwiseMin(scalar)

+mat1.array() == mat2.array()      mat1.array() == scalar
+mat1.array() != mat2.array()
+\endcode</td></tr>
+</table>
+The main difference between the two API is that the one based on cwise* methods returns an expression in the matrix world,
+while the second one (based on .array()) returns an array expression.
+Recall that .array() has no cost, it only changes the available API and interpretation of the data.
+
+It is also very simple to apply any user defined function \c foo using DenseBase::unaryExpr together with <a href="http://en.cppreference.com/w/cpp/utility/functional/ptr_fun">std::ptr_fun</a> (c++03), <a href="http://en.cppreference.com/w/cpp/utility/functional/ref">std::ref</a> (c++11), or <a href="http://en.cppreference.com/w/cpp/language/lambda">lambdas</a> (c++11):
+\code
+mat1.unaryExpr(std::ptr_fun(foo));
+mat1.unaryExpr(std::ref(foo));
+mat1.unaryExpr([](double x) { return foo(x); });

+\section QuickRef_Reductions Reductions
+
+Eigen provides several reduction methods such as:
+\link DenseBase::minCoeff() minCoeff() \endlink, \link DenseBase::maxCoeff() maxCoeff() \endlink,
+\link DenseBase::sum() sum() \endlink, \link DenseBase::prod() prod() \endlink,
+\link MatrixBase::trace() trace() \endlink \matrixworld,
+\link MatrixBase::norm() norm() \endlink \matrixworld, \link MatrixBase::squaredNorm() squaredNorm() \endlink \matrixworld,
+\link DenseBase::all() all() \endlink, and \link DenseBase::any() any() \endlink.
+All reduction operations can be done matrix-wise,
+\link DenseBase::colwise() column-wise \endlink or
+\link DenseBase::rowwise() row-wise \endlink. Usage example:
+<table class="manual">
+<tr><td rowspan="3" style="border-right-style:dashed;vertical-align:middle">\code
+      5 3 1
+mat = 2 7 8

+<tr style="vertical-align:middle"><td>\code mat.rowwise().minCoeff(); \endcode</td><td>\code
+1
+2
+4
+\endcode</td></tr>
+</table>
+
+Special versions of \link DenseBase::minCoeff(IndexType*,IndexType*) const minCoeff \endlink and \link DenseBase::maxCoeff(IndexType*,IndexType*) const maxCoeff \endlink:
+\code
+int i, j;
+s = vector.minCoeff(&i);        // s == vector[i]
+s = matrix.maxCoeff(&i, &j);    // s == matrix(i,j)
+\endcode
+Typical use cases of all() and any():
+\code
+if((array1 > 0).all()) ...      // if all coefficients of array1 are greater than 0 ...
+if((array1 < array2).any()) ... // if there exist a pair i,j such that array1(i,j) < array2(i,j) ...

+\note The .triangularView() template member function requires the \c template keyword if it is used on an
+object of a type that depends on a template parameter; see \ref TopicTemplateKeyword for details.

+/** \page GettingStarted Getting started
+
+\eigenAutoToc
+
+This is a very short guide on how to get started with Eigen. It has a dual purpose. It serves as a minimal introduction to the Eigen library for people who want to start coding as soon as possible. You can also read this page as the first part of the Tutorial, which explains the library in more detail; in this case you will continue with \ref TutorialMatrixClass.
+
+\section GettingStartedInstallation How to "install" Eigen?
+
+In order to use Eigen, you just need to download and extract Eigen's source code (see <a href="http://eigen.tuxfamily.org/index.php?title=Main_Page#Download">the wiki</a> for download instructions). In fact, the header files in the \c Eigen subdirectory are the only files required to compile programs using Eigen. The header files are the same for all platforms. It is not necessary to use CMake or install anything.
+
+
+\section GettingStartedFirstProgram A simple first program
+
+Here is a rather simple program to get you started.
+
+\include QuickStart_example.cpp
+
+We will explain the program after telling you how to compile it.
+
+
+\section GettingStartedCompiling Compiling and running your first program
+
+There is no library to link to. The only thing that you need to keep in mind when compiling the above program is that the compiler must be able to find the Eigen header files. The directory in which you placed Eigen's source code must be in the include path. With GCC you use the -I option to achieve this, so you can compile the program with a command like this:
+
+\code g++ -I /path/to/eigen/ my_program.cpp -o my_program \endcode
+
+On Linux or Mac OS X, another option is to symlink or copy the Eigen folder into /usr/local/include/. This way, you can compile the program with:
+
+\code g++ my_program.cpp -o my_program \endcode
+
+When you run the program, it produces the following output:
+
+\include QuickStart_example.out
+
+
+\section GettingStartedExplanation Explanation of the first program
+
+The Eigen header files define many types, but for simple applications it may be enough to use only the \c MatrixXd type. This represents a matrix of arbitrary size (hence the \c X in \c MatrixXd), in which every entry is a \c double (hence the \c d in \c MatrixXd). See the \ref QuickRef_Types "quick reference guide" for an overview of the different types you can use to represent a matrix.
+
+The \c Eigen/Dense header file defines all member functions for the MatrixXd type and related types (see also the \ref QuickRef_Headers "table of header files"). All classes and functions defined in this header file (and other Eigen header files) are in the \c Eigen namespace. 
+
+The first line of the \c main function declares a variable of type \c MatrixXd and specifies that it is a matrix with 2 rows and 2 columns (the entries are not initialized). The statement <tt>m(0,0) = 3</tt> sets the entry in the top-left corner to 3. You need to use round parentheses to refer to entries in the matrix. As usual in computer science, the index of the first index is 0, as opposed to the convention in mathematics that the first index is 1.
+
+The following three statements sets the other three entries. The final line outputs the matrix \c m to the standard output stream.
+
+
+\section GettingStartedExample2 Example 2: Matrices and vectors
+
+Here is another example, which combines matrices with vectors. Concentrate on the left-hand program for now; we will talk about the right-hand program later.
+
+<table class="manual">
+<tr><th>Size set at run time:</th><th>Size set at compile time:</th></tr>
+<tr><td>
+\include QuickStart_example2_dynamic.cpp
+</td>
+<td>
+\include QuickStart_example2_fixed.cpp
+</td></tr></table>
+
+The output is as follows:
+
+\include QuickStart_example2_dynamic.out
+
+
+\section GettingStartedExplanation2 Explanation of the second example
+
+The second example starts by declaring a 3-by-3 matrix \c m which is initialized using the \link DenseBase::Random(Index,Index) Random() \endlink method with random values between -1 and 1. The next line applies a linear mapping such that the values are between 10 and 110. The function call \link DenseBase::Constant(Index,Index,const Scalar&) MatrixXd::Constant\endlink(3,3,1.2) returns a 3-by-3 matrix expression having all coefficients equal to 1.2. The rest is standard arithmetics.
+
+The next line of the \c main function introduces a new type: \c VectorXd. This represents a (column) vector of arbitrary size. Here, the vector \c v is created to contain \c 3 coefficients which are left unitialized. The one but last line uses the so-called comma-initializer, explained in \ref TutorialAdvancedInitialization, to set all coefficients of the vector \c v to be as follows:
+
+\f[
+v =
+\begin{bmatrix}
+  1 \\
+  2 \\
+  3
+\end{bmatrix}.
+\f]
+
+The final line of the program multiplies the matrix \c m with the vector \c v and outputs the result.
+
+Now look back at the second example program. We presented two versions of it. In the version in the left column, the matrix is of type \c MatrixXd which represents matrices of arbitrary size. The version in the right column is similar, except that the matrix is of type \c Matrix3d, which represents matrices of a fixed size (here 3-by-3). Because the type already encodes the size of the matrix, it is not necessary to specify the size in the constructor; compare <tt>MatrixXd m(3,3)</tt> with <tt>Matrix3d m</tt>. Similarly, we have \c VectorXd on the left (arbitrary size) versus \c Vector3d on the right (fixed size). Note that here the coefficients of vector \c v are directly set in the constructor, though the same syntax of the left example could be used too.
+
+The use of fixed-size matrices and vectors has two advantages. The compiler emits better (faster) code because it knows the size of the matrices and vectors. Specifying the size in the type also allows for more rigorous checking at compile-time. For instance, the compiler will complain if you try to multiply a \c Matrix4d (a 4-by-4 matrix) with a \c Vector3d (a vector of size 3). However, the use of many types increases compilation time and the size of the executable. The size of the matrix may also not be known at compile-time. A rule of thumb is to use fixed-size matrices for size 4-by-4 and smaller.
+
+
+\section GettingStartedConclusion Where to go from here?
+
+It's worth taking the time to read the  \ref TutorialMatrixClass "long tutorial".
+
+However if you think you don't need it, you can directly use the classes documentation and our \ref QuickRefPage.

+/** \eigenManualPage TopicSparseSystems Solving Sparse Linear Systems
+In Eigen, there are several methods available to solve linear systems when the coefficient matrix is sparse. Because of the special representation of this class of matrices, special care should be taken in order to get a good performance. See \ref TutorialSparse for a detailed introduction about sparse matrices in Eigen. This page lists the sparse solvers available in Eigen. The main steps that are common to all these linear solvers are introduced as well. Depending on the properties of the matrix, the desired accuracy, the end-user is able to tune those steps in order to improve the performance of its code. Note that it is not required to know deeply what's hiding behind these steps: the last section presents a benchmark routine that can be easily used to get an insight on the performance of all the available solvers.

+
+\section TutorialSparseSolverConcept Sparse solver concept
+
+All these solvers follow the same general concept.
+Here is a typical and general example:
+\code
+#include <Eigen/RequiredModuleName>
+// ...
+SparseMatrix<double> A;
+// fill A
+VectorXd b, x;
+// fill b
+// solve Ax = b
+SolverClassName<SparseMatrix<double> > solver;
+solver.compute(A);
+if(solver.info()!=Success) {
+  // decomposition failed
+  return;
+}
+x = solver.solve(b);
+if(solver.info()!=Success) {
+  // solving failed
+  return;
+}
+// solve for another right hand side:
+x1 = solver.solve(b1);
+\endcode
+
+For \c SPD solvers, a second optional template argument allows to specify which triangular part have to be used, e.g.:
+
+\code
+#include <Eigen/IterativeLinearSolvers>
+
+ConjugateGradient<SparseMatrix<double>, Eigen::Upper> solver;
+x = solver.compute(A).solve(b);
+\endcode
+In the above example, only the upper triangular part of the input matrix A is considered for solving. The opposite triangle might either be empty or contain arbitrary values.
+
+In the case where multiple problems with the same sparsity pattern have to be solved, then the "compute" step can be decomposed as follow:
+\code
+SolverClassName<SparseMatrix<double> > solver;
+solver.analyzePattern(A);   // for this step the numerical values of A are not used
+solver.factorize(A);
+x1 = solver.solve(b1);
+x2 = solver.solve(b2);
+...
+A = ...;                    // modify the values of the nonzeros of A, the nonzeros pattern must stay unchanged
+solver.factorize(A);
+x1 = solver.solve(b1);
+x2 = solver.solve(b2);
+...
+\endcode
+The compute() method is equivalent to calling both analyzePattern() and factorize().
+
+Each solver provides some specific features, such as determinant, access to the factors, controls of the iterations, and so on.
+More details are available in the documentations of the respective classes.
+
+Finally, most of the iterative solvers, can also be used in a \b matrix-free context, see the following \link MatrixfreeSolverExample example \endlink.
+
+\section TheSparseCompute The Compute Step
+In the compute() function, the matrix is generally factorized: LLT for self-adjoint matrices, LDLT for general hermitian matrices, LU for non hermitian matrices and QR for rectangular matrices. These are the results of using direct solvers. For this class of solvers precisely, the compute step is further subdivided into analyzePattern() and factorize(). 
+
+The goal of analyzePattern() is to reorder the nonzero elements of the matrix, such that the factorization step creates less fill-in. This step exploits only the structure of the matrix. Hence, the results of this step can be used for other linear systems where the matrix has the same structure. Note however that sometimes, some external solvers (like SuperLU) require that the values of the matrix are set in this step, for instance to equilibrate the rows and columns of the matrix. In this situation, the results of this step should not be used with other matrices.
+
+Eigen provides a limited set of methods to reorder the matrix in this step, either built-in (COLAMD, AMD) or external (METIS). These methods are set in template parameter list of the solver :
+\code
+DirectSolverClassName<SparseMatrix<double>, OrderingMethod<IndexType> > solver;
+\endcode 
+
+See the \link OrderingMethods_Module OrderingMethods module \endlink for the list of available methods and the associated options. 
+
+In factorize(), the factors of the coefficient matrix are computed. This step should be called each time the values of the matrix change. However, the structural pattern of the matrix should not change between multiple calls. 
+
+For iterative solvers, the compute step is used to eventually setup a preconditioner. For instance, with the ILUT preconditioner, the incomplete factors L and U are computed in this step. Remember that, basically, the goal of the preconditioner is to speedup the convergence of an iterative method by solving a modified linear system where the coefficient matrix has more clustered eigenvalues. For real problems, an iterative solver should always be used with a preconditioner. In Eigen, a preconditioner is  selected by simply adding it as a template parameter to the iterative solver object. 
+\code
+IterativeSolverClassName<SparseMatrix<double>, PreconditionerName<SparseMatrix<double> > solver; 
+\endcode
+The member function preconditioner() returns a read-write reference to the preconditioner 
+ to directly interact with it. See the \link IterativeLinearSolvers_Module Iterative solvers module \endlink and the documentation of each class for the list of available methods.
+
+\section TheSparseSolve The Solve step
+The solve() function computes the solution of the linear systems with one or many right hand sides.
+\code
+X = solver.solve(B);
+\endcode 
+Here, B  can be a vector or a matrix where the columns form the different right hand sides. The solve() function can be called several times as well, for instance when all the right hand sides are not available at once. 
+\code
+x1 = solver.solve(b1);
+// Get the second right hand side b2
+x2 = solver.solve(b2); 
+//  ...
+\endcode
+For direct methods, the solution are computed at the machine precision. Sometimes, the solution need not be too accurate. In this case, the iterative methods are more suitable and the desired accuracy can be set before the solve step using \b setTolerance(). For all the available functions, please, refer to the documentation of the \link IterativeLinearSolvers_Module Iterative solvers module \endlink. 
+
+\section BenchmarkRoutine
+Most of the time, all you need is to know how much time it will take to solve your system, and hopefully, what is the most suitable solver. In Eigen, we provide a benchmark routine that can be used for this purpose. It is very easy to use. In the build directory, navigate to bench/spbench and compile the routine by typing \b make \e spbenchsolver. Run it with --help option to get the list of all available options. Basically, the matrices to test should be in <a href="http://math.nist.gov/MatrixMarket/formats.html">MatrixMarket Coordinate format</a>, and the routine returns the statistics from all available solvers in Eigen.
+
+To export your matrices and right-hand-side vectors in the matrix-market format, you can the the unsupported SparseExtra module:
+\code

+
+<hr>
+
+In this page, we give a quick summary of the main operations available for sparse matrices in the class SparseMatrix. First, it is recommended to read  the introductory tutorial at \ref TutorialSparse. The important point to have in mind when working on sparse matrices is how they are stored : 
+i.e either row major or column major. The default is column major. Most arithmetic operations on sparse matrices will assert that they have the same storage order.

+\section SparseBasicInfos Matrix properties
+Beyond the basic functions rows() and cols(), there are some useful functions that are available to easily get some informations from the matrix. 
+<table class="manual">
+<tr>
+  <td> \code
+  sm1.rows();         // Number of rows
+  sm1.cols();         // Number of columns

+  sm1.squaredNorm();  // Squared norm of the matrix
+  sm1.blueNorm();

+  sm1.isCompressed(); // Check if sm1 is in compressed form
+  ...
+  \endcode </td>
+</tr>
+</table>
+
+\section SparseBasicOps Arithmetic operations
+It is easy to perform arithmetic operations on sparse matrices provided that the dimensions are adequate and that the matrices have the same storage order. Note that the evaluation can always be done in a matrix with a different storage order. In the following, \b sm denotes a sparse matrix, \b dm a dense matrix and \b dv a dense vector.

+
+\eigenAutoToc
+
+\section StlContainers_summary Executive summary
+
+Using STL containers on \ref TopicFixedSizeVectorizable "fixed-size vectorizable Eigen types", or classes having members of such types, requires taking the following two steps:
+
+\li A 16-byte-aligned allocator must be used. Eigen does provide one ready for use: aligned_allocator.
+\li If you want to use the std::vector container, you need to \#include <Eigen/StdVector>.
+
+These issues arise only with \ref TopicFixedSizeVectorizable "fixed-size vectorizable Eigen types" and \ref TopicStructHavingEigenMembers "structures having such Eigen objects as member". For other Eigen types, such as Vector3f or MatrixXd, no special care is needed when using STL containers.
+
+\section allocator Using an aligned allocator
+
+STL containers take an optional template parameter, the allocator type. When using STL containers on \ref TopicFixedSizeVectorizable "fixed-size vectorizable Eigen types", you need tell the container to use an allocator that will always allocate memory at 16-byte-aligned locations. Fortunately, Eigen does provide such an allocator: Eigen::aligned_allocator.
+
+For example, instead of
+\code
+std::map<int, Eigen::Vector4f>
+\endcode
+you need to use
+\code
+std::map<int, Eigen::Vector4f, std::less<int>, 
+         Eigen::aligned_allocator<std::pair<const int, Eigen::Vector4f> > >
+\endcode
+Note that the third parameter "std::less<int>" is just the default value, but we have to include it because we want to specify the fourth parameter, which is the allocator type.
+
+\section StlContainers_vector The case of std::vector
+
+The situation with std::vector was even worse (explanation below) so we had to specialize it for the Eigen::aligned_allocator type. In practice you \b must use the Eigen::aligned_allocator (not another aligned allocator), \b and \#include <Eigen/StdVector>.
+
+Here is an example:
+\code
+#include<Eigen/StdVector>
+/* ... */
+std::vector<Eigen::Vector4f,Eigen::aligned_allocator<Eigen::Vector4f> >
+\endcode
+
+\subsection vector_spec An alternative - specializing std::vector for Eigen types
+
+As an alternative to the recommended approach described above, you have the option to specialize std::vector for Eigen types requiring alignment. 
+The advantage is that you won't need to declare std::vector all over with Eigen::allocator. One drawback on the other hand side is that
+the specialization needs to be defined before all code pieces in which e.g. std::vector<Vector2d> is used. Otherwise, without knowing the specialization
+the compiler will compile that particular instance with the default std::allocator and you program is most likely to crash.
+
+Here is an example:
+\code
+#include<Eigen/StdVector>
+/* ... */
+EIGEN_DEFINE_STL_VECTOR_SPECIALIZATION(Matrix2d)
+std::vector<Eigen::Vector2d>
+\endcode
+
+<span class="note">\b Explanation: The resize() method of std::vector takes a value_type argument (defaulting to value_type()). So with std::vector<Eigen::Vector4f>, some Eigen::Vector4f objects will be passed by value, which discards any alignment modifiers, so a Eigen::Vector4f can be created at an unaligned location. In order to avoid that, the only solution we saw was to specialize std::vector to make it work on a slight modification of, here, Eigen::Vector4f, that is able to deal properly with this situation.

+/** \eigenManualPage TopicStorageOrders Storage orders
+
+There are two different storage orders for matrices and two-dimensional arrays: column-major and row-major.
+This page explains these storage orders and how to specify which one should be used.
+
+\eigenAutoToc
+
+
+\section TopicStorageOrdersIntro Column-major and row-major storage
+
+The entries of a matrix form a two-dimensional grid. However, when the matrix is stored in memory, the entries
+have to somehow be laid out linearly. There are two main ways to do this, by row and by column.
+
+We say that a matrix is stored in \b row-major order if it is stored row by row. The entire first row is
+stored first, followed by the entire second row, and so on. Consider for example the matrix
+
+\f[
+A = \begin{bmatrix}
+8 & 2 & 2 & 9 \\
+9 & 1 & 4 & 4 \\
+3 & 5 & 4 & 5
+\end{bmatrix}.
+\f]
+
+If this matrix is stored in row-major order, then the entries are laid out in memory as follows:
+
+\code 8 2 2 9 9 1 4 4 3 5 4 5 \endcode
+
+On the other hand, a matrix is stored in \b column-major order if it is stored column by column, starting with
+the entire first column, followed by the entire second column, and so on. If the above matrix is stored in
+column-major order, it is laid out as follows:
+
+\code 8 9 3 2 1 5 2 4 4 9 4 5 \endcode
+
+This example is illustrated by the following Eigen code. It uses the PlainObjectBase::data() function, which
+returns a pointer to the memory location of the first entry of the matrix.
+
+<table class="example">
+<tr><th>Example</th><th>Output</th></tr>
+<tr><td>
+\include TopicStorageOrders_example.cpp
+</td>
+<td>
+\verbinclude TopicStorageOrders_example.out
+</td></tr></table>
+
+
+\section TopicStorageOrdersInEigen Storage orders in Eigen
+
+The storage order of a matrix or a two-dimensional array can be set by specifying the \c Options template
+parameter for Matrix or Array. As \ref TutorialMatrixClass explains, the %Matrix class template has six
+template parameters, of which three are compulsory (\c Scalar, \c RowsAtCompileTime and \c ColsAtCompileTime)
+and three are optional (\c Options, \c MaxRowsAtCompileTime and \c MaxColsAtCompileTime). If the \c Options
+parameter is set to \c RowMajor, then the matrix or array is stored in row-major order; if it is set to 
+\c ColMajor, then it is stored in column-major order. This mechanism is used in the above Eigen program to
+specify the storage order.
+
+If the storage order is not specified, then Eigen defaults to storing the entry in column-major. This is also
+the case if one of the convenience typedefs (\c Matrix3f, \c ArrayXXd, etc.) is used.
+
+Matrices and arrays using one storage order can be assigned to matrices and arrays using the other storage
+order, as happens in the above program when \c Arowmajor is initialized using \c Acolmajor. Eigen will reorder
+the entries automatically. More generally, row-major and column-major matrices can be mixed in an expression
+as we want.
+
+
+\section TopicStorageOrdersWhich Which storage order to choose?
+
+So, which storage order should you use in your program? There is no simple answer to this question; it depends
+on your application. Here are some points to keep in mind:
+
+  - Your users may expect you to use a specific storage order. Alternatively, you may use other libraries than
+    Eigen, and these other libraries may expect a certain storage order. In these cases it may be easiest and
+    fastest to use this storage order in your whole program.
+  - Algorithms that traverse a matrix row by row will go faster when the matrix is stored in row-major order
+    because of better data locality. Similarly, column-by-column traversal is faster for column-major
+    matrices. It may be worthwhile to experiment a bit to find out what is faster for your particular
+    application.
+  - The default in Eigen is column-major. Naturally, most of the development and testing of the Eigen library
+    is thus done with column-major matrices. This means that, even though we aim to support column-major and
+    row-major storage orders transparently, the Eigen library may well work best with column-major matrices.

+
+\eigenAutoToc
+
+\section StructHavingEigenMembers_summary Executive Summary
+
+If you define a structure having members of \ref TopicFixedSizeVectorizable "fixed-size vectorizable Eigen types", you must overload its "operator new" so that it generates 16-bytes-aligned pointers. Fortunately, %Eigen provides you with a macro EIGEN_MAKE_ALIGNED_OPERATOR_NEW that does that for you.
+
+\section StructHavingEigenMembers_what What kind of code needs to be changed?
+
+The kind of code that needs to be changed is this:
+
+\code
+class Foo
+{
+  ...
+  Eigen::Vector2d v;
+  ...
+};
+
+...
+
+Foo *foo = new Foo;
+\endcode
+
+In other words: you have a class that has as a member a \ref TopicFixedSizeVectorizable "fixed-size vectorizable Eigen object", and then you dynamically create an object of that class.
+
+\section StructHavingEigenMembers_how How should such code be modified?
+
+Very easy, you just need to put a EIGEN_MAKE_ALIGNED_OPERATOR_NEW macro in a public part of your class, like this:
+
+\code
+class Foo
+{
+  ...
+  Eigen::Vector2d v;
+  ...
+public:
+  EIGEN_MAKE_ALIGNED_OPERATOR_NEW
+};
+
+...
+
+Foo *foo = new Foo;
+\endcode
+
+This macro makes "new Foo" always return an aligned pointer.
+
+If this approach is too intrusive, see also the \ref StructHavingEigenMembers_othersolutions "other solutions".
+
+\section StructHavingEigenMembers_why Why is this needed?
+
+OK let's say that your code looks like this:
+
+\code
+class Foo
+{
+  ...
+  Eigen::Vector2d v;
+  ...
+};
+
+...
+
+Foo *foo = new Foo;
+\endcode
+
+A Eigen::Vector2d consists of 2 doubles, which is 128 bits. Which is exactly the size of a SSE packet, which makes it possible to use SSE for all sorts of operations on this vector. But SSE instructions (at least the ones that %Eigen uses, which are the fast ones) require 128-bit alignment. Otherwise you get a segmentation fault.
+
+For this reason, Eigen takes care by itself to require 128-bit alignment for Eigen::Vector2d, by doing two things:
+\li Eigen requires 128-bit alignment for the Eigen::Vector2d's array (of 2 doubles). With GCC, this is done with a __attribute__ ((aligned(16))).
+\li Eigen overloads the "operator new" of Eigen::Vector2d so it will always return 128-bit aligned pointers.
+
+Thus, normally, you don't have to worry about anything, Eigen handles alignment for you...
+
+... except in one case. When you have a class Foo like above, and you dynamically allocate a new Foo as above, then, since Foo doesn't have aligned "operator new", the returned pointer foo is not necessarily 128-bit aligned.
+
+The alignment attribute of the member v is then relative to the start of the class, foo. If the foo pointer wasn't aligned, then foo->v won't be aligned either!
+
+The solution is to let class Foo have an aligned "operator new", as we showed in the previous section.
+
+\section StructHavingEigenMembers_movetotop Should I then put all the members of Eigen types at the beginning of my class?
+
+That's not required. Since Eigen takes care of declaring 128-bit alignment, all members that need it are automatically 128-bit aligned relatively to the class. So code like this works fine:
+
+\code
+class Foo
+{
+  double x;
+  Eigen::Vector2d v;
+public:
+  EIGEN_MAKE_ALIGNED_OPERATOR_NEW
+};
+\endcode
+
+\section StructHavingEigenMembers_dynamicsize What about dynamic-size matrices and vectors?
+
+Dynamic-size matrices and vectors, such as Eigen::VectorXd, allocate dynamically their own array of coefficients, so they take care of requiring absolute alignment automatically. So they don't cause this issue. The issue discussed here is only with \ref TopicFixedSizeVectorizable  "fixed-size vectorizable matrices and vectors".
+
+\section StructHavingEigenMembers_bugineigen So is this a bug in Eigen?
+
+No, it's not our bug. It's more like an inherent problem of the C++98 language specification, and seems to be taken care of in the upcoming language revision: <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2341.pdf">see this document</a>.
+
+\section StructHavingEigenMembers_conditional What if I want to do this conditionnally (depending on template parameters) ?
+
+For this situation, we offer the macro EIGEN_MAKE_ALIGNED_OPERATOR_NEW_IF(NeedsToAlign). It will generate aligned operators like EIGEN_MAKE_ALIGNED_OPERATOR_NEW if NeedsToAlign is true. It will generate operators with the default alignment if NeedsToAlign is false.
+
+Example:
+
+\code
+template<int n> class Foo
+{
+  typedef Eigen::Matrix<float,n,1> Vector;
+  enum { NeedsToAlign = (sizeof(Vector)%16)==0 };
+  ...
+  Vector v;
+  ...
+public:
+  EIGEN_MAKE_ALIGNED_OPERATOR_NEW_IF(NeedsToAlign)
+};
+
+...
+
+Foo<4> *foo4 = new Foo<4>; // foo4 is guaranteed to be 128bit-aligned
+Foo<3> *foo3 = new Foo<3>; // foo3 has only the system default alignment guarantee
+\endcode
+
+
+\section StructHavingEigenMembers_othersolutions Other solutions
+
+In case putting the EIGEN_MAKE_ALIGNED_OPERATOR_NEW macro everywhere is too intrusive, there exists at least two other solutions.
+
+\subsection othersolutions1 Disabling alignment
+
+The first is to disable alignment requirement for the fixed size members:
+\code
+class Foo
+{
+  ...
+  Eigen::Matrix<double,2,1,Eigen::DontAlign> v;
+  ...
+};
+\endcode
+This has for effect to disable vectorization when using \c v.
+If a function of Foo uses it several times, then it still possible to re-enable vectorization by copying it into an aligned temporary vector:
+\code
+void Foo::bar()
+{
+  Eigen::Vector2d av(v);
+  // use av instead of v
+  ...
+  // if av changed, then do:
+  v = av;
+}
+\endcode
+
+\subsection othersolutions2 Private structure
+
+The second consist in storing the fixed-size objects into a private struct which will be dynamically allocated at the construction time of the main object:
+
+\code
+struct Foo_d
+{
+  EIGEN_MAKE_ALIGNED_OPERATOR_NEW
+  Vector2d v;
+  ...
+};
+
+
+struct Foo {
+  Foo() { init_d(); }
+  ~Foo() { delete d; }
+  void bar()
+  {
+    // use d->v instead of v
+    ...
+  }
+private:
+  void init_d() { d = new Foo_d; }
+  Foo_d* d;
+};
+\endcode
+
+The clear advantage here is that the class Foo remains unchanged regarding alignment issues. The drawback is that a heap allocation will be required whatsoever.

+/** \page TopicTemplateKeyword The template and typename keywords in C++
+
+There are two uses for the \c template and \c typename keywords in C++. One of them is fairly well known
+amongst programmers: to define templates. The other use is more obscure: to specify that an expression refers
+to a template function or a type. This regularly trips up programmers that use the %Eigen library, often
+leading to error messages from the compiler that are difficult to understand, such as "expected expression" or
+"no match for operator<".
+
+\eigenAutoToc
+
+
+\section TopicTemplateKeywordToDefineTemplates Using the template and typename keywords to define templates
+
+The \c template and \c typename keywords are routinely used to define templates. This is not the topic of this
+page as we assume that the reader is aware of this (otherwise consult a C++ book). The following example
+should illustrate this use of the \c template keyword.
+
+\code
+template <typename T>
+bool isPositive(T x)
+{
+    return x > 0;
+}
+\endcode
+
+We could just as well have written <tt>template &lt;class T&gt;</tt>; the keywords \c typename and \c class have the
+same meaning in this context.
+
+
+\section TopicTemplateKeywordExample An example showing the second use of the template keyword
+
+Let us illustrate the second use of the \c template keyword with an example. Suppose we want to write a
+function which copies all entries in the upper triangular part of a matrix into another matrix, while keeping
+the lower triangular part unchanged. A straightforward implementation would be as follows:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include TemplateKeyword_simple.cpp
+</td>
+<td>
+\verbinclude TemplateKeyword_simple.out
+</td></tr></table>
+
+That works fine, but it is not very flexible. First, it only works with dynamic-size matrices of
+single-precision floats; the function \c copyUpperTriangularPart() does not accept static-size matrices or
+matrices with double-precision numbers. Second, if you use an expression such as
+<tt>mat.topLeftCorner(3,3)</tt> as the parameter \c src, then this is copied into a temporary variable of type
+MatrixXf; this copy can be avoided.
+
+As explained in \ref TopicFunctionTakingEigenTypes, both issues can be resolved by making 
+\c copyUpperTriangularPart() accept any object of type MatrixBase. This leads to the following code:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include TemplateKeyword_flexible.cpp
+</td>
+<td>
+\verbinclude TemplateKeyword_flexible.out
+</td></tr></table>
+
+The one line in the body of the function \c copyUpperTriangularPart() shows the second, more obscure use of
+the \c template keyword in C++.  Even though it may look strange, the \c template keywords are necessary
+according to the standard. Without it, the compiler may reject the code with an error message like "no match
+for operator<".
+
+
+\section TopicTemplateKeywordExplanation Explanation
+
+The reason that the \c template keyword is necessary in the last example has to do with the rules for how
+templates are supposed to be compiled in C++. The compiler has to check the code for correct syntax at the
+point where the template is defined, without knowing the actual value of the template arguments (\c Derived1
+and \c Derived2 in the example). That means that the compiler cannot know that <tt>dst.triangularView</tt> is
+a member template and that the following &lt; symbol is part of the delimiter for the template
+parameter. Another possibility would be that <tt>dst.triangularView</tt> is a member variable with the &lt;
+symbol refering to the <tt>operator&lt;()</tt> function. In fact, the compiler should choose the second
+possibility, according to the standard. If <tt>dst.triangularView</tt> is a member template (as in our case),
+the programmer should specify this explicitly with the \c template keyword and write <tt>dst.template
+triangularView</tt>.
+
+The precise rules are rather complicated, but ignoring some subtleties we can summarize them as follows:
+- A <em>dependent name</em> is name that depends (directly or indirectly) on a template parameter. In the
+  example, \c dst is a dependent name because it is of type <tt>MatrixBase&lt;Derived1&gt;</tt> which depends
+  on the template parameter \c Derived1.
+- If the code contains either one of the constructs <tt>xxx.yyy</tt> or <tt>xxx-&gt;yyy</tt> and \c xxx is a
+  dependent name and \c yyy refers to a member template, then the \c template keyword must be used before 
+  \c yyy, leading to <tt>xxx.template yyy</tt> or <tt>xxx-&gt;template yyy</tt>.
+- If the code contains the construct <tt>xxx::yyy</tt> and \c xxx is a dependent name and \c yyy refers to a
+  member typedef, then the \c typename keyword must be used before the whole construct, leading to
+  <tt>typename xxx::yyy</tt>.
+
+As an example where the \c typename keyword is required, consider the following code in \ref TutorialSparse
+for iterating over the non-zero entries of a sparse matrix type:
+
+\code
+SparseMatrixType mat(rows,cols);
+for (int k=0; k<mat.outerSize(); ++k)
+  for (SparseMatrixType::InnerIterator it(mat,k); it; ++it)
+  {
+    /* ... */
+  }
+\endcode
+
+If \c SparseMatrixType depends on a template parameter, then the \c typename keyword is required:
+
+\code
+template <typename T>
+void iterateOverSparseMatrix(const SparseMatrix<T>& mat;
+{
+  for (int k=0; k<m1.outerSize(); ++k)
+    for (typename SparseMatrix<T>::InnerIterator it(mat,k); it; ++it)
+    {
+      /* ... */
+    }
+}
+\endcode
+
+

+/** \eigenManualPage TopicAliasing Aliasing
+
+In %Eigen, aliasing refers to assignment statement in which the same matrix (or array or vector) appears on the
+left and on the right of the assignment operators. Statements like <tt>mat = 2 * mat;</tt> or <tt>mat =
+mat.transpose();</tt> exhibit aliasing. The aliasing in the first example is harmless, but the aliasing in the
+second example leads to unexpected results. This page explains what aliasing is, when it is harmful, and what
+to do about it.
+
+\eigenAutoToc
+
+
+\section TopicAliasingExamples Examples
+
+Here is a simple example exhibiting aliasing:
+
+<table class="example">
+<tr><th>Example</th><th>Output</th></tr>
+<tr><td>
+\include TopicAliasing_block.cpp
+</td>
+<td>
+\verbinclude TopicAliasing_block.out
+</td></tr></table>
+
+The output is not what one would expect. The problem is the assignment
+\code
+mat.bottomRightCorner(2,2) = mat.topLeftCorner(2,2);
+\endcode
+This assignment exhibits aliasing: the coefficient \c mat(1,1) appears both in the block
+<tt>mat.bottomRightCorner(2,2)</tt> on the left-hand side of the assignment and the block
+<tt>mat.topLeftCorner(2,2)</tt> on the right-hand side. After the assignment, the (2,2) entry in the bottom
+right corner should have the value of \c mat(1,1) before the assignment, which is 5. However, the output shows
+that \c mat(2,2) is actually 1. The problem is that %Eigen uses lazy evaluation (see 
+\ref TopicEigenExpressionTemplates) for <tt>mat.topLeftCorner(2,2)</tt>. The result is similar to
+\code
+mat(1,1) = mat(0,0);
+mat(1,2) = mat(0,1);
+mat(2,1) = mat(1,0);
+mat(2,2) = mat(1,1);
+\endcode
+Thus, \c mat(2,2) is assigned the \e new value of \c mat(1,1) instead of the old value. The next section
+explains how to solve this problem by calling \link DenseBase::eval() eval()\endlink.
+
+Aliasing occurs more naturally when trying to shrink a matrix. For example, the expressions <tt>vec =
+vec.head(n)</tt> and <tt>mat = mat.block(i,j,r,c)</tt> exhibit aliasing.
+
+In general, aliasing cannot be detected at compile time: if \c mat in the first example were a bit bigger,
+then the blocks would not overlap, and there would be no aliasing problem. However, %Eigen does detect some
+instances of aliasing, albeit at run time.  The following example exhibiting aliasing was mentioned in \ref
+TutorialMatrixArithmetic :
+
+<table class="example">
+<tr><th>Example</th><th>Output</th></tr>
+<tr><td>
+\include tut_arithmetic_transpose_aliasing.cpp
+</td>
+<td>
+\verbinclude tut_arithmetic_transpose_aliasing.out
+</td></tr></table>
+
+Again, the output shows the aliasing issue. However, by default %Eigen uses a run-time assertion to detect this
+and exits with a message like
+
+\verbatim
+void Eigen::DenseBase<Derived>::checkTransposeAliasing(const OtherDerived&) const 
+[with OtherDerived = Eigen::Transpose<Eigen::Matrix<int, 2, 2, 0, 2, 2> >, Derived = Eigen::Matrix<int, 2, 2, 0, 2, 2>]: 
+Assertion `(!internal::check_transpose_aliasing_selector<Scalar,internal::blas_traits<Derived>::IsTransposed,OtherDerived>::run(internal::extract_data(derived()), other)) 
+&& "aliasing detected during transposition, use transposeInPlace() or evaluate the rhs into a temporary using .eval()"' failed.
+\endverbatim
+
+The user can turn %Eigen's run-time assertions like the one to detect this aliasing problem off by defining the
+EIGEN_NO_DEBUG macro, and the above program was compiled with this macro turned off in order to illustrate the
+aliasing problem. See \ref TopicAssertions for more information about %Eigen's run-time assertions.
+
+
+\section TopicAliasingSolution Resolving aliasing issues
+
+If you understand the cause of the aliasing issue, then it is obvious what must happen to solve it: %Eigen has
+to evaluate the right-hand side fully into a temporary matrix/array and then assign it to the left-hand
+side. The function \link DenseBase::eval() eval() \endlink does precisely that.
+
+For example, here is the corrected version of the first example above:
+
+<table class="example">
+<tr><th>Example</th><th>Output</th></tr>
+<tr><td>
+\include TopicAliasing_block_correct.cpp

+</td></tr></table>
+
+Now, \c mat(2,2) equals 5 after the assignment, as it should be.
+
+The same solution also works for the second example, with the transpose: simply replace the line 
+<tt>a = a.transpose();</tt> with <tt>a = a.transpose().eval();</tt>. However, in this common case there is a
+better solution. %Eigen provides the special-purpose function 
+\link DenseBase::transposeInPlace() transposeInPlace() \endlink which replaces a matrix by its transpose. 
+This is shown below:
+
+<table class="example">
+<tr><th>Example</th><th>Output</th></tr>
+<tr><td>
+\include tut_arithmetic_transpose_inplace.cpp
+</td>
+<td>
+\verbinclude tut_arithmetic_transpose_inplace.out
+</td></tr></table>
+
+If an xxxInPlace() function is available, then it is best to use it, because it indicates more clearly what you
+are doing. This may also allow %Eigen to optimize more aggressively. These are some of the xxxInPlace()
+functions provided: 
+
+<table class="manual">
+<tr><th>Original function</th><th>In-place function</th></tr>
+<tr> <td> MatrixBase::adjoint() </td> <td> MatrixBase::adjointInPlace() </td> </tr>
+<tr class="alt"> <td> DenseBase::reverse() </td> <td> DenseBase::reverseInPlace() </td> </tr>

+<tr> <td> TriangularView::solve() </td> <td> TriangularView::solveInPlace() </td> </tr>
+<tr class="alt"> <td> DenseBase::transpose() </td> <td> DenseBase::transposeInPlace() </td> </tr>
+</table>
+
+In the special case where a matrix or vector is shrunk using an expression like <tt>vec = vec.head(n)</tt>,
+you can use \link PlainObjectBase::conservativeResize() conservativeResize() \endlink.
+
+
+\section TopicAliasingCwise Aliasing and component-wise operations
+
+As explained above, it may be dangerous if the same matrix or array occurs on both the left-hand side and the
+right-hand side of an assignment operator, and it is then often necessary to evaluate the right-hand side
+explicitly. However, applying component-wise operations (such as matrix addition, scalar multiplication and
+array multiplication) is safe. 
+
+The following example has only component-wise operations. Thus, there is no need for \link DenseBase::eval()
+eval() \endlink even though the same matrix appears on both sides of the assignments.
+
+<table class="example">
+<tr><th>Example</th><th>Output</th></tr>
+<tr><td>
+\include TopicAliasing_cwise.cpp
+</td>
+<td>
+\verbinclude TopicAliasing_cwise.out
+</td></tr></table>
+
+In general, an assignment is safe if the (i,j) entry of the expression on the right-hand side depends only on
+the (i,j) entry of the matrix or array on the left-hand side and not on any other entries. In that case it is
+not necessary to evaluate the right-hand side explicitly.
+
+
+\section TopicAliasingMatrixMult Aliasing and matrix multiplication
+
+Matrix multiplication is the only operation in %Eigen that assumes aliasing by default, <strong>under the
+condition that the destination matrix is not resized</strong>.
+Thus, if \c matA is a \b squared matrix, then the statement <tt>matA = matA * matA;</tt> is safe.
+All other operations in %Eigen assume that there are no aliasing problems,
+either because the result is assigned to a different matrix or because it is a component-wise operation.
+
+<table class="example">
+<tr><th>Example</th><th>Output</th></tr>
+<tr><td>
+\include TopicAliasing_mult1.cpp
+</td>
+<td>
+\verbinclude TopicAliasing_mult1.out
+</td></tr></table>
+
+However, this comes at a price. When executing the expression <tt>matA = matA * matA</tt>, %Eigen evaluates the
+product in a temporary matrix which is assigned to \c matA after the computation. This is fine. But %Eigen does
+the same when the product is assigned to a different matrix (e.g., <tt>matB = matA * matA</tt>). In that case,
+it is more efficient to evaluate the product directly into \c matB instead of evaluating it first into a
+temporary matrix and copying that matrix to \c matB.
+
+The user can indicate with the \link MatrixBase::noalias() noalias()\endlink function that there is no
+aliasing, as follows: <tt>matB.noalias() = matA * matA</tt>. This allows %Eigen to evaluate the matrix product
+<tt>matA * matA</tt> directly into \c matB.
+
+<table class="example">
+<tr><th>Example</th><th>Output</th></tr>
+<tr><td>
+\include TopicAliasing_mult2.cpp
+</td>
+<td>
+\verbinclude TopicAliasing_mult2.out
+</td></tr></table>
+
+Of course, you should not use \c noalias() when there is in fact aliasing taking place. If you do, then you
+may get wrong results:
+
+<table class="example">
+<tr><th>Example</th><th>Output</th></tr>
+<tr><td>
+\include TopicAliasing_mult3.cpp
+</td>
+<td>
+\verbinclude TopicAliasing_mult3.out
+</td></tr></table>
+
+Moreover, starting in Eigen 3.3, aliasing is \b not assumed if the destination matrix is resized and the product is not directly assigned to the destination.
+Therefore, the following example is also wrong:
+
+<table class="example">
+<tr><th>Example</th><th>Output</th></tr>
+<tr><td>
+\include TopicAliasing_mult4.cpp
+</td>
+<td>
+\verbinclude TopicAliasing_mult4.out
+</td></tr></table>
+
+As for any aliasing issue, you can resolve it by explicitly evaluating the expression prior to assignment:
+<table class="example">
+<tr><th>Example</th><th>Output</th></tr>
+<tr><td>
+\include TopicAliasing_mult5.cpp
+</td>
+<td>
+\verbinclude TopicAliasing_mult5.out
+</td></tr></table>
+
+\section TopicAliasingSummary Summary
+
+Aliasing occurs when the same matrix or array coefficients appear both on the left- and the right-hand side of
+an assignment operator.
+ - Aliasing is harmless with coefficient-wise computations; this includes scalar multiplication and matrix or
+   array addition.
+ - When you multiply two matrices, %Eigen assumes that aliasing occurs. If you know that there is no aliasing,
+   then you can use \link MatrixBase::noalias() noalias()\endlink.
+ - In all other situations, %Eigen assumes that there is no aliasing issue and thus gives the wrong result if
+   aliasing does in fact occur. To prevent this, you have to use \link DenseBase::eval() eval() \endlink or
+   one of the xxxInPlace() functions.

+
+\eigenAutoToc
+
+\section PlainAssert Assertions
+
+The macro eigen_assert is defined to be \c eigen_plain_assert by default. We use eigen_plain_assert instead of \c assert to work around a known bug for GCC <= 4.3. Basically, eigen_plain_assert \a is \c assert.
+
+\subsection RedefineAssert Redefining assertions
+
+Both eigen_assert and eigen_plain_assert are defined in Macros.h. Defining eigen_assert indirectly gives you a chance to change its behavior. You can redefine this macro if you want to do something else such as throwing an exception, and fall back to its default behavior with eigen_plain_assert. The code below tells Eigen to throw an std::runtime_error:
+
+\code
+#include <stdexcept>
+#undef eigen_assert
+#define eigen_assert(x) \
+  if (!(x)) { throw (std::runtime_error("Put your message here")); }
+\endcode
+
+\subsection DisableAssert Disabling assertions
+
+Assertions cost run time and can be turned off. You can suppress eigen_assert by defining \c EIGEN_NO_DEBUG \b before including Eigen headers. \c EIGEN_NO_DEBUG is undefined by default unless \c NDEBUG is defined.
+
+\section StaticAssert Static assertions
+
+Static assertions are not standardized until C++11. However, in the Eigen library, there are many conditions can and should be detectedat compile time. For instance, we use static assertions to prevent the code below from compiling.
+
+\code
+Matrix3d()  + Matrix4d();   // adding matrices of different sizes
+Matrix4cd() * Vector3cd();  // invalid product known at compile time
+\endcode
+
+Static assertions are defined in StaticAssert.h. If there is native static_assert, we use it. Otherwise, we have implemented an assertion macro that can show a limited range of messages.
+
+One can easily come up with static assertions without messages, such as:
+
+\code
+#define STATIC_ASSERT(x) \
+  switch(0) { case 0: case x:; }
+\endcode
+
+However, the example above obviously cannot tell why the assertion failed. Therefore, we define a \c struct in namespace Eigen::internal to handle available messages.
+
+\code
+template<bool condition>
+struct static_assertion {};
+
+template<>
+struct static_assertion<true>
+{
+  enum {
+    YOU_TRIED_CALLING_A_VECTOR_METHOD_ON_A_MATRIX,
+    YOU_MIXED_VECTORS_OF_DIFFERENT_SIZES,
+    // see StaticAssert.h for all enums.
+  };
+};
+\endcode
+
+And then, we define EIGEN_STATIC_ASSERT(CONDITION,MSG) to access Eigen::internal::static_assertion<bool(CONDITION)>::MSG. If the condition evaluates into \c false, your compiler displays a lot of messages explaining there is no MSG in static_assert<false>. Nevertheless, this is \a not in what we are interested. As you can see, all members of static_assert<true> are ALL_CAPS_AND_THEY_ARE_SHOUTING.
+
+\warning
+When using this macro, MSG should be a member of static_assertion<true>, or the static assertion \b always fails.
+Currently, it can only be used in function scope.
+
+\subsection DerivedStaticAssert Derived static assertions
+
+There are other macros derived from EIGEN_STATIC_ASSERT to enhance readability. Their names are self-explanatory.
+
+- \b EIGEN_STATIC_ASSERT_FIXED_SIZE(TYPE) - passes if \a TYPE is fixed size.
+- \b EIGEN_STATIC_ASSERT_DYNAMIC_SIZE(TYPE) - passes if \a TYPE is dynamic size.
+- \b EIGEN_STATIC_ASSERT_LVALUE(Derived) - failes if \a Derived is read-only.
+- \b EIGEN_STATIC_ASSERT_ARRAYXPR(Derived) - passes if \a Derived is an array expression.
+- <b>EIGEN_STATIC_ASSERT_SAME_XPR_KIND(Derived1, Derived2)</b> - failes if the two expressions are an array one and a matrix one.
+
+Because Eigen handles both fixed-size and dynamic-size expressions, some conditions cannot be clearly determined at compile time. We classify them into strict assertions and permissive assertions.
+
+\subsubsection StrictAssertions Strict assertions
+
+These assertions fail if the condition <b>may not</b> be met. For example, MatrixXd may not be a vector, so it fails EIGEN_STATIC_ASSERT_VECTOR_ONLY.
+
+- \b EIGEN_STATIC_ASSERT_VECTOR_ONLY(TYPE) - passes if \a TYPE must be a vector type.
+- <b>EIGEN_STATIC_ASSERT_VECTOR_SPECIFIC_SIZE(TYPE, SIZE)</b> - passes if \a TYPE must be a vector of the given size.
+- <b>EIGEN_STATIC_ASSERT_MATRIX_SPECIFIC_SIZE(TYPE, ROWS, COLS)</b> - passes if \a TYPE must be a matrix with given rows and columns.
+
+\subsubsection PermissiveAssertions Permissive assertions
+
+These assertions fail if the condition \b cannot be met. For example, MatrixXd and Matrix4d may have the same size, so they pass EIGEN_STATIC_ASSERT_SAME_MATRIX_SIZE.
+
+- \b EIGEN_STATIC_ASSERT_SAME_VECTOR_SIZE(TYPE0,TYPE1) - fails if the two vector expression types must have different sizes.
+- \b EIGEN_STATIC_ASSERT_SAME_MATRIX_SIZE(TYPE0,TYPE1) - fails if the two matrix expression types must have different sizes.
+- \b EIGEN_STATIC_ASSERT_SIZE_1x1(TYPE) - fails if \a TYPE cannot be an 1x1 expression.
+
+See StaticAssert.h for details such as what messages they throw.
+
+\subsection DisableStaticAssert Disabling static assertions
+
+If \c EIGEN_NO_STATIC_ASSERT is defined, static assertions turn into <tt>eigen_assert</tt>'s, working like:
+
+\code
+#define EIGEN_STATIC_ASSERT(CONDITION,MSG) eigen_assert((CONDITION) && #MSG);
+\endcode
+
+This saves compile time but consumes more run time. \c EIGEN_NO_STATIC_ASSERT is undefined by default.

+\page TopicCMakeGuide Using %Eigen in CMake Projects
+
+%Eigen provides native CMake support which allows the library to be easily
+used in CMake projects.
+
+\note %CMake 3.0 (or later) is required to enable this functionality.
+
+%Eigen exports a CMake target called `Eigen3::Eigen` which can be imported
+using the `find_package` CMake command and used by calling
+`target_link_libraries` as in the following example:
+\code{.cmake}
+cmake_minimum_required (VERSION 3.0)
+project (myproject)
+
+find_package (Eigen3 3.3 REQUIRED NO_MODULE)
+
+add_executable (example example.cpp)
+target_link_libraries (example Eigen3::Eigen)
+\endcode
+
+The above code snippet must be placed in a file called `CMakeLists.txt` alongside
+`example.cpp`. After running
+\code{.sh}
+$ cmake path-to-example-directory
+\endcode
+CMake will produce project files that generate an executable called `example`
+which requires at least version 3.3 of %Eigen. Here, `path-to-example-directory`
+is the path to the directory that contains both `CMakeLists.txt` and
+`example.cpp`.
+
+If you have multiple installed version of %Eigen, you can pick your favorite one by setting the \c Eigen3_DIR cmake's variable to the respective path containing the \c Eigen3*.cmake files. For instance:
+\code
+cmake path-to-example-directory -DEigen3_DIR=$HOME/mypackages/share/eigen3/cmake/
+\endcode
+
+If the `REQUIRED` option is omitted when locating %Eigen using
+`find_package`, one can check whether the package was found as follows:
+\code{.cmake}
+find_package (Eigen3 3.3 NO_MODULE)
+
+if (TARGET Eigen3::Eigen)
+  # Use the imported target
+endif (TARGET Eigen3::Eigen)

+/** \page TopicLazyEvaluation Lazy Evaluation and Aliasing
+
+Executive summary: Eigen has intelligent compile-time mechanisms to enable lazy evaluation and removing temporaries where appropriate.
+It will handle aliasing automatically in most cases, for example with matrix products. The automatic behavior can be overridden
+manually by using the MatrixBase::eval() and MatrixBase::noalias() methods.
+
+When you write a line of code involving a complex expression such as
+
+\code mat1 = mat2 + mat3 * (mat4 + mat5); \endcode
+
+Eigen determines automatically, for each sub-expression, whether to evaluate it into a temporary variable. Indeed, in certain cases it is better to evaluate immediately a sub-expression into a temporary variable, while in other cases it is better to avoid that.
+
+A traditional math library without expression templates always evaluates all sub-expressions into temporaries. So with this code,
+
+\code vec1 = vec2 + vec3; \endcode
+
+a traditional library would evaluate \c vec2 + vec3 into a temporary \c vec4 and then copy \c vec4  into \c vec1. This is of course inefficient: the arrays are traversed twice, so there are a lot of useless load/store operations.
+
+Expression-templates-based libraries can avoid evaluating sub-expressions into temporaries, which in many cases results in large speed improvements. This is called <i>lazy evaluation</i> as an expression is getting evaluated as late as possible, instead of immediately. However, most other expression-templates-based libraries <i>always</i> choose lazy evaluation. There are two problems with that: first, lazy evaluation is not always a good choice for performance; second, lazy evaluation can be very dangerous, for example with matrix products: doing <tt>matrix = matrix*matrix</tt> gives a wrong result if the matrix product is lazy-evaluated, because of the way matrix product works.
+
+For these reasons, Eigen has intelligent compile-time mechanisms to determine automatically when to use lazy evaluation, and when on the contrary it should evaluate immediately into a temporary variable.
+
+So in the basic example,
+
+\code matrix1 = matrix2 + matrix3; \endcode
+
+Eigen chooses lazy evaluation. Thus the arrays are traversed only once, producing optimized code. If you really want to force immediate evaluation, use \link MatrixBase::eval() eval()\endlink:
+
+\code matrix1 = (matrix2 + matrix3).eval(); \endcode
+
+Here is now a more involved example:
+
+\code matrix1 = -matrix2 + matrix3 + 5 * matrix4; \endcode
+
+Eigen chooses lazy evaluation at every stage in that example, which is clearly the correct choice. In fact, lazy evaluation is the "default choice" and Eigen will choose it except in a few circumstances.
+
+<b>The first circumstance</b> in which Eigen chooses immediate evaluation, is when it sees an assignment <tt>a = b;</tt> and the expression \c b has the evaluate-before-assigning \link flags flag\endlink. The most important example of such an expression is the \link Product matrix product expression\endlink. For example, when you do
+
+\code matrix = matrix * matrix; \endcode
+
+Eigen first evaluates <tt>matrix * matrix</tt> into a temporary matrix, and then copies it into the original \c matrix. This guarantees a correct result as we saw above that lazy evaluation gives wrong results with matrix products. It also doesn't cost much, as the cost of the matrix product itself is much higher.
+
+What if you know that the result does no alias the operand of the product and want to force lazy evaluation? Then use \link MatrixBase::noalias() .noalias()\endlink instead. Here is an example:
+
+\code matrix1.noalias() = matrix2 * matrix2; \endcode
+
+Here, since we know that matrix2 is not the same matrix as matrix1, we know that lazy evaluation is not dangerous, so we may force lazy evaluation. Concretely, the effect of noalias() here is to bypass the evaluate-before-assigning \link flags flag\endlink.
+
+<b>The second circumstance</b> in which Eigen chooses immediate evaluation, is when it sees a nested expression such as <tt>a + b</tt> where \c b is already an expression having the evaluate-before-nesting \link flags flag\endlink. Again, the most important example of such an expression is the \link Product matrix product expression\endlink. For example, when you do
+
+\code matrix1 = matrix2 + matrix3 * matrix4; \endcode
+
+the product <tt>matrix3 * matrix4</tt> gets evaluated immediately into a temporary matrix. Indeed, experiments showed that it is often beneficial for performance to evaluate immediately matrix products when they are nested into bigger expressions.
+
+<b>The third circumstance</b> in which Eigen chooses immediate evaluation, is when its cost model shows that the total cost of an operation is reduced if a sub-expression gets evaluated into a temporary. Indeed, in certain cases, an intermediate result is sufficiently costly to compute and is reused sufficiently many times, that is worth "caching". Here is an example:
+
+\code matrix1 = matrix2 * (matrix3 + matrix4); \endcode
+
+Here, provided the matrices have at least 2 rows and 2 columns, each coefficienct of the expression <tt>matrix3 + matrix4</tt> is going to be used several times in the matrix product. Instead of computing the sum everytime, it is much better to compute it once and store it in a temporary variable. Eigen understands this and evaluates <tt>matrix3 + matrix4</tt> into a temporary variable before evaluating the product.

+\section TopicMultiThreading_MakingEigenMT Make Eigen run in parallel
+
+Some Eigen's algorithms can exploit the multiple cores present in your hardware. To this end, it is enough to enable OpenMP on your compiler, for instance:
+ * GCC: \c -fopenmp
+ * ICC: \c -openmp
+ * MSVC: check the respective option in the build properties.
+You can control the number of thread that will be used using either the OpenMP API or Eigen's API using the following priority:
+\code
+ OMP_NUM_THREADS=n ./my_program
+ omp_set_num_threads(n);
+ Eigen::setNbThreads(n);
+\endcode
+Unless setNbThreads has been called, Eigen uses the number of threads specified by OpenMP. You can restore this behavior by calling \code setNbThreads(0); \endcode
+You can query the number of threads that will be used with:
+\code
+n = Eigen::nbThreads( );
+\endcode
+You can disable Eigen's multi threading at compile time by defining the EIGEN_DONT_PARALLELIZE preprocessor token.
+
+Currently, the following algorithms can make use of multi-threading:
+ - general dense matrix - matrix products
+ - PartialPivLU
+ - row-major-sparse * dense vector/matrix products
+ - ConjugateGradient with \c Lower|Upper as the \c UpLo template parameter.
+ - BiCGSTAB with a row-major sparse matrix format.
+ - LeastSquaresConjugateGradient
+
+\section TopicMultiThreading_UsingEigenWithMT Using Eigen in a multi-threaded application
+
+In the case your own application is multithreaded, and multiple threads make calls to Eigen, then you have to initialize Eigen by calling the following routine \b before creating the threads:
+\code
+#include <Eigen/Core>
+
+int main(int argc, char** argv)
+{
+  Eigen::initParallel();
+  
+  ...
+}
+\endcode
+
+\note With Eigen 3.3, and a fully C++11 compliant compiler (i.e., <a href="http://en.cppreference.com/w/cpp/language/storage_duration#Static_local_variables">thread-safe static local variable initialization</a>), then calling \c initParallel() is optional.
+
+\warning note that all functions generating random matrices are \b not re-entrant nor thread-safe. Those include DenseBase::Random(), and DenseBase::setRandom() despite a call to Eigen::initParallel(). This is because these functions are based on std::rand which is not re-entrant. For thread-safe random generator, we recommend the use of boost::random or c++11 random feature.
+
+In the case your application is parallelized with OpenMP, you might want to disable Eigen's own parallization as detailed in the previous section.

+
+This page discusses several advanced methods for initializing matrices. It gives more details on the
+comma-initializer, which was introduced before. It also explains how to get special matrices such as the
+identity matrix and the zero matrix.
+
+\eigenAutoToc
+
+\section TutorialAdvancedInitializationCommaInitializer The comma initializer
+
+Eigen offers a comma initializer syntax which allows the user to easily set all the coefficients of a matrix,
+vector or array. Simply list the coefficients, starting at the top-left corner and moving from left to right
+and from the top to the bottom. The size of the object needs to be specified beforehand. If you list too few
+or too many coefficients, Eigen will complain.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_commainit_01.cpp
+</td>
+<td>
+\verbinclude Tutorial_commainit_01.out
+</td></tr></table>
+
+Moreover, the elements of the initialization list may themselves be vectors or matrices. A common use is
+to join vectors or matrices together. For example, here is how to join two row vectors together. Remember
+that you have to set the size before you can use the comma initializer.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_AdvancedInitialization_Join.cpp
+</td>
+<td>
+\verbinclude Tutorial_AdvancedInitialization_Join.out
+</td></tr></table>
+
+We can use the same technique to initialize matrices with a block structure.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_AdvancedInitialization_Block.cpp
+</td>
+<td>
+\verbinclude Tutorial_AdvancedInitialization_Block.out
+</td></tr></table>
+
+The comma initializer can also be used to fill block expressions such as <tt>m.row(i)</tt>. Here is a more
+complicated way to get the same result as in the first example above:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_commainit_01b.cpp
+</td>
+<td>
+\verbinclude Tutorial_commainit_01b.out
+</td></tr></table>
+
+
+\section TutorialAdvancedInitializationSpecialMatrices Special matrices and arrays
+
+The Matrix and Array classes have static methods like \link DenseBase::Zero() Zero()\endlink, which can be
+used to initialize all coefficients to zero. There are three variants. The first variant takes no arguments
+and can only be used for fixed-size objects. If you want to initialize a dynamic-size object to zero, you need
+to specify the size. Thus, the second variant requires one argument and can be used for one-dimensional
+dynamic-size objects, while the third variant requires two arguments and can be used for two-dimensional
+objects. All three variants are illustrated in the following example:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_AdvancedInitialization_Zero.cpp
+</td>
+<td>
+\verbinclude Tutorial_AdvancedInitialization_Zero.out
+</td></tr></table>
+
+Similarly, the static method \link DenseBase::Constant() Constant\endlink(value) sets all coefficients to \c value.
+If the size of the object needs to be specified, the additional arguments go before the \c value
+argument, as in <tt>MatrixXd::Constant(rows, cols, value)</tt>. The method \link DenseBase::Random() Random()
+\endlink fills the matrix or array with random coefficients. The identity matrix can be obtained by calling
+\link MatrixBase::Identity() Identity()\endlink; this method is only available for Matrix, not for Array,
+because "identity matrix" is a linear algebra concept.  The method
+\link DenseBase::LinSpaced LinSpaced\endlink(size, low, high) is only available for vectors and
+one-dimensional arrays; it yields a vector of the specified size whose coefficients are equally spaced between
+\c low and \c high. The method \c LinSpaced() is illustrated in the following example, which prints a table
+with angles in degrees, the corresponding angle in radians, and their sine and cosine.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_AdvancedInitialization_LinSpaced.cpp
+</td>
+<td>
+\verbinclude Tutorial_AdvancedInitialization_LinSpaced.out
+</td></tr></table>
+
+This example shows that objects like the ones returned by LinSpaced() can be assigned to variables (and
+expressions). Eigen defines utility functions like \link DenseBase::setZero() setZero()\endlink, 
+\link MatrixBase::setIdentity() \endlink and \link DenseBase::setLinSpaced() \endlink to do this
+conveniently. The following example contrasts three ways to construct the matrix
+\f$ J = \bigl[ \begin{smallmatrix} O & I \\ I & O \end{smallmatrix} \bigr] \f$: using static methods and
+assignment, using static methods and the comma-initializer, or using the setXxx() methods.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_AdvancedInitialization_ThreeWays.cpp
+</td>
+<td>
+\verbinclude Tutorial_AdvancedInitialization_ThreeWays.out
+</td></tr></table>
+
+A summary of all pre-defined matrix, vector and array objects can be found in the \ref QuickRefPage.
+
+
+\section TutorialAdvancedInitializationTemporaryObjects Usage as temporary objects
+
+As shown above, static methods as Zero() and Constant() can be used to initialize variables at the time of
+declaration or at the right-hand side of an assignment operator. You can think of these methods as returning a
+matrix or array; in fact, they return so-called \ref TopicEigenExpressionTemplates "expression objects" which
+evaluate to a matrix or array when needed, so that this syntax does not incur any overhead.
+
+These expressions can also be used as a temporary object. The second example in
+the \ref GettingStarted guide, which we reproduce here, already illustrates this.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include QuickStart_example2_dynamic.cpp
+</td>
+<td>
+\verbinclude QuickStart_example2_dynamic.out
+</td></tr></table>
+
+The expression <tt>m + MatrixXf::Constant(3,3,1.2)</tt> constructs the 3-by-3 matrix expression with all its coefficients
+equal to 1.2 plus the corresponding coefficient of \a m.
+
+The comma-initializer, too, can also be used to construct temporary objects. The following example constructs a random
+matrix of size 2-by-3, and then multiplies this matrix on the left with 
+\f$ \bigl[ \begin{smallmatrix} 0 & 1 \\ 1 & 0 \end{smallmatrix} \bigr] \f$.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_AdvancedInitialization_CommaTemporary.cpp
+</td>
+<td>
+\verbinclude Tutorial_AdvancedInitialization_CommaTemporary.out
+</td></tr></table>
+
+The \link CommaInitializer::finished() finished() \endlink method is necessary here to get the actual matrix
+object once the comma initialization of our temporary submatrix is done.

+
+/** \eigenManualPage TutorialArrayClass The Array class and coefficient-wise operations
+
+This page aims to provide an overview and explanations on how to use
+Eigen's Array class.
+
+\eigenAutoToc
+  
+\section TutorialArrayClassIntro What is the Array class?
+
+The Array class provides general-purpose arrays, as opposed to the Matrix class which
+is intended for linear algebra. Furthermore, the Array class provides an easy way to
+perform coefficient-wise operations, which might not have a linear algebraic meaning,
+such as adding a constant to every coefficient in the array or multiplying two arrays coefficient-wise.
+
+
+\section TutorialArrayClassTypes Array types
+Array is a class template taking the same template parameters as Matrix.
+As with Matrix, the first three template parameters are mandatory:
+\code
+Array<typename Scalar, int RowsAtCompileTime, int ColsAtCompileTime>
+\endcode
+The last three template parameters are optional. Since this is exactly the same as for Matrix,
+we won't explain it again here and just refer to \ref TutorialMatrixClass.
+
+Eigen also provides typedefs for some common cases, in a way that is similar to the Matrix typedefs
+but with some slight differences, as the word "array" is used for both 1-dimensional and 2-dimensional arrays.
+We adopt the convention that typedefs of the form ArrayNt stand for 1-dimensional arrays, where N and t are
+the size and the scalar type, as in the Matrix typedefs explained on \ref TutorialMatrixClass "this page". For 2-dimensional arrays, we
+use typedefs of the form ArrayNNt. Some examples are shown in the following table:
+
+<table class="manual">
+  <tr>
+    <th>Type </th>
+    <th>Typedef </th>
+  </tr>
+  <tr>
+    <td> \code Array<float,Dynamic,1> \endcode </td>
+    <td> \code ArrayXf \endcode </td>
+  </tr>
+  <tr>
+    <td> \code Array<float,3,1> \endcode </td>
+    <td> \code Array3f \endcode </td>
+  </tr>
+  <tr>
+    <td> \code Array<double,Dynamic,Dynamic> \endcode </td>
+    <td> \code ArrayXXd \endcode </td>
+  </tr>
+  <tr>
+    <td> \code Array<double,3,3> \endcode </td>
+    <td> \code Array33d \endcode </td>
+  </tr>
+</table>
+
+
+\section TutorialArrayClassAccess Accessing values inside an Array
+
+The parenthesis operator is overloaded to provide write and read access to the coefficients of an array, just as with matrices.
+Furthermore, the \c << operator can be used to initialize arrays (via the comma initializer) or to print them.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ArrayClass_accessors.cpp
+</td>
+<td>
+\verbinclude Tutorial_ArrayClass_accessors.out
+</td></tr></table>
+
+For more information about the comma initializer, see \ref TutorialAdvancedInitialization.
+
+
+\section TutorialArrayClassAddSub Addition and subtraction
+
+Adding and subtracting two arrays is the same as for matrices.
+The operation is valid if both arrays have the same size, and the addition or subtraction is done coefficient-wise.
+
+Arrays also support expressions of the form <tt>array + scalar</tt> which add a scalar to each coefficient in the array.
+This provides a functionality that is not directly available for Matrix objects.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ArrayClass_addition.cpp
+</td>
+<td>
+\verbinclude Tutorial_ArrayClass_addition.out
+</td></tr></table>
+
+
+\section TutorialArrayClassMult Array multiplication
+
+First of all, of course you can multiply an array by a scalar, this works in the same way as matrices. Where arrays
+are fundamentally different from matrices, is when you multiply two together. Matrices interpret
+multiplication as matrix product and arrays interpret multiplication as coefficient-wise product. Thus, two 
+arrays can be multiplied if and only if they have the same dimensions.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ArrayClass_mult.cpp
+</td>
+<td>
+\verbinclude Tutorial_ArrayClass_mult.out
+</td></tr></table>
+
+
+\section TutorialArrayClassCwiseOther Other coefficient-wise operations
+
+The Array class defines other coefficient-wise operations besides the addition, subtraction and multiplication
+operators described above. For example, the \link ArrayBase::abs() .abs() \endlink method takes the absolute
+value of each coefficient, while \link ArrayBase::sqrt() .sqrt() \endlink computes the square root of the
+coefficients. If you have two arrays of the same size, you can call \link ArrayBase::min(const Eigen::ArrayBase<OtherDerived>&) const .min(.) \endlink to
+construct the array whose coefficients are the minimum of the corresponding coefficients of the two given
+arrays. These operations are illustrated in the following example.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ArrayClass_cwise_other.cpp
+</td>
+<td>
+\verbinclude Tutorial_ArrayClass_cwise_other.out
+</td></tr></table>
+
+More coefficient-wise operations can be found in the \ref QuickRefPage.
+
+
+\section TutorialArrayClassConvert Converting between array and matrix expressions
+
+When should you use objects of the Matrix class and when should you use objects of the Array class? You cannot
+apply Matrix operations on arrays, or Array operations on matrices. Thus, if you need to do linear algebraic
+operations such as matrix multiplication, then you should use matrices; if you need to do coefficient-wise
+operations, then you should use arrays. However, sometimes it is not that simple, but you need to use both
+Matrix and Array operations. In that case, you need to convert a matrix to an array or reversely. This gives
+access to all operations regardless of the choice of declaring objects as arrays or as matrices.
+
+\link MatrixBase Matrix expressions \endlink have an \link MatrixBase::array() .array() \endlink method that
+'converts' them into \link ArrayBase array expressions\endlink, so that coefficient-wise operations
+can be applied easily. Conversely, \link ArrayBase array expressions \endlink
+have a \link ArrayBase::matrix() .matrix() \endlink method. As with all Eigen expression abstractions,
+this doesn't have any runtime cost (provided that you let your compiler optimize).
+Both \link MatrixBase::array() .array() \endlink and \link ArrayBase::matrix() .matrix() \endlink 
+can be used as rvalues and as lvalues.
+
+Mixing matrices and arrays in an expression is forbidden with Eigen. For instance, you cannot add a matrix and
+array directly; the operands of a \c + operator should either both be matrices or both be arrays. However,
+it is easy to convert from one to the other with \link MatrixBase::array() .array() \endlink and 
+\link ArrayBase::matrix() .matrix()\endlink. The exception to this rule is the assignment operator: it is
+allowed to assign a matrix expression to an array variable, or to assign an array expression to a matrix
+variable.
+
+The following example shows how to use array operations on a Matrix object by employing the 
+\link MatrixBase::array() .array() \endlink method. For example, the statement 
+<tt>result = m.array() * n.array()</tt> takes two matrices \c m and \c n, converts them both to an array, uses
+* to multiply them coefficient-wise and assigns the result to the matrix variable \c result (this is legal
+because Eigen allows assigning array expressions to matrix variables). 
+
+As a matter of fact, this usage case is so common that Eigen provides a \link MatrixBase::cwiseProduct const
+.cwiseProduct(.) \endlink method for matrices to compute the coefficient-wise product. This is also shown in
+the example program.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ArrayClass_interop_matrix.cpp
+</td>
+<td>
+\verbinclude Tutorial_ArrayClass_interop_matrix.out
+</td></tr></table>
+
+Similarly, if \c array1 and \c array2 are arrays, then the expression <tt>array1.matrix() * array2.matrix()</tt>
+computes their matrix product.
+
+Here is a more advanced example. The expression <tt>(m.array() + 4).matrix() * m</tt> adds 4 to every
+coefficient in the matrix \c m and then computes the matrix product of the result with \c m. Similarly, the
+expression <tt>(m.array() * n.array()).matrix() * m</tt> computes the coefficient-wise product of the matrices
+\c m and \c n and then the matrix product of the result with \c m.

+/** \eigenManualPage TutorialBlockOperations Block operations
+
+This page explains the essentials of block operations.
+A block is a rectangular part of a matrix or array. Blocks expressions can be used both
+as rvalues and as lvalues. As usual with Eigen expressions, this abstraction has zero runtime cost
+provided that you let your compiler optimize.
+
+\eigenAutoToc
+
+\section TutorialBlockOperationsUsing Using block operations
+
+The most general block operation in Eigen is called \link DenseBase::block() .block() \endlink.
+There are two versions, whose syntax is as follows:
+
+<table class="manual">
+<tr><th>\b %Block \b operation</td>
+<th>Version constructing a \n dynamic-size block expression</th>
+<th>Version constructing a \n fixed-size block expression</th></tr>
+<tr><td>%Block of size <tt>(p,q)</tt>, starting at <tt>(i,j)</tt></td>
+    <td>\code
+matrix.block(i,j,p,q);\endcode </td>
+    <td>\code 
+matrix.block<p,q>(i,j);\endcode </td>
+</tr>
+</table>
+
+As always in Eigen, indices start at 0.
+
+Both versions can be used on fixed-size and dynamic-size matrices and arrays.
+These two expressions are semantically equivalent.
+The only difference is that the fixed-size version will typically give you faster code if the block size is small,
+but requires this size to be known at compile time.
+
+The following program uses the dynamic-size and fixed-size versions to print the values of several blocks inside a
+matrix.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_BlockOperations_print_block.cpp
+</td>
+<td>
+\verbinclude Tutorial_BlockOperations_print_block.out
+</td></tr></table>
+
+In the above example the \link DenseBase::block() .block() \endlink function was employed as a \em rvalue, i.e.
+it was only read from. However, blocks can also be used as \em lvalues, meaning that you can assign to a block.
+
+This is illustrated in the following example. This example also demonstrates blocks in arrays, which works exactly like the above-demonstrated blocks in matrices.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_BlockOperations_block_assignment.cpp
+</td>
+<td>
+\verbinclude Tutorial_BlockOperations_block_assignment.out
+</td></tr></table>
+
+While the \link DenseBase::block() .block() \endlink method can be used for any block operation, there are
+other methods for special cases, providing more specialized API and/or better performance. On the topic of performance, all what
+matters is that you give Eigen as much information as possible at compile time. For example, if your block is a single whole column in a matrix,
+using the specialized \link DenseBase::col() .col() \endlink function described below lets Eigen know that, which can give it optimization opportunities.
+
+The rest of this page describes these specialized methods.
+
+\section TutorialBlockOperationsSyntaxColumnRows Columns and rows
+
+Individual columns and rows are special cases of blocks. Eigen provides methods to easily address them:
+\link DenseBase::col() .col() \endlink and \link DenseBase::row() .row()\endlink.
+
+<table class="manual">
+<tr><th>%Block operation</th>
+<th>Method</th>
+<tr><td>i<sup>th</sup> row
+                    \link DenseBase::row() * \endlink</td>
+    <td>\code
+matrix.row(i);\endcode </td>
+</tr>
+<tr><td>j<sup>th</sup> column
+                    \link DenseBase::col() * \endlink</td>
+    <td>\code
+matrix.col(j);\endcode </td>
+</tr>
+</table>
+
+The argument for \p col() and \p row() is the index of the column or row to be accessed. As always in Eigen, indices start at 0.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_BlockOperations_colrow.cpp
+</td>
+<td>
+\verbinclude Tutorial_BlockOperations_colrow.out
+</td></tr></table>
+
+That example also demonstrates that block expressions (here columns) can be used in arithmetic like any other expression.
+
+
+\section TutorialBlockOperationsSyntaxCorners Corner-related operations
+
+Eigen also provides special methods for blocks that are flushed against one of the corners or sides of a
+matrix or array. For instance, \link DenseBase::topLeftCorner() .topLeftCorner() \endlink can be used to refer
+to a block in the top-left corner of a matrix.
+
+The different possibilities are summarized in the following table:
+
+<table class="manual">
+<tr><th>%Block \b operation</td>
+<th>Version constructing a \n dynamic-size block expression</th>
+<th>Version constructing a \n fixed-size block expression</th></tr>
+<tr><td>Top-left p by q block \link DenseBase::topLeftCorner() * \endlink</td>
+    <td>\code
+matrix.topLeftCorner(p,q);\endcode </td>
+    <td>\code 
+matrix.topLeftCorner<p,q>();\endcode </td>
+</tr>
+<tr><td>Bottom-left p by q block
+              \link DenseBase::bottomLeftCorner() * \endlink</td>
+    <td>\code
+matrix.bottomLeftCorner(p,q);\endcode </td>
+    <td>\code 
+matrix.bottomLeftCorner<p,q>();\endcode </td>
+</tr>
+<tr><td>Top-right p by q block
+              \link DenseBase::topRightCorner() * \endlink</td>
+    <td>\code
+matrix.topRightCorner(p,q);\endcode </td>
+    <td>\code 
+matrix.topRightCorner<p,q>();\endcode </td>
+</tr>
+<tr><td>Bottom-right p by q block
+               \link DenseBase::bottomRightCorner() * \endlink</td>
+    <td>\code
+matrix.bottomRightCorner(p,q);\endcode </td>
+    <td>\code 
+matrix.bottomRightCorner<p,q>();\endcode </td>
+</tr>
+<tr><td>%Block containing the first q rows
+                   \link DenseBase::topRows() * \endlink</td>
+    <td>\code
+matrix.topRows(q);\endcode </td>
+    <td>\code 
+matrix.topRows<q>();\endcode </td>
+</tr>
+<tr><td>%Block containing the last q rows
+                    \link DenseBase::bottomRows() * \endlink</td>
+    <td>\code
+matrix.bottomRows(q);\endcode </td>
+    <td>\code 
+matrix.bottomRows<q>();\endcode </td>
+</tr>
+<tr><td>%Block containing the first p columns
+                    \link DenseBase::leftCols() * \endlink</td>
+    <td>\code
+matrix.leftCols(p);\endcode </td>
+    <td>\code 
+matrix.leftCols<p>();\endcode </td>
+</tr>
+<tr><td>%Block containing the last q columns
+                    \link DenseBase::rightCols() * \endlink</td>
+    <td>\code
+matrix.rightCols(q);\endcode </td>
+    <td>\code 
+matrix.rightCols<q>();\endcode </td>
+</tr>
+</table>
+
+Here is a simple example illustrating the use of the operations presented above:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_BlockOperations_corner.cpp
+</td>
+<td>
+\verbinclude Tutorial_BlockOperations_corner.out
+</td></tr></table>
+
+
+\section TutorialBlockOperationsSyntaxVectors Block operations for vectors
+
+Eigen also provides a set of block operations designed specifically for the special case of vectors and one-dimensional arrays:
+
+<table class="manual">
+<tr><th> %Block operation</th>
+<th>Version constructing a \n dynamic-size block expression</th>
+<th>Version constructing a \n fixed-size block expression</th></tr>
+<tr><td>%Block containing the first \p n elements 
+                    \link DenseBase::head() * \endlink</td>
+    <td>\code
+vector.head(n);\endcode </td>
+    <td>\code 
+vector.head<n>();\endcode </td>
+</tr>
+<tr><td>%Block containing the last \p n elements
+                    \link DenseBase::tail() * \endlink</td>
+    <td>\code
+vector.tail(n);\endcode </td>
+    <td>\code 
+vector.tail<n>();\endcode </td>
+</tr>
+<tr><td>%Block containing \p n elements, starting at position \p i
+                    \link DenseBase::segment() * \endlink</td>
+    <td>\code
+vector.segment(i,n);\endcode </td>
+    <td>\code 
+vector.segment<n>(i);\endcode </td>
+</tr>
+</table>
+

+/** \eigenManualPage TutorialGeometry Space transformations
+
+In this page, we will introduce the many possibilities offered by the \ref Geometry_Module "geometry module" to deal with 2D and 3D rotations and projective or affine transformations.
+
+\eigenAutoToc
+
+Eigen's Geometry module provides two different kinds of geometric transformations:
+  - Abstract transformations, such as rotations (represented by \ref AngleAxis "angle and axis" or by a \ref Quaternion "quaternion"), \ref Translation "translations", \ref Scaling "scalings". These transformations are NOT represented as matrices, but you can nevertheless mix them with matrices and vectors in expressions, and convert them to matrices if you wish.
+  - Projective or affine transformation matrices: see the Transform class. These are really matrices.
+
+\note If you are working with OpenGL 4x4 matrices then Affine3f and Affine3d are what you want. Since Eigen defaults to column-major storage, you can directly use the Transform::data() method to pass your transformation matrix to OpenGL.
+
+You can construct a Transform from an abstract transformation, like this:
+\code
+  Transform t(AngleAxis(angle,axis));
+\endcode
+or like this:
+\code
+  Transform t;
+  t = AngleAxis(angle,axis);
+\endcode
+But note that unfortunately, because of how C++ works, you can \b not do this:
+\code
+  Transform t = AngleAxis(angle,axis);
+\endcode
+<span class="note">\b Explanation: In the C++ language, this would require Transform to have a non-explicit conversion constructor from AngleAxis, but we really don't want to allow implicit casting here.
+</span>
+
+\section TutorialGeoElementaryTransformations Transformation types

+Matrix<float,3> t = AngleAxisf(a,axis) * Scaling(s);\endcode</td></tr>
+</table>
+
+<strong>Notes on rotations</strong>\n To transform more than a single vector the preferred
+representations are rotation matrices, while for other usages Quaternion is the
+representation of choice as they are compact, fast and stable. Finally Rotation2D and
+AngleAxis are mainly convenient types to create other rotation objects.
+
+<strong>Notes on Translation and Scaling</strong>\n Like AngleAxis, these classes were
+designed to simplify the creation/initialization of linear (Matrix) and affine (Transform)
+transformations. Nevertheless, unlike AngleAxis which is inefficient to use, these classes
+might still be interesting to write generic and efficient algorithms taking as input any
+kind of transformations.
+
+Any of the above transformation types can be converted to any other types of the same nature,
+or to a more generic type. Here are some additional examples:
+<table class="manual">
+<tr><td>\code
+Rotation2Df r;  r  = Matrix2f(..);       // assumes a pure rotation matrix
+AngleAxisf aa;  aa = Quaternionf(..);
+AngleAxisf aa;  aa = Matrix3f(..);       // assumes a pure rotation matrix
+Matrix2f m;     m  = Rotation2Df(..);
+Matrix3f m;     m  = Quaternionf(..);       Matrix3f m;   m = Scaling(..);
+Affine3f m;     m  = AngleAxis3f(..);       Affine3f m;   m = Scaling(..);
+Affine3f m;     m  = Translation3f(..);     Affine3f m;   m = Matrix3f(..);
+\endcode</td></tr>
+</table>
+
+
+<a href="#" class="top">top</a>\section TutorialGeoCommontransformationAPI Common API across transformation types

+To some extent, Eigen's \ref Geometry_Module "geometry module" allows you to write
+generic algorithms working on any kind of transformation representations:

+Concatenation of two transformations</td><td>\code
+gen1 * gen2;\endcode</td></tr>

+Generic affine transformations are represented by the Transform class which internaly
+is a (Dim+1)^2 matrix. In Eigen we have chosen to not distinghish between points and
+vectors such that all points are actually represented by displacement vectors from the
+origin ( \f$ \mathbf{p} \equiv \mathbf{p}-0 \f$ ). With that in mind, real points and
+vector distinguish when the transformation is applied.

+\section TutorialLinAlgBasicSolve Basic linear solving
+
+\b The \b problem: You have a system of equations, that you have written as a single matrix equation
+    \f[ Ax \: = \: b \f]
+Where \a A and \a b are matrices (\a b could be a vector, as a special case). You want to find a solution \a x.
+
+\b The \b solution: You can choose between various decompositions, depending on what your matrix \a A looks like,
+and depending on whether you favor speed or accuracy. However, let's start with an example that works in all cases,
+and is a good compromise:
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+  <td>\include TutorialLinAlgExSolveColPivHouseholderQR.cpp </td>
+  <td>\verbinclude TutorialLinAlgExSolveColPivHouseholderQR.out </td>
+</tr>
+</table>
+
+In this example, the colPivHouseholderQr() method returns an object of class ColPivHouseholderQR. Since here the
+matrix is of type Matrix3f, this line could have been replaced by:
+\code
+ColPivHouseholderQR<Matrix3f> dec(A);
+Vector3f x = dec.solve(b);
+\endcode
+
+Here, ColPivHouseholderQR is a QR decomposition with column pivoting. It's a good compromise for this tutorial, as it
+works for all matrices while being quite fast. Here is a table of some other decompositions that you can choose from,
+depending on your matrix and the trade-off you want to make:

+To get an overview of the true relative speed of the different decompositions, check this \link DenseDecompositionBenchmark benchmark \endlink.
+
+All of these decompositions offer a solve() method that works as in the above example.
+
+For example, if your matrix is positive definite, the above table says that a very good
+choice is then the LLT or LDLT decomposition. Here's an example, also demonstrating that using a general
+matrix (not a vector) as right hand side is possible.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+  <td>\include TutorialLinAlgExSolveLDLT.cpp </td>
+  <td>\verbinclude TutorialLinAlgExSolveLDLT.out </td>

+
+For a \ref TopicLinearAlgebraDecompositions "much more complete table" comparing all decompositions supported by Eigen (notice that Eigen
+supports many other decompositions), see our special page on
+\ref TopicLinearAlgebraDecompositions "this topic".
+
+\section TutorialLinAlgSolutionExists Checking if a solution really exists
+
+Only you know what error margin you want to allow for a solution to be considered valid.
+So Eigen lets you do this computation for yourself, if you want to, as in this example:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+  <td>\include TutorialLinAlgExComputeSolveError.cpp </td>
+  <td>\verbinclude TutorialLinAlgExComputeSolveError.out </td>
+</tr>
+</table>
+
+\section TutorialLinAlgEigensolving Computing eigenvalues and eigenvectors
+
+You need an eigendecomposition here, see available such decompositions on \ref TopicLinearAlgebraDecompositions "this page".
+Make sure to check if your matrix is self-adjoint, as is often the case in these problems. Here's an example using
+SelfAdjointEigenSolver, it could easily be adapted to general matrices using EigenSolver or ComplexEigenSolver.
+
+The computation of eigenvalues and eigenvectors does not necessarily converge, but such failure to converge is
+very rare. The call to info() is to check for this possibility.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+  <td>\include TutorialLinAlgSelfAdjointEigenSolver.cpp </td>
+  <td>\verbinclude TutorialLinAlgSelfAdjointEigenSolver.out </td>
+</tr>
+</table>
+
+\section TutorialLinAlgInverse Computing inverse and determinant
+
+First of all, make sure that you really want this. While inverse and determinant are fundamental mathematical concepts,
+in \em numerical linear algebra they are not as popular as in pure mathematics. Inverse computations are often
+advantageously replaced by solve() operations, and the determinant is often \em not a good way of checking if a matrix
+is invertible.
+
+However, for \em very \em small matrices, the above is not true, and inverse and determinant can be very useful.
+
+While certain decompositions, such as PartialPivLU and FullPivLU, offer inverse() and determinant() methods, you can also
+call inverse() and determinant() directly on a matrix. If your matrix is of a very small fixed size (at most 4x4) this
+allows Eigen to avoid performing a LU decomposition, and instead use formulas that are more efficient on such small matrices.
+
+Here is an example:
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+  <td>\include TutorialLinAlgInverseDeterminant.cpp </td>
+  <td>\verbinclude TutorialLinAlgInverseDeterminant.out </td>
+</tr>
+</table>
+
+\section TutorialLinAlgLeastsquares Least squares solving
+
+The most accurate method to do least squares solving is with a SVD decomposition.
+Eigen provides two implementations.
+The recommended one is the BDCSVD class, which scale well for large problems
+and automatically fall-back to the JacobiSVD class for smaller problems.
+For both classes, their solve() method is doing least-squares solving.
+
+Here is an example:
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+  <td>\include TutorialLinAlgSVDSolve.cpp </td>
+  <td>\verbinclude TutorialLinAlgSVDSolve.out </td>
+</tr>
+</table>
+
+Another methods, potentially faster but less reliable, are to use a Cholesky decomposition of the
+normal matrix or a QR decomposition. Our page on \link LeastSquares least squares solving \endlink
+has more details.
+
+
+\section TutorialLinAlgSeparateComputation Separating the computation from the construction
+
+In the above examples, the decomposition was computed at the same time that the decomposition object was constructed.
+There are however situations where you might want to separate these two things, for example if you don't know,
+at the time of the construction, the matrix that you will want to decompose; or if you want to reuse an existing
+decomposition object.
+
+What makes this possible is that:
+\li all decompositions have a default constructor,
+\li all decompositions have a compute(matrix) method that does the computation, and that may be called again
+    on an already-computed decomposition, reinitializing it.
+
+For example:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+  <td>\include TutorialLinAlgComputeTwice.cpp </td>
+  <td>\verbinclude TutorialLinAlgComputeTwice.out </td>
+</tr>
+</table>
+
+Finally, you can tell the decomposition constructor to preallocate storage for decomposing matrices of a given size,
+so that when you subsequently decompose such matrices, no dynamic memory allocation is performed (of course, if you
+are using fixed-size matrices, no dynamic memory allocation happens at all). This is done by just
+passing the size to the decomposition constructor, as in this example:
+\code
+HouseholderQR<MatrixXf> qr(50,50);
+MatrixXf A = MatrixXf::Random(50,50);
+qr.compute(A); // no dynamic memory allocation
+\endcode
+
+\section TutorialLinAlgRankRevealing Rank-revealing decompositions
+
+Certain decompositions are rank-revealing, i.e. are able to compute the rank of a matrix. These are typically
+also the decompositions that behave best in the face of a non-full-rank matrix (which in the square case means a
+singular matrix). On \ref TopicLinearAlgebraDecompositions "this table" you can see for all our decompositions
+whether they are rank-revealing or not.
+
+Rank-revealing decompositions offer at least a rank() method. They can also offer convenience methods such as isInvertible(),
+and some are also providing methods to compute the kernel (null-space) and image (column-space) of the matrix, as is the
+case with FullPivLU:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+  <td>\include TutorialLinAlgRankRevealing.cpp </td>
+  <td>\verbinclude TutorialLinAlgRankRevealing.out </td>
+</tr>
+</table>
+
+Of course, any rank computation depends on the choice of an arbitrary threshold, since practically no
+floating-point matrix is \em exactly rank-deficient. Eigen picks a sensible default threshold, which depends
+on the decomposition but is typically the diagonal size times machine epsilon. While this is the best default we
+could pick, only you know what is the right threshold for your application. You can set this by calling setThreshold()
+on your decomposition object before calling rank() or any other method that needs to use such a threshold.
+The decomposition itself, i.e. the compute() method, is independent of the threshold. You don't need to recompute the
+decomposition after you've changed the threshold.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+  <td>\include TutorialLinAlgSetThreshold.cpp </td>
+  <td>\verbinclude TutorialLinAlgSetThreshold.out </td>
+</tr>

+/** \eigenManualPage TutorialMapClass Interfacing with raw buffers: the Map class
+
+This page explains how to work with "raw" C/C++ arrays.
+This can be useful in a variety of contexts, particularly when "importing" vectors and matrices from other libraries into %Eigen.
+
+\eigenAutoToc
+
+\section TutorialMapIntroduction Introduction
+
+Occasionally you may have a pre-defined array of numbers that you want to use within %Eigen as a vector or matrix. While one option is to make a copy of the data, most commonly you probably want to re-use this memory as an %Eigen type. Fortunately, this is very easy with the Map class.
+
+\section TutorialMapTypes Map types and declaring Map variables
+
+A Map object has a type defined by its %Eigen equivalent:
+\code
+Map<Matrix<typename Scalar, int RowsAtCompileTime, int ColsAtCompileTime> >
+\endcode
+Note that, in this default case, a Map requires just a single template parameter.  
+
+To construct a Map variable, you need two other pieces of information: a pointer to the region of memory defining the array of coefficients, and the desired shape of the matrix or vector.  For example, to define a matrix of \c float with sizes determined at compile time, you might do the following:
+\code
+Map<MatrixXf> mf(pf,rows,columns);
+\endcode
+where \c pf is a \c float \c * pointing to the array of memory.  A fixed-size read-only vector of integers might be declared as
+\code
+Map<const Vector4i> mi(pi);
+\endcode
+where \c pi is an \c int \c *. In this case the size does not have to be passed to the constructor, because it is already specified by the Matrix/Array type.
+
+Note that Map does not have a default constructor; you \em must pass a pointer to intialize the object. However, you can work around this requirement (see \ref TutorialMapPlacementNew).
+
+Map is flexible enough to accomodate a variety of different data representations.  There are two other (optional) template parameters:
+\code
+Map<typename MatrixType,
+    int MapOptions,
+    typename StrideType>
+\endcode
+\li \c MapOptions specifies whether the pointer is \c #Aligned, or \c #Unaligned.  The default is \c #Unaligned.
+\li \c StrideType allows you to specify a custom layout for the memory array, using the Stride class.  One example would be to specify that the data array is organized in row-major format:
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+<td>\include Tutorial_Map_rowmajor.cpp </td>
+<td>\verbinclude Tutorial_Map_rowmajor.out </td>
+</table>
+However, Stride is even more flexible than this; for details, see the documentation for the Map and Stride classes.
+
+\section TutorialMapUsing Using Map variables
+
+You can use a Map object just like any other %Eigen type:
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+<td>\include Tutorial_Map_using.cpp </td>
+<td>\verbinclude Tutorial_Map_using.out </td>
+</table>
+
+All %Eigen functions are written to accept Map objects just like other %Eigen types. However, when writing your own functions taking %Eigen types, this does \em not happen automatically: a Map type is not identical to its Dense equivalent.  See \ref TopicFunctionTakingEigenTypes for details.
+
+\section TutorialMapPlacementNew Changing the mapped array
+
+It is possible to change the array of a Map object after declaration, using the C++ "placement new" syntax:
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+<td>\include Map_placement_new.cpp </td>
+<td>\verbinclude Map_placement_new.out </td>
+</table>
+Despite appearances, this does not invoke the memory allocator, because the syntax specifies the location for storing the result.
+
+This syntax makes it possible to declare a Map object without first knowing the mapped array's location in memory:
+\code
+Map<Matrix3f> A(NULL);  // don't try to use this matrix yet!
+VectorXf b(n_matrices);
+for (int i = 0; i < n_matrices; i++)
+{
+  new (&A) Map<Matrix3f>(get_matrix_pointer(i));
+  b(i) = A.trace();
+}
+\endcode

+/** \eigenManualPage TutorialMatrixArithmetic Matrix and vector arithmetic
+
+This page aims to provide an overview and some details on how to perform arithmetic
+between matrices, vectors and scalars with Eigen.
+
+\eigenAutoToc
+
+\section TutorialArithmeticIntroduction Introduction
+
+Eigen offers matrix/vector arithmetic operations either through overloads of common C++ arithmetic operators such as +, -, *,
+or through special methods such as dot(), cross(), etc.
+For the Matrix class (matrices and vectors), operators are only overloaded to support
+linear-algebraic operations. For example, \c matrix1 \c * \c matrix2 means matrix-matrix product,
+and \c vector \c + \c scalar is just not allowed. If you want to perform all kinds of array operations,
+not linear algebra, see the \ref TutorialArrayClass "next page".
+
+\section TutorialArithmeticAddSub Addition and subtraction
+
+The left hand side and right hand side must, of course, have the same numbers of rows and of columns. They must
+also have the same \c Scalar type, as Eigen doesn't do automatic type promotion. The operators at hand here are:
+\li binary operator + as in \c a+b
+\li binary operator - as in \c a-b
+\li unary operator - as in \c -a
+\li compound operator += as in \c a+=b
+\li compound operator -= as in \c a-=b
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include tut_arithmetic_add_sub.cpp
+</td>
+<td>
+\verbinclude tut_arithmetic_add_sub.out
+</td></tr></table>
+
+\section TutorialArithmeticScalarMulDiv Scalar multiplication and division
+
+Multiplication and division by a scalar is very simple too. The operators at hand here are:
+\li binary operator * as in \c matrix*scalar
+\li binary operator * as in \c scalar*matrix
+\li binary operator / as in \c matrix/scalar
+\li compound operator *= as in \c matrix*=scalar
+\li compound operator /= as in \c matrix/=scalar
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include tut_arithmetic_scalar_mul_div.cpp
+</td>
+<td>
+\verbinclude tut_arithmetic_scalar_mul_div.out
+</td></tr></table>
+
+
+\section TutorialArithmeticMentionXprTemplates A note about expression templates
+
+This is an advanced topic that we explain on \ref TopicEigenExpressionTemplates "this page",
+but it is useful to just mention it now. In Eigen, arithmetic operators such as \c operator+ don't
+perform any computation by themselves, they just return an "expression object" describing the computation to be
+performed. The actual computation happens later, when the whole expression is evaluated, typically in \c operator=.
+While this might sound heavy, any modern optimizing compiler is able to optimize away that abstraction and
+the result is perfectly optimized code. For example, when you do:
+\code
+VectorXf a(50), b(50), c(50), d(50);
+...
+a = 3*b + 4*c + 5*d;
+\endcode
+Eigen compiles it to just one for loop, so that the arrays are traversed only once. Simplifying (e.g. ignoring
+SIMD optimizations), this loop looks like this:
+\code
+for(int i = 0; i < 50; ++i)
+  a[i] = 3*b[i] + 4*c[i] + 5*d[i];
+\endcode
+Thus, you should not be afraid of using relatively large arithmetic expressions with Eigen: it only gives Eigen
+more opportunities for optimization.
+
+\section TutorialArithmeticTranspose Transposition and conjugation
+
+The transpose \f$ a^T \f$, conjugate \f$ \bar{a} \f$, and adjoint (i.e., conjugate transpose) \f$ a^* \f$ of a matrix or vector \f$ a \f$ are obtained by the member functions \link DenseBase::transpose() transpose()\endlink, \link MatrixBase::conjugate() conjugate()\endlink, and \link MatrixBase::adjoint() adjoint()\endlink, respectively.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include tut_arithmetic_transpose_conjugate.cpp
+</td>
+<td>
+\verbinclude tut_arithmetic_transpose_conjugate.out
+</td></tr></table>
+
+For real matrices, \c conjugate() is a no-operation, and so \c adjoint() is equivalent to \c transpose().
+
+As for basic arithmetic operators, \c transpose() and \c adjoint() simply return a proxy object without doing the actual transposition. If you do <tt>b = a.transpose()</tt>, then the transpose is evaluated at the same time as the result is written into \c b. However, there is a complication here. If you do <tt>a = a.transpose()</tt>, then Eigen starts writing the result into \c a before the evaluation of the transpose is finished. Therefore, the instruction <tt>a = a.transpose()</tt> does not replace \c a with its transpose, as one would expect:
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include tut_arithmetic_transpose_aliasing.cpp
+</td>
+<td>
+\verbinclude tut_arithmetic_transpose_aliasing.out
+</td></tr></table>
+This is the so-called \ref TopicAliasing "aliasing issue". In "debug mode", i.e., when \ref TopicAssertions "assertions" have not been disabled, such common pitfalls are automatically detected. 
+
+For \em in-place transposition, as for instance in <tt>a = a.transpose()</tt>, simply use the \link DenseBase::transposeInPlace() transposeInPlace()\endlink  function:
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include tut_arithmetic_transpose_inplace.cpp
+</td>
+<td>
+\verbinclude tut_arithmetic_transpose_inplace.out
+</td></tr></table>
+There is also the \link MatrixBase::adjointInPlace() adjointInPlace()\endlink function for complex matrices.
+
+\section TutorialArithmeticMatrixMul Matrix-matrix and matrix-vector multiplication
+
+Matrix-matrix multiplication is again done with \c operator*. Since vectors are a special
+case of matrices, they are implicitly handled there too, so matrix-vector product is really just a special
+case of matrix-matrix product, and so is vector-vector outer product. Thus, all these cases are handled by just
+two operators:
+\li binary operator * as in \c a*b
+\li compound operator *= as in \c a*=b (this multiplies on the right: \c a*=b is equivalent to <tt>a = a*b</tt>)
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include tut_arithmetic_matrix_mul.cpp
+</td>
+<td>
+\verbinclude tut_arithmetic_matrix_mul.out
+</td></tr></table>
+
+Note: if you read the above paragraph on expression templates and are worried that doing \c m=m*m might cause
+aliasing issues, be reassured for now: Eigen treats matrix multiplication as a special case and takes care of
+introducing a temporary here, so it will compile \c m=m*m as:
+\code
+tmp = m*m;
+m = tmp;
+\endcode
+If you know your matrix product can be safely evaluated into the destination matrix without aliasing issue, then you can use the \link MatrixBase::noalias() noalias()\endlink function to avoid the temporary, e.g.:
+\code
+c.noalias() += a * b;
+\endcode
+For more details on this topic, see the page on \ref TopicAliasing "aliasing".
+
+\b Note: for BLAS users worried about performance, expressions such as <tt>c.noalias() -= 2 * a.adjoint() * b;</tt> are fully optimized and trigger a single gemm-like function call.
+
+\section TutorialArithmeticDotAndCross Dot product and cross product
+
+For dot product and cross product, you need the \link MatrixBase::dot() dot()\endlink and \link MatrixBase::cross() cross()\endlink methods. Of course, the dot product can also be obtained as a 1x1 matrix as u.adjoint()*v.
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include tut_arithmetic_dot_cross.cpp
+</td>
+<td>
+\verbinclude tut_arithmetic_dot_cross.out
+</td></tr></table>
+
+Remember that cross product is only for vectors of size 3. Dot product is for vectors of any sizes.
+When using complex numbers, Eigen's dot product is conjugate-linear in the first variable and linear in the
+second variable.
+
+\section TutorialArithmeticRedux Basic arithmetic reduction operations
+Eigen also provides some reduction operations to reduce a given matrix or vector to a single value such as the sum (computed by \link DenseBase::sum() sum()\endlink), product (\link DenseBase::prod() prod()\endlink), or the maximum (\link DenseBase::maxCoeff() maxCoeff()\endlink) and minimum (\link DenseBase::minCoeff() minCoeff()\endlink) of all its coefficients.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include tut_arithmetic_redux_basic.cpp
+</td>
+<td>
+\verbinclude tut_arithmetic_redux_basic.out
+</td></tr></table>
+
+The \em trace of a matrix, as returned by the function \link MatrixBase::trace() trace()\endlink, is the sum of the diagonal coefficients and can also be computed as efficiently using <tt>a.diagonal().sum()</tt>, as we will see later on.
+
+There also exist variants of the \c minCoeff and \c maxCoeff functions returning the coordinates of the respective coefficient via the arguments:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include tut_arithmetic_redux_minmax.cpp
+</td>
+<td>
+\verbinclude tut_arithmetic_redux_minmax.out
+</td></tr></table>
+
+
+\section TutorialArithmeticValidity Validity of operations
+Eigen checks the validity of the operations that you perform. When possible,
+it checks them at compile time, producing compilation errors. These error messages can be long and ugly,
+but Eigen writes the important message in UPPERCASE_LETTERS_SO_IT_STANDS_OUT. For example:
+\code
+  Matrix3f m;
+  Vector4f v;
+  v = m*v;      // Compile-time error: YOU_MIXED_MATRICES_OF_DIFFERENT_SIZES
+\endcode
+
+Of course, in many cases, for example when checking dynamic sizes, the check cannot be performed at compile time.
+Eigen then uses runtime assertions. This means that the program will abort with an error message when executing an illegal operation if it is run in "debug mode", and it will probably crash if assertions are turned off.
+
+\code
+  MatrixXf m(3,3);
+  VectorXf v(4);
+  v = m * v; // Run-time assertion failure here: "invalid matrix product"
+\endcode
+
+For more details on this topic, see \ref TopicAssertions "this page".

+/** \eigenManualPage TutorialMatrixClass The Matrix class
+
+\eigenAutoToc
+
+In Eigen, all matrices and vectors are objects of the Matrix template class.
+Vectors are just a special case of matrices, with either 1 row or 1 column.
+
+\section TutorialMatrixFirst3Params The first three template parameters of Matrix
+
+The Matrix class takes six template parameters, but for now it's enough to
+learn about the first three first parameters. The three remaining parameters have default
+values, which for now we will leave untouched, and which we
+\ref TutorialMatrixOptTemplParams "discuss below".
+
+The three mandatory template parameters of Matrix are:
+\code
+Matrix<typename Scalar, int RowsAtCompileTime, int ColsAtCompileTime>
+\endcode
+\li \c Scalar is the scalar type, i.e. the type of the coefficients.
+    That is, if you want a matrix of floats, choose \c float here.
+    See \ref TopicScalarTypes "Scalar types" for a list of all supported
+    scalar types and for how to extend support to new types.
+\li \c RowsAtCompileTime and \c ColsAtCompileTime are the number of rows
+    and columns of the matrix as known at compile time (see 
+    \ref TutorialMatrixDynamic "below" for what to do if the number is not
+    known at compile time).
+
+We offer a lot of convenience typedefs to cover the usual cases. For example, \c Matrix4f is
+a 4x4 matrix of floats. Here is how it is defined by Eigen:
+\code
+typedef Matrix<float, 4, 4> Matrix4f;
+\endcode
+We discuss \ref TutorialMatrixTypedefs "below" these convenience typedefs.
+
+\section TutorialMatrixVectors Vectors
+
+As mentioned above, in Eigen, vectors are just a special case of
+matrices, with either 1 row or 1 column. The case where they have 1 column is the most common;
+such vectors are called column-vectors, often abbreviated as just vectors. In the other case
+where they have 1 row, they are called row-vectors.
+
+For example, the convenience typedef \c Vector3f is a (column) vector of 3 floats. It is defined as follows by Eigen:
+\code
+typedef Matrix<float, 3, 1> Vector3f;
+\endcode
+We also offer convenience typedefs for row-vectors, for example:
+\code
+typedef Matrix<int, 1, 2> RowVector2i;
+\endcode
+
+\section TutorialMatrixDynamic The special value Dynamic
+
+Of course, Eigen is not limited to matrices whose dimensions are known at compile time.
+The \c RowsAtCompileTime and \c ColsAtCompileTime template parameters can take the special
+value \c Dynamic which indicates that the size is unknown at compile time, so must
+be handled as a run-time variable. In Eigen terminology, such a size is referred to as a
+\em dynamic \em size; while a size that is known at compile time is called a
+\em fixed \em size. For example, the convenience typedef \c MatrixXd, meaning
+a matrix of doubles with dynamic size, is defined as follows:
+\code
+typedef Matrix<double, Dynamic, Dynamic> MatrixXd;
+\endcode
+And similarly, we define a self-explanatory typedef \c VectorXi as follows:
+\code
+typedef Matrix<int, Dynamic, 1> VectorXi;
+\endcode
+You can perfectly have e.g. a fixed number of rows with a dynamic number of columns, as in:
+\code
+Matrix<float, 3, Dynamic>
+\endcode
+
+\section TutorialMatrixConstructors Constructors
+
+A default constructor is always available, never performs any dynamic memory allocation, and never initializes the matrix coefficients. You can do:
+\code
+Matrix3f a;
+MatrixXf b;
+\endcode
+Here,
+\li \c a is a 3-by-3 matrix, with a plain float[9] array of uninitialized coefficients,
+\li \c b is a dynamic-size matrix whose size is currently 0-by-0, and whose array of
+coefficients hasn't yet been allocated at all.
+
+Constructors taking sizes are also available. For matrices, the number of rows is always passed first.
+For vectors, just pass the vector size. They allocate the array of coefficients
+with the given size, but don't initialize the coefficients themselves:
+\code
+MatrixXf a(10,15);
+VectorXf b(30);
+\endcode
+Here,
+\li \c a is a 10x15 dynamic-size matrix, with allocated but currently uninitialized coefficients.
+\li \c b is a dynamic-size vector of size 30, with allocated but currently uninitialized coefficients.
+
+In order to offer a uniform API across fixed-size and dynamic-size matrices, it is legal to use these
+constructors on fixed-size matrices, even if passing the sizes is useless in this case. So this is legal:
+\code
+Matrix3f a(3,3);
+\endcode
+and is a no-operation.
+
+Finally, we also offer some constructors to initialize the coefficients of small fixed-size vectors up to size 4:
+\code
+Vector2d a(5.0, 6.0);
+Vector3d b(5.0, 6.0, 7.0);
+Vector4d c(5.0, 6.0, 7.0, 8.0);
+\endcode
+
+\section TutorialMatrixCoeffAccessors Coefficient accessors
+
+The primary coefficient accessors and mutators in Eigen are the overloaded parenthesis operators.
+For matrices, the row index is always passed first. For vectors, just pass one index.
+The numbering starts at 0. This example is self-explanatory:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include tut_matrix_coefficient_accessors.cpp
+</td>
+<td>
+\verbinclude tut_matrix_coefficient_accessors.out
+</td></tr></table>
+
+Note that the syntax <tt> m(index) </tt>
+is not restricted to vectors, it is also available for general matrices, meaning index-based access
+in the array of coefficients. This however depends on the matrix's storage order. All Eigen matrices default to
+column-major storage order, but this can be changed to row-major, see \ref TopicStorageOrders "Storage orders".
+
+The operator[] is also overloaded for index-based access in vectors, but keep in mind that C++ doesn't allow operator[] to
+take more than one argument. We restrict operator[] to vectors, because an awkwardness in the C++ language
+would make matrix[i,j] compile to the same thing as matrix[j] !
+
+\section TutorialMatrixCommaInitializer Comma-initialization
+
+%Matrix and vector coefficients can be conveniently set using the so-called \em comma-initializer syntax.
+For now, it is enough to know this example:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+<td>\include Tutorial_commainit_01.cpp </td>
+<td>\verbinclude Tutorial_commainit_01.out </td>
+</tr></table>
+
+
+The right-hand side can also contain matrix expressions as discussed in \ref TutorialAdvancedInitialization "this page".
+
+\section TutorialMatrixSizesResizing Resizing
+
+The current size of a matrix can be retrieved by \link EigenBase::rows() rows()\endlink, \link EigenBase::cols() cols() \endlink and \link EigenBase::size() size()\endlink. These methods return the number of rows, the number of columns and the number of coefficients, respectively. Resizing a dynamic-size matrix is done by the \link PlainObjectBase::resize(Index,Index) resize() \endlink method.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+<td>\include tut_matrix_resize.cpp </td>
+<td>\verbinclude tut_matrix_resize.out </td>
+</tr></table>
+
+The resize() method is a no-operation if the actual matrix size doesn't change; otherwise it is destructive: the values of the coefficients may change.
+If you want a conservative variant of resize() which does not change the coefficients, use \link PlainObjectBase::conservativeResize() conservativeResize()\endlink, see \ref TopicResizing "this page" for more details.
+
+All these methods are still available on fixed-size matrices, for the sake of API uniformity. Of course, you can't actually
+resize a fixed-size matrix. Trying to change a fixed size to an actually different value will trigger an assertion failure;
+but the following code is legal:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+<td>\include tut_matrix_resize_fixed_size.cpp </td>
+<td>\verbinclude tut_matrix_resize_fixed_size.out </td>
+</tr></table>
+
+
+\section TutorialMatrixAssignment Assignment and resizing
+
+Assignment is the action of copying a matrix into another, using \c operator=. Eigen resizes the matrix on the left-hand side automatically so that it matches the size of the matrix on the right-hand size. For example:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr>
+<td>\include tut_matrix_assignment_resizing.cpp </td>
+<td>\verbinclude tut_matrix_assignment_resizing.out </td>
+</tr></table>
+
+Of course, if the left-hand side is of fixed size, resizing it is not allowed.
+
+If you do not want this automatic resizing to happen (for example for debugging purposes), you can disable it, see
+\ref TopicResizing "this page".
+
+
+\section TutorialMatrixFixedVsDynamic Fixed vs. Dynamic size
+
+When should one use fixed sizes (e.g. \c Matrix4f), and when should one prefer dynamic sizes (e.g. \c MatrixXf)?
+The simple answer is: use fixed
+sizes for very small sizes where you can, and use dynamic sizes for larger sizes or where you have to. For small sizes,
+especially for sizes smaller than (roughly) 16, using fixed sizes is hugely beneficial
+to performance, as it allows Eigen to avoid dynamic memory allocation and to unroll
+loops. Internally, a fixed-size Eigen matrix is just a plain array, i.e. doing
+\code Matrix4f mymatrix; \endcode
+really amounts to just doing
+\code float mymatrix[16]; \endcode
+so this really has zero runtime cost. By contrast, the array of a dynamic-size matrix
+is always allocated on the heap, so doing
+\code MatrixXf mymatrix(rows,columns); \endcode
+amounts to doing
+\code float *mymatrix = new float[rows*columns]; \endcode
+and in addition to that, the MatrixXf object stores its number of rows and columns as
+member variables.
+
+The limitation of using fixed sizes, of course, is that this is only possible
+when you know the sizes at compile time. Also, for large enough sizes, say for sizes
+greater than (roughly) 32, the performance benefit of using fixed sizes becomes negligible.
+Worse, trying to create a very large matrix using fixed sizes inside a function could result in a
+stack overflow, since Eigen will try to allocate the array automatically as a local variable, and
+this is normally done on the stack.
+Finally, depending on circumstances, Eigen can also be more aggressive trying to vectorize
+(use SIMD instructions) when dynamic sizes are used, see \ref TopicVectorization "Vectorization".
+
+\section TutorialMatrixOptTemplParams Optional template parameters
+
+We mentioned at the beginning of this page that the Matrix class takes six template parameters,
+but so far we only discussed the first three. The remaining three parameters are optional. Here is
+the complete list of template parameters:
+\code
+Matrix<typename Scalar,
+       int RowsAtCompileTime,
+       int ColsAtCompileTime,
+       int Options = 0,
+       int MaxRowsAtCompileTime = RowsAtCompileTime,
+       int MaxColsAtCompileTime = ColsAtCompileTime>
+\endcode
+\li \c Options is a bit field. Here, we discuss only one bit: \c RowMajor. It specifies that the matrices
+      of this type use row-major storage order; by default, the storage order is column-major. See the page on
+      \ref TopicStorageOrders "storage orders". For example, this type means row-major 3x3 matrices:
+      \code
+      Matrix<float, 3, 3, RowMajor>
+      \endcode
+\li \c MaxRowsAtCompileTime and \c MaxColsAtCompileTime are useful when you want to specify that, even though
+      the exact sizes of your matrices are not known at compile time, a fixed upper bound is known at
+      compile time. The biggest reason why you might want to do that is to avoid dynamic memory allocation.
+      For example the following matrix type uses a plain array of 12 floats, without dynamic memory allocation:
+      \code
+      Matrix<float, Dynamic, Dynamic, 0, 3, 4>
+      \endcode
+
+\section TutorialMatrixTypedefs Convenience typedefs
+
+Eigen defines the following Matrix typedefs:
+\li MatrixNt for Matrix<type, N, N>. For example, MatrixXi for Matrix<int, Dynamic, Dynamic>.
+\li VectorNt for Matrix<type, N, 1>. For example, Vector2f for Matrix<float, 2, 1>.
+\li RowVectorNt for Matrix<type, 1, N>. For example, RowVector3d for Matrix<double, 1, 3>.
+
+Where:
+\li N can be any one of \c 2, \c 3, \c 4, or \c X (meaning \c Dynamic).
+\li t can be any one of \c i (meaning int), \c f (meaning float), \c d (meaning double),
+      \c cf (meaning complex<float>), or \c cd (meaning complex<double>). The fact that typedefs are only
+    defined for these five types doesn't mean that they are the only supported scalar types. For example,
+    all standard integer types are supported, see \ref TopicScalarTypes "Scalar types".

+
+This page explains Eigen's reductions, visitors and broadcasting and how they are used with
+\link MatrixBase matrices \endlink and \link ArrayBase arrays \endlink.
+
+\eigenAutoToc
+
+\section TutorialReductionsVisitorsBroadcastingReductions Reductions
+In Eigen, a reduction is a function taking a matrix or array, and returning a single
+scalar value. One of the most used reductions is \link DenseBase::sum() .sum() \endlink,
+returning the sum of all the coefficients inside a given matrix or array.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include tut_arithmetic_redux_basic.cpp
+</td>
+<td>
+\verbinclude tut_arithmetic_redux_basic.out
+</td></tr></table>
+
+The \em trace of a matrix, as returned by the function \c trace(), is the sum of the diagonal coefficients and can equivalently be computed <tt>a.diagonal().sum()</tt>.
+
+
+\subsection TutorialReductionsVisitorsBroadcastingReductionsNorm Norm computations
+
+The (Euclidean a.k.a. \f$\ell^2\f$) squared norm of a vector can be obtained \link MatrixBase::squaredNorm() squaredNorm() \endlink. It is equal to the dot product of the vector by itself, and equivalently to the sum of squared absolute values of its coefficients.
+
+Eigen also provides the \link MatrixBase::norm() norm() \endlink method, which returns the square root of \link MatrixBase::squaredNorm() squaredNorm() \endlink.
+
+These operations can also operate on matrices; in that case, a n-by-p matrix is seen as a vector of size (n*p), so for example the \link MatrixBase::norm() norm() \endlink method returns the "Frobenius" or "Hilbert-Schmidt" norm. We refrain from speaking of the \f$\ell^2\f$ norm of a matrix because that can mean different things.
+
+If you want other coefficient-wise \f$\ell^p\f$ norms, use the \link MatrixBase::lpNorm lpNorm<p>() \endlink method. The template parameter \a p can take the special value \a Infinity if you want the \f$\ell^\infty\f$ norm, which is the maximum of the absolute values of the coefficients.
+
+The following example demonstrates these methods.
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ReductionsVisitorsBroadcasting_reductions_norm.cpp
+</td>
+<td>
+\verbinclude Tutorial_ReductionsVisitorsBroadcasting_reductions_norm.out
+</td></tr></table>
+
+\b Operator \b norm: The 1-norm and \f$\infty\f$-norm <a href="https://en.wikipedia.org/wiki/Operator_norm">matrix operator norms</a> can easily be computed as follows:
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ReductionsVisitorsBroadcasting_reductions_operatornorm.cpp
+</td>
+<td>
+\verbinclude Tutorial_ReductionsVisitorsBroadcasting_reductions_operatornorm.out
+</td></tr></table>
+See below for more explanations on the syntax of these expressions.
+
+\subsection TutorialReductionsVisitorsBroadcastingReductionsBool Boolean reductions
+
+The following reductions operate on boolean values:
+  - \link DenseBase::all() all() \endlink returns \b true if all of the coefficients in a given Matrix or Array evaluate to \b true .
+  - \link DenseBase::any() any() \endlink returns \b true if at least one of the coefficients in a given Matrix or Array evaluates to \b true .
+  - \link DenseBase::count() count() \endlink returns the number of coefficients in a given Matrix or Array that evaluate to  \b true.
+
+These are typically used in conjunction with the coefficient-wise comparison and equality operators provided by Array. For instance, <tt>array > 0</tt> is an %Array of the same size as \c array , with \b true at those positions where the corresponding coefficient of \c array is positive. Thus, <tt>(array > 0).all()</tt> tests whether all coefficients of \c array are positive. This can be seen in the following example:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ReductionsVisitorsBroadcasting_reductions_bool.cpp
+</td>
+<td>
+\verbinclude Tutorial_ReductionsVisitorsBroadcasting_reductions_bool.out
+</td></tr></table>
+
+\subsection TutorialReductionsVisitorsBroadcastingReductionsUserdefined User defined reductions
+
+TODO
+
+In the meantime you can have a look at the DenseBase::redux() function.
+
+\section TutorialReductionsVisitorsBroadcastingVisitors Visitors
+Visitors are useful when one wants to obtain the location of a coefficient inside 
+a Matrix or Array. The simplest examples are 
+\link MatrixBase::maxCoeff() maxCoeff(&x,&y) \endlink and 
+\link MatrixBase::minCoeff() minCoeff(&x,&y)\endlink, which can be used to find
+the location of the greatest or smallest coefficient in a Matrix or 
+Array.
+
+The arguments passed to a visitor are pointers to the variables where the
+row and column position are to be stored. These variables should be of type
+\link Eigen::Index Index \endlink, as shown below:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ReductionsVisitorsBroadcasting_visitors.cpp
+</td>
+<td>
+\verbinclude Tutorial_ReductionsVisitorsBroadcasting_visitors.out
+</td></tr></table>
+
+Both functions also return the value of the minimum or maximum coefficient.
+
+\section TutorialReductionsVisitorsBroadcastingPartialReductions Partial reductions
+Partial reductions are reductions that can operate column- or row-wise on a Matrix or 
+Array, applying the reduction operation on each column or row and 
+returning a column or row vector with the corresponding values. Partial reductions are applied 
+with \link DenseBase::colwise() colwise() \endlink or \link DenseBase::rowwise() rowwise() \endlink.
+
+A simple example is obtaining the maximum of the elements 
+in each column in a given matrix, storing the result in a row vector:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ReductionsVisitorsBroadcasting_colwise.cpp
+</td>
+<td>
+\verbinclude Tutorial_ReductionsVisitorsBroadcasting_colwise.out
+</td></tr></table>
+
+The same operation can be performed row-wise:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ReductionsVisitorsBroadcasting_rowwise.cpp
+</td>
+<td>
+\verbinclude Tutorial_ReductionsVisitorsBroadcasting_rowwise.out
+</td></tr></table>
+
+<b>Note that column-wise operations return a row vector, while row-wise operations return a column vector.</b>
+
+\subsection TutorialReductionsVisitorsBroadcastingPartialReductionsCombined Combining partial reductions with other operations
+It is also possible to use the result of a partial reduction to do further processing.
+Here is another example that finds the column whose sum of elements is the maximum
+ within a matrix. With column-wise partial reductions this can be coded as:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ReductionsVisitorsBroadcasting_maxnorm.cpp
+</td>
+<td>
+\verbinclude Tutorial_ReductionsVisitorsBroadcasting_maxnorm.out
+</td></tr></table>
+
+The previous example applies the \link DenseBase::sum() sum() \endlink reduction on each column
+though the \link DenseBase::colwise() colwise() \endlink visitor, obtaining a new matrix whose
+size is 1x4.
+
+Therefore, if
+\f[
+\mbox{m} = \begin{bmatrix} 1 & 2 & 6 & 9 \\
+                    3 & 1 & 7 & 2 \end{bmatrix}
+\f]
+
+then
+
+\f[
+\mbox{m.colwise().sum()} = \begin{bmatrix} 4 & 3 & 13 & 11 \end{bmatrix}
+\f]
+
+The \link DenseBase::maxCoeff() maxCoeff() \endlink reduction is finally applied 
+to obtain the column index where the maximum sum is found, 
+which is the column index 2 (third column) in this case.
+
+
+\section TutorialReductionsVisitorsBroadcastingBroadcasting Broadcasting
+The concept behind broadcasting is similar to partial reductions, with the difference that broadcasting 
+constructs an expression where a vector (column or row) is interpreted as a matrix by replicating it in 
+one direction.
+
+A simple example is to add a certain column vector to each column in a matrix. 
+This can be accomplished with:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ReductionsVisitorsBroadcasting_broadcast_simple.cpp
+</td>
+<td>
+\verbinclude Tutorial_ReductionsVisitorsBroadcasting_broadcast_simple.out
+</td></tr></table>
+
+We can interpret the instruction <tt>mat.colwise() += v</tt> in two equivalent ways. It adds the vector \c v
+to every column of the matrix. Alternatively, it can be interpreted as repeating the vector \c v four times to
+form a four-by-two matrix which is then added to \c mat:
+\f[
+\begin{bmatrix} 1 & 2 & 6 & 9 \\ 3 & 1 & 7 & 2 \end{bmatrix}
++ \begin{bmatrix} 0 & 0 & 0 & 0 \\ 1 & 1 & 1 & 1 \end{bmatrix}
+= \begin{bmatrix} 1 & 2 & 6 & 9 \\ 4 & 2 & 8 & 3 \end{bmatrix}.
+\f]
+The operators <tt>-=</tt>, <tt>+</tt> and <tt>-</tt> can also be used column-wise and row-wise. On arrays, we 
+can also use the operators <tt>*=</tt>, <tt>/=</tt>, <tt>*</tt> and <tt>/</tt> to perform coefficient-wise 
+multiplication and division column-wise or row-wise. These operators are not available on matrices because it
+is not clear what they would do. If you want multiply column 0 of a matrix \c mat with \c v(0), column 1 with 
+\c v(1), and so on, then use <tt>mat = mat * v.asDiagonal()</tt>.
+
+It is important to point out that the vector to be added column-wise or row-wise must be of type Vector,
+and cannot be a Matrix. If this is not met then you will get compile-time error. This also means that
+broadcasting operations can only be applied with an object of type Vector, when operating with Matrix.
+The same applies for the Array class, where the equivalent for VectorXf is ArrayXf. As always, you should
+not mix arrays and matrices in the same expression.
+
+To perform the same operation row-wise we can do:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ReductionsVisitorsBroadcasting_broadcast_simple_rowwise.cpp
+</td>
+<td>
+\verbinclude Tutorial_ReductionsVisitorsBroadcasting_broadcast_simple_rowwise.out
+</td></tr></table>
+
+\subsection TutorialReductionsVisitorsBroadcastingBroadcastingCombined Combining broadcasting with other operations
+Broadcasting can also be combined with other operations, such as Matrix or Array operations, 
+reductions and partial reductions.
+
+Now that broadcasting, reductions and partial reductions have been introduced, we can dive into a more advanced example that finds
+the nearest neighbour of a vector <tt>v</tt> within the columns of matrix <tt>m</tt>. The Euclidean distance will be used in this example,
+computing the squared Euclidean distance with the partial reduction named \link MatrixBase::squaredNorm() squaredNorm() \endlink:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ReductionsVisitorsBroadcasting_broadcast_1nn.cpp
+</td>
+<td>
+\verbinclude Tutorial_ReductionsVisitorsBroadcasting_broadcast_1nn.out
+</td></tr></table>
+
+The line that does the job is 
+\code
+  (m.colwise() - v).colwise().squaredNorm().minCoeff(&index);
+\endcode
+
+We will go step by step to understand what is happening:
+
+  - <tt>m.colwise() - v</tt> is a broadcasting operation, subtracting <tt>v</tt> from each column in <tt>m</tt>. The result of this operation
+is a new matrix whose size is the same as matrix <tt>m</tt>: \f[
+  \mbox{m.colwise() - v} = 
+  \begin{bmatrix}
+    -1 & 21 & 4 & 7 \\
+     0 & 8  & 4 & -1
+  \end{bmatrix}
+\f]
+
+  - <tt>(m.colwise() - v).colwise().squaredNorm()</tt> is a partial reduction, computing the squared norm column-wise. The result of
+this operation is a row vector where each coefficient is the squared Euclidean distance between each column in <tt>m</tt> and <tt>v</tt>: \f[
+  \mbox{(m.colwise() - v).colwise().squaredNorm()} =
+  \begin{bmatrix}
+     1 & 505 & 32 & 50
+  \end{bmatrix}
+\f]
+
+  - Finally, <tt>minCoeff(&index)</tt> is used to obtain the index of the column in <tt>m</tt> that is closest to <tt>v</tt> in terms of Euclidean
+distance.

+
+%Eigen does not expose convenient methods to take slices or to reshape a matrix yet.
+Nonetheless, such features can easily be emulated using the Map class.
+
+\eigenAutoToc
+
+\section TutorialReshape Reshape
+
+A reshape operation consists in modifying the sizes of a matrix while keeping the same coefficients.
+Instead of modifying the input matrix itself, which is not possible for compile-time sizes, the approach consist in creating a different \em view on the storage using class Map.
+Here is a typical example creating a 1D linear view of a matrix:
+
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ReshapeMat2Vec.cpp
+</td>
+<td>
+\verbinclude Tutorial_ReshapeMat2Vec.out
+</td></tr></table>
+
+Remark how the storage order of the input matrix modifies the order of the coefficients in the linear view.
+Here is another example reshaping a 2x6 matrix to a 6x2 one:
+<table class="example">
+<tr><th>Example:</th><th>Output:</th></tr>
+<tr><td>
+\include Tutorial_ReshapeMat2Mat.cpp
+</td>
+<td>
+\verbinclude Tutorial_ReshapeMat2Mat.out
+</td></tr></table>
+
+
+
+\section TutorialSlicing Slicing
+
+Slicing consists in taking a set of rows, columns, or elements, uniformly spaced within a matrix.
+Again, the class Map allows to easily mimic this feature.
+
+For instance, one can skip every P elements in a vector:
+<table class="example">

+
+One can olso take one column over three using an adequate outer-stride or inner-stride depending on the actual storage order:

+\section TutorialSparseIntro Sparse matrix format
+
+In many applications (e.g., finite element methods) it is common to deal with very large matrices where only a few coefficients are different from zero.  In such cases, memory consumption can be reduced and performance increased by using a specialized representation storing only the nonzero coefficients. Such a matrix is called a sparse matrix.
+
+\b The \b %SparseMatrix \b class
+
+The class SparseMatrix is the main sparse matrix representation of Eigen's sparse module; it offers high performance and low memory usage.
+It implements a more versatile variant of the widely-used Compressed Column (or Row) Storage scheme.
+It consists of four compact arrays:
+ - \c Values: stores the coefficient values of the non-zeros.
+ - \c InnerIndices: stores the row (resp. column) indices of the non-zeros.
+ - \c OuterStarts: stores for each column (resp. row) the index of the first non-zero in the previous two arrays.
+ - \c InnerNNZs: stores the number of non-zeros of each column (resp. row).
+The word \c inner refers to an \em inner \em vector that is a column for a column-major matrix, or a row for a row-major matrix.
+The word \c outer refers to the other direction.
+
+This storage scheme is better explained on an example. The following matrix
+<table class="manual">
+<tr><td> 0</td><td>3</td><td> 0</td><td>0</td><td> 0</td></tr>
+<tr><td>22</td><td>0</td><td> 0</td><td>0</td><td>17</td></tr>
+<tr><td> 7</td><td>5</td><td> 0</td><td>1</td><td> 0</td></tr>
+<tr><td> 0</td><td>0</td><td> 0</td><td>0</td><td> 0</td></tr>
+<tr><td> 0</td><td>0</td><td>14</td><td>0</td><td> 8</td></tr>
+</table>
+
+and one of its possible sparse, \b column \b major representation:
+<table class="manual">
+<tr><td>Values:</td>        <td>22</td><td>7</td><td>_</td><td>3</td><td>5</td><td>14</td><td>_</td><td>_</td><td>1</td><td>_</td><td>17</td><td>8</td></tr>
+<tr><td>InnerIndices:</td>  <td> 1</td><td>2</td><td>_</td><td>0</td><td>2</td><td> 4</td><td>_</td><td>_</td><td>2</td><td>_</td><td> 1</td><td>4</td></tr>
+</table>
+<table class="manual">
+<tr><td>OuterStarts:</td><td>0</td><td>3</td><td>5</td><td>8</td><td>10</td><td>\em 12 </td></tr>
+<tr><td>InnerNNZs:</td>    <td>2</td><td>2</td><td>1</td><td>1</td><td> 2</td><td></td></tr>
+</table>
+
+Currently the elements of a given inner vector are guaranteed to be always sorted by increasing inner indices.
+The \c "_" indicates available free space to quickly insert new elements.
+Assuming no reallocation is needed, the insertion of a random element is therefore in O(nnz_j) where nnz_j is the number of nonzeros of the respective inner vector.
+On the other hand, inserting elements with increasing inner indices in a given inner vector is much more efficient since this only requires to increase the respective \c InnerNNZs entry that is a O(1) operation.
+
+The case where no empty space is available is a special case, and is refered as the \em compressed mode.
+It corresponds to the widely used Compressed Column (or Row) Storage schemes (CCS or CRS).
+Any SparseMatrix can be turned to this form by calling the SparseMatrix::makeCompressed() function.
+In this case, one can remark that the \c InnerNNZs array is redundant with \c OuterStarts because we the equality: \c InnerNNZs[j] = \c OuterStarts[j+1]-\c OuterStarts[j].
+Therefore, in practice a call to SparseMatrix::makeCompressed() frees this buffer.
+
+It is worth noting that most of our wrappers to external libraries requires compressed matrices as inputs.
+
+The results of %Eigen's operations always produces \b compressed sparse matrices.
+On the other hand, the insertion of a new element into a SparseMatrix converts this later to the \b uncompressed mode.
+
+Here is the previous matrix represented in compressed mode:
+<table class="manual">
+<tr><td>Values:</td>        <td>22</td><td>7</td><td>3</td><td>5</td><td>14</td><td>1</td><td>17</td><td>8</td></tr>
+<tr><td>InnerIndices:</td>  <td> 1</td><td>2</td><td>0</td><td>2</td><td> 4</td><td>2</td><td> 1</td><td>4</td></tr>
+</table>
+<table class="manual">
+<tr><td>OuterStarts:</td><td>0</td><td>2</td><td>4</td><td>5</td><td>6</td><td>\em 8 </td></tr>
+</table>
+
+A SparseVector is a special case of a SparseMatrix where only the \c Values and \c InnerIndices arrays are stored.
+There is no notion of compressed/uncompressed mode for a SparseVector.
+
+
+\section TutorialSparseExample First example
+
+Before describing each individual class, let's start with the following typical example: solving the Laplace equation \f$ \Delta u = 0 \f$ on a regular 2D grid using a finite difference scheme and Dirichlet boundary conditions.
+Such problem can be mathematically expressed as a linear problem of the form \f$ Ax=b \f$ where \f$ x \f$ is the vector of \c m unknowns (in our case, the values of the pixels), \f$ b \f$ is the right hand side vector resulting from the boundary conditions, and \f$ A \f$ is an \f$ m \times m \f$ matrix containing only a few non-zero elements resulting from the discretization of the Laplacian operator.
+
+<table class="manual">
+<tr><td>
+\include Tutorial_sparse_example.cpp
+</td>
+<td>
+\image html Tutorial_sparse_example.jpeg
+</td></tr></table>
+
+In this example, we start by defining a column-major sparse matrix type of double \c SparseMatrix<double>, and a triplet list of the same scalar type \c  Triplet<double>. A triplet is a simple object representing a non-zero entry as the triplet: \c row index, \c column index, \c value.
+
+In the main function, we declare a list \c coefficients of triplets (as a std vector) and the right hand side vector \f$ b \f$ which are filled by the \a buildProblem function.
+The raw and flat list of non-zero entries is then converted to a true SparseMatrix object \c A.
+Note that the elements of the list do not have to be sorted, and possible duplicate entries will be summed up.
+
+The last step consists of effectively solving the assembled problem.
+Since the resulting matrix \c A is symmetric by construction, we can perform a direct Cholesky factorization via the SimplicialLDLT class which behaves like its LDLT counterpart for dense objects.
+
+The resulting vector \c x contains the pixel values as a 1D array which is saved to a jpeg file shown on the right of the code above.
+
+Describing the \a buildProblem and \a save functions is out of the scope of this tutorial. They are given \ref TutorialSparse_example_details "here" for the curious and reproducibility purpose.
+
+
+
+
+\section TutorialSparseSparseMatrix The SparseMatrix class
+
+\b %Matrix \b and \b vector \b properties \n
+
+The SparseMatrix and SparseVector classes take three template arguments:
+ * the scalar type (e.g., double)
+ * the storage order (ColMajor or RowMajor, the default is ColMajor)
+ * the inner index type (default is \c int).
+
+As for dense Matrix objects, constructors takes the size of the object.
+Here are some examples:
+
+\code
+SparseMatrix<std::complex<float> > mat(1000,2000);         // declares a 1000x2000 column-major compressed sparse matrix of complex<float>
+SparseMatrix<double,RowMajor> mat(1000,2000);              // declares a 1000x2000 row-major compressed sparse matrix of double
+SparseVector<std::complex<float> > vec(1000);              // declares a column sparse vector of complex<float> of size 1000
+SparseVector<double,RowMajor> vec(1000);                   // declares a row sparse vector of double of size 1000
+\endcode
+
+In the rest of the tutorial, \c mat and \c vec represent any sparse-matrix and sparse-vector objects, respectively.
+
+The dimensions of a matrix can be queried using the following functions:
+<table class="manual">
+<tr><td>Standard \n dimensions</td><td>\code
+mat.rows()
+mat.cols()\endcode</td>
+<td>\code
+vec.size() \endcode</td>
+</tr>
+<tr><td>Sizes along the \n inner/outer dimensions</td><td>\code
+mat.innerSize()
+mat.outerSize()\endcode</td>
+<td></td>
+</tr>
+<tr><td>Number of non \n zero coefficients</td><td>\code
+mat.nonZeros() \endcode</td>
+<td>\code
+vec.nonZeros() \endcode</td></tr>
+</table>
+
+
+\b Iterating \b over \b the \b nonzero \b coefficients \n
+
+Random access to the elements of a sparse object can be done through the \c coeffRef(i,j) function.
+However, this function involves a quite expensive binary search.
+In most cases, one only wants to iterate over the non-zeros elements. This is achieved by a standard loop over the outer dimension, and then by iterating over the non-zeros of the current inner vector via an InnerIterator. Thus, the non-zero entries have to be visited in the same order than the storage order.
+Here is an example:
+<table class="manual">
+<tr><td>
+\code
+SparseMatrix<double> mat(rows,cols);
+for (int k=0; k<mat.outerSize(); ++k)
+  for (SparseMatrix<double>::InnerIterator it(mat,k); it; ++it)
+  {
+    it.value();
+    it.row();   // row index
+    it.col();   // col index (here it is equal to k)
+    it.index(); // inner index, here it is equal to it.row()
+  }
+\endcode
+</td><td>
+\code
+SparseVector<double> vec(size);
+for (SparseVector<double>::InnerIterator it(vec); it; ++it)
+{
+  it.value(); // == vec[ it.index() ]
+  it.index();
+}
+\endcode
+</td></tr>
+</table>
+For a writable expression, the referenced value can be modified using the valueRef() function.
+If the type of the sparse matrix or vector depends on a template parameter, then the \c typename keyword is
+required to indicate that \c InnerIterator denotes a type; see \ref TopicTemplateKeyword for details.
+
+
+\section TutorialSparseFilling Filling a sparse matrix
+
+Because of the special storage scheme of a SparseMatrix, special care has to be taken when adding new nonzero entries.
+For instance, the cost of a single purely random insertion into a SparseMatrix is \c O(nnz), where \c nnz is the current number of non-zero coefficients.
+
+The simplest way to create a sparse matrix while guaranteeing good performance is thus to first build a list of so-called \em triplets, and then convert it to a SparseMatrix.
+
+Here is a typical usage example:
+\code
+typedef Eigen::Triplet<double> T;
+std::vector<T> tripletList;
+tripletList.reserve(estimation_of_entries);
+for(...)
+{
+  // ...
+  tripletList.push_back(T(i,j,v_ij));
+}
+SparseMatrixType mat(rows,cols);
+mat.setFromTriplets(tripletList.begin(), tripletList.end());
+// mat is ready to go!
+\endcode
+The \c std::vector of triplets might contain the elements in arbitrary order, and might even contain duplicated elements that will be summed up by setFromTriplets().
+See the SparseMatrix::setFromTriplets() function and class Triplet for more details.
+
+
+In some cases, however, slightly higher performance, and lower memory consumption can be reached by directly inserting the non-zeros into the destination matrix.
+A typical scenario of this approach is illustrated bellow:
+\code
+1: SparseMatrix<double> mat(rows,cols);         // default is column major
+2: mat.reserve(VectorXi::Constant(cols,6));
+3: for each i,j such that v_ij != 0
+4:   mat.insert(i,j) = v_ij;                    // alternative: mat.coeffRef(i,j) += v_ij;
+5: mat.makeCompressed();                        // optional
+\endcode
+
+- The key ingredient here is the line 2 where we reserve room for 6 non-zeros per column. In many cases, the number of non-zeros per column or row can easily be known in advance. If it varies significantly for each inner vector, then it is possible to specify a reserve size for each inner vector by providing a vector object with an operator[](int j) returning the reserve size of the \c j-th inner vector (e.g., via a VectorXi or std::vector<int>). If only a rought estimate of the number of nonzeros per inner-vector can be obtained, it is highly recommended to overestimate it rather than the opposite. If this line is omitted, then the first insertion of a new element will reserve room for 2 elements per inner vector.
+- The line 4 performs a sorted insertion. In this example, the ideal case is when the \c j-th column is not full and contains non-zeros whose inner-indices are smaller than \c i. In this case, this operation boils down to trivial O(1) operation.
+- When calling insert(i,j) the element \c i \c ,j must not already exists, otherwise use the coeffRef(i,j) method that will allow to, e.g., accumulate values. This method first performs a binary search and finally calls insert(i,j) if the element does not already exist. It is more flexible than insert() but also more costly.
+- The line 5 suppresses the remaining empty space and transforms the matrix into a compressed column storage.
+
+
+
+\section TutorialSparseFeatureSet Supported operators and functions
+
+Because of their special storage format, sparse matrices cannot offer the same level of flexibility than dense matrices.
+In Eigen's sparse module we chose to expose only the subset of the dense matrix API which can be efficiently implemented.
+In the following \em sm denotes a sparse matrix, \em sv a sparse vector, \em dm a dense matrix, and \em dv a dense vector.
+
+\subsection TutorialSparse_BasicOps Basic operations
+
+%Sparse expressions support most of the unary and binary coefficient wise operations:
+\code
+sm1.real()   sm1.imag()   -sm1                    0.5*sm1
+sm1+sm2      sm1-sm2      sm1.cwiseProduct(sm2)
+\endcode
+However, <strong>a strong restriction is that the storage orders must match</strong>. For instance, in the following example:
+\code
+sm4 = sm1 + sm2 + sm3;
+\endcode
+sm1, sm2, and sm3 must all be row-major or all column-major.
+On the other hand, there is no restriction on the target matrix sm4.
+For instance, this means that for computing \f$ A^T + A \f$, the matrix \f$ A^T \f$ must be evaluated into a temporary matrix of compatible storage order:
+\code
+SparseMatrix<double> A, B;
+B = SparseMatrix<double>(A.transpose()) + A;
+\endcode
+
+Binary coefficient wise operators can also mix sparse and dense expressions:
+\code
+sm2 = sm1.cwiseProduct(dm1);
+dm2 = sm1 + dm1;
+dm2 = dm1 - sm1;
+\endcode
+Performance-wise, the adding/subtracting sparse and dense matrices is better performed in two steps. For instance, instead of doing <tt>dm2 = sm1 + dm1</tt>, better write:
+\code
+dm2 = dm1;
+dm2 += sm1;
+\endcode
+This version has the advantage to fully exploit the higher performance of dense storage (no indirection, SIMD, etc.), and to pay the cost of slow sparse evaluation on the few non-zeros of the sparse matrix only.
+
+
+%Sparse expressions also support transposition:
+\code
+sm1 = sm2.transpose();
+sm1 = sm2.adjoint();
+\endcode
+However, there is no transposeInPlace() method.
+
+
+\subsection TutorialSparse_Products Matrix products
+
+%Eigen supports various kind of sparse matrix products which are summarize below:
+  - \b sparse-dense:
+    \code
+dv2 = sm1 * dv1;
+dm2 = dm1 * sm1.adjoint();
+dm2 = 2. * sm1 * dm1;
+    \endcode
+  - \b symmetric \b sparse-dense. The product of a sparse symmetric matrix with a dense matrix (or vector) can also be optimized by specifying the symmetry with selfadjointView():
+    \code
+dm2 = sm1.selfadjointView<>() * dm1;        // if all coefficients of A are stored
+dm2 = A.selfadjointView<Upper>() * dm1;     // if only the upper part of A is stored
+dm2 = A.selfadjointView<Lower>() * dm1;     // if only the lower part of A is stored
+    \endcode
+  - \b sparse-sparse. For sparse-sparse products, two different algorithms are available. The default one is conservative and preserve the explicit zeros that might appear:
+    \code
+sm3 = sm1 * sm2;
+sm3 = 4 * sm1.adjoint() * sm2;
+    \endcode
+    The second algorithm prunes on the fly the explicit zeros, or the values smaller than a given threshold. It is enabled and controlled through the prune() functions:
+    \code
+sm3 = (sm1 * sm2).pruned();                  // removes numerical zeros
+sm3 = (sm1 * sm2).pruned(ref);               // removes elements much smaller than ref
+sm3 = (sm1 * sm2).pruned(ref,epsilon);       // removes elements smaller than ref*epsilon
+    \endcode
+
+  - \b permutations. Finally, permutations can be applied to sparse matrices too:
+    \code
+PermutationMatrix<Dynamic,Dynamic> P = ...;
+sm2 = P * sm1;
+sm2 = sm1 * P.inverse();
+sm2 = sm1.transpose() * P;
+    \endcode
+
+
+\subsection TutorialSparse_SubMatrices Block operations
+
+Regarding read-access, sparse matrices expose the same API than for dense matrices to access to sub-matrices such as blocks, columns, and rows. See \ref TutorialBlockOperations for a detailed introduction.
+However, for performance reasons, writing to a sub-sparse-matrix is much more limited, and currently only contiguous sets of columns (resp. rows) of a column-major (resp. row-major) SparseMatrix are writable. Moreover, this information has to be known at compile-time, leaving out methods such as <tt>block(...)</tt> and <tt>corner*(...)</tt>. The available API for write-access to a SparseMatrix are summarized below:
+\code
+SparseMatrix<double,ColMajor> sm1;
+sm1.col(j) = ...;
+sm1.leftCols(ncols) = ...;
+sm1.middleCols(j,ncols) = ...;
+sm1.rightCols(ncols) = ...;
+
+SparseMatrix<double,RowMajor> sm2;
+sm2.row(i) = ...;
+sm2.topRows(nrows) = ...;
+sm2.middleRows(i,nrows) = ...;
+sm2.bottomRows(nrows) = ...;
+\endcode
+
+In addition, sparse matrices expose the SparseMatrixBase::innerVector() and SparseMatrixBase::innerVectors() methods, which are aliases to the col/middleCols methods for a column-major storage, and to the row/middleRows methods for a row-major storage.
+
+\subsection TutorialSparse_TriangularSelfadjoint Triangular and selfadjoint views
+
+Just as with dense matrices, the triangularView() function can be used to address a triangular part of the matrix, and perform triangular solves with a dense right hand side:
+\code
+dm2 = sm1.triangularView<Lower>(dm1);
+dv2 = sm1.transpose().triangularView<Upper>(dv1);
+\endcode
+
+The selfadjointView() function permits various operations:
+ - optimized sparse-dense matrix products:
+    \code
+dm2 = sm1.selfadjointView<>() * dm1;        // if all coefficients of A are stored
+dm2 = A.selfadjointView<Upper>() * dm1;     // if only the upper part of A is stored
+dm2 = A.selfadjointView<Lower>() * dm1;     // if only the lower part of A is stored
+    \endcode
+ - copy of triangular parts:
+    \code
+sm2 = sm1.selfadjointView<Upper>();                               // makes a full selfadjoint matrix from the upper triangular part
+sm2.selfadjointView<Lower>() = sm1.selfadjointView<Upper>();      // copies the upper triangular part to the lower triangular part
+    \endcode
+ - application of symmetric permutations:
+ \code
+PermutationMatrix<Dynamic,Dynamic> P = ...;
+sm2 = A.selfadjointView<Upper>().twistedBy(P);                                // compute P S P' from the upper triangular part of A, and make it a full matrix
+sm2.selfadjointView<Lower>() = A.selfadjointView<Lower>().twistedBy(P);       // compute P S P' from the lower triangular part of A, and then only compute the lower part
+ \endcode
+
+Please, refer to the \link SparseQuickRefPage Quick Reference \endlink  guide for the list of supported operations. The list of linear solvers available is \link TopicSparseSystems here. \endlink

+/** \eigenManualPage TopicUnalignedArrayAssert Explanation of the assertion on unaligned arrays
+
+Hello! You are seeing this webpage because your program terminated on an assertion failure like this one:
+<pre>
+my_program: path/to/eigen/Eigen/src/Core/DenseStorage.h:44:
+Eigen::internal::matrix_array<T, Size, MatrixOptions, Align>::internal::matrix_array()
+[with T = double, int Size = 2, int MatrixOptions = 2, bool Align = true]:
+Assertion `(reinterpret_cast<size_t>(array) & (sizemask)) == 0 && "this assertion
+is explained here: http://eigen.tuxfamily.org/dox-devel/group__TopicUnalignedArrayAssert.html
+**** READ THIS WEB PAGE !!! ****"' failed.
+</pre>
+
+There are 4 known causes for this issue. Please read on to understand them and learn how to fix them.
+
+\eigenAutoToc
+
+\section where Where in my own code is the cause of the problem?
+
+First of all, you need to find out where in your own code this assertion was triggered from. At first glance, the error message doesn't look helpful, as it refers to a file inside Eigen! However, since your program crashed, if you can reproduce the crash, you can get a backtrace using any debugger. For example, if you're using GCC, you can use the GDB debugger as follows:
+\code
+$ gdb ./my_program          # Start GDB on your program
+> run                       # Start running your program
+...                         # Now reproduce the crash!
+> bt                        # Obtain the backtrace
+\endcode
+Now that you know precisely where in your own code the problem is happening, read on to understand what you need to change.
+
+\section c1 Cause 1: Structures having Eigen objects as members
+
+If you have code like this,
+
+\code
+class Foo
+{
+  //...
+  Eigen::Vector2d v;
+  //...
+};
+//...
+Foo *foo = new Foo;
+\endcode
+
+then you need to read this separate page: \ref TopicStructHavingEigenMembers "Structures Having Eigen Members".
+
+Note that here, Eigen::Vector2d is only used as an example, more generally the issue arises for all \ref TopicFixedSizeVectorizable "fixed-size vectorizable Eigen types".
+
+\section c2 Cause 2: STL Containers or manual memory allocation
+
+If you use STL Containers such as std::vector, std::map, ..., with %Eigen objects, or with classes containing %Eigen objects, like this,
+
+\code
+std::vector<Eigen::Matrix2f> my_vector;
+struct my_class { ... Eigen::Matrix2f m; ... };
+std::map<int, my_class> my_map;
+\endcode
+
+then you need to read this separate page: \ref TopicStlContainers "Using STL Containers with Eigen".
+
+Note that here, Eigen::Matrix2f is only used as an example, more generally the issue arises for all \ref TopicFixedSizeVectorizable "fixed-size vectorizable Eigen types" and \ref TopicStructHavingEigenMembers "structures having such Eigen objects as member".
+
+The same issue will be exhibited by any classes/functions by-passing operator new to allocate memory, that is, by performing custom memory allocation followed by calls to the placement new operator. This is for instance typically the case of \c std::make_shared or \c std::allocate_shared for which is the solution is to use an \ref aligned_allocator "aligned allocator" as detailed in the \ref TopicStlContainers "solution for STL containers".
+
+\section c3 Cause 3: Passing Eigen objects by value
+
+If some function in your code is getting an Eigen object passed by value, like this,
+
+\code
+void func(Eigen::Vector4d v);
+\endcode
+
+then you need to read this separate page: \ref TopicPassingByValue "Passing Eigen objects by value to functions".
+
+Note that here, Eigen::Vector4d is only used as an example, more generally the issue arises for all \ref TopicFixedSizeVectorizable "fixed-size vectorizable Eigen types".
+
+\section c4 Cause 4: Compiler making a wrong assumption on stack alignment (for instance GCC on Windows)
+
+This is a must-read for people using GCC on Windows (like MinGW or TDM-GCC). If you have this assertion failure in an innocent function declaring a local variable like this:
+
+\code
+void foo()
+{
+  Eigen::Quaternionf q;
+  //...
+}
+\endcode
+
+then you need to read this separate page: \ref TopicWrongStackAlignment "Compiler making a wrong assumption on stack alignment".
+
+Note that here, Eigen::Quaternionf is only used as an example, more generally the issue arises for all \ref TopicFixedSizeVectorizable "fixed-size vectorizable Eigen types".
+
+\section explanation General explanation of this assertion
+
+\ref TopicFixedSizeVectorizable "fixed-size vectorizable Eigen objects" must absolutely be created at 16-byte-aligned locations, otherwise SIMD instructions addressing them will crash.
+
+Eigen normally takes care of these alignment issues for you, by setting an alignment attribute on them and by overloading their "operator new".
+
+However there are a few corner cases where these alignment settings get overridden: they are the possible causes for this assertion.
+
+\section getrid I don't care about optimal vectorization, how do I get rid of that stuff?
+
+Three possibilities:
+<ul>
+  <li>Use the \c DontAlign option to Matrix, Array, Quaternion, etc. objects that gives you trouble. This way Eigen won't try to align them, and thus won"t assume any special alignment. On the down side, you will pay the cost of unaligned loads/stores for them, but on modern CPUs, the overhead is either null or marginal. See \link StructHavingEigenMembers_othersolutions here \endlink for an example.</li>
+  <li>Define \link TopicPreprocessorDirectivesPerformance EIGEN_DONT_ALIGN_STATICALLY \endlink. That disables all 16-byte (and above) static alignment code, while keeping 16-byte (or above) heap alignment. This has the effect of
+      vectorizing fixed-size objects (like Matrix4d) through unaligned stores (as controlled by \link TopicPreprocessorDirectivesPerformance EIGEN_UNALIGNED_VECTORIZE \endlink), while keeping unchanged the vectorization of dynamic-size objects
+      (like MatrixXd). But do note that this breaks ABI compatibility with the default behavior of static alignment.</li>
+  <li>Or define both \link TopicPreprocessorDirectivesPerformance  EIGEN_DONT_VECTORIZE \endlink and EIGEN_DISABLE_UNALIGNED_ARRAY_ASSERT. This keeps the
+      16-byte alignment code and thus preserves ABI compatibility, but completely disables vectorization.</li>
+</ul>
+
+If you want to know why defining EIGEN_DONT_VECTORIZE does not by itself disable 16-byte alignment and the assertion, here's the explanation:
+
+It doesn't disable the assertion, because otherwise code that runs fine without vectorization would suddenly crash when enabling vectorization.
+It doesn't disable 16-byte alignment, because that would mean that vectorized and non-vectorized code are not mutually ABI-compatible. This ABI compatibility is very important, even for people who develop only an in-house application, as for instance one may want to have in the same application a vectorized path and a non-vectorized path.

+For instance, one can use <a href="http://eigen.tuxfamily.org/Counter/redirect_to_mkl.php">Intel® MKL</a>, Apple's Accelerate framework on OSX, <a href="http://www.openblas.net/">OpenBLAS</a>, <a href="http://www.netlib.org/lapack">Netlib LAPACK</a>, etc.
+
+Do not miss this \link TopicUsingIntelMKL page \endlink for further discussions on the specific use of Intel® MKL (also includes VML, PARDISO, etc.)
+
+In order to use an external BLAS and/or LAPACK library, you must link you own application to the respective libraries and their dependencies.
+For LAPACK, you must also link to the standard <a href="http://www.netlib.org/lapack/lapacke.html">Lapacke</a> library, which is used as a convenient think layer between %Eigen's C++ code and LAPACK F77 interface. Then you must activate their usage by defining one or multiple of the following macros (\b before including any %Eigen's header):
+
+\note For Mac users, in order to use the lapack version shipped with the Accelerate framework, you also need the lapacke library.
+Using <a href="https://www.macports.org/">MacPorts</a>, this is as easy as:
+\code
+sudo port install lapack
+\endcode
+and then use the following link flags: \c -framework \c Accelerate \c /opt/local/lib/lapack/liblapacke.dylib

+
+When doing so, a number of %Eigen's algorithms are silently substituted with calls to BLAS or LAPACK routines.

+
+<!-- \section TopicUsingIntelMKL_Intro Eigen and Intel® Math Kernel Library (Intel® MKL) -->
+
+Since %Eigen version 3.1 and later, users can benefit from built-in Intel® Math Kernel Library (MKL) optimizations with an installed copy of Intel MKL 10.3 (or later).
+
+<a href="http://eigen.tuxfamily.org/Counter/redirect_to_mkl.php"> Intel MKL </a> provides highly optimized multi-threaded mathematical routines for x86-compatible architectures.
+Intel MKL is available on Linux, Mac and Windows for both Intel64 and IA32 architectures.
+
+\note
+Intel® MKL is a proprietary software and it is the responsibility of users to buy or register for community (free) Intel MKL licenses for their products. Moreover, the license of the user product has to allow linking to proprietary software that excludes any unmodified versions of the GPL.
+
+Using Intel MKL through %Eigen is easy:
+-# define the \c EIGEN_USE_MKL_ALL macro before including any %Eigen's header
+-# link your program to MKL libraries (see the <a href="http://software.intel.com/en-us/articles/intel-mkl-link-line-advisor/">MKL linking advisor</a>)
+-# on a 64bits system, you must use the LP64 interface (not the ILP64 one)
+
+When doing so, a number of %Eigen's algorithms are silently substituted with calls to Intel MKL routines.
+These substitutions apply only for \b Dynamic \b or \b large enough objects with one of the following four standard scalar types: \c float, \c double, \c complex<float>, and \c complex<double>.
+Operations on other scalar types or mixing reals and complexes will continue to use the built-in algorithms.
+
+In addition you can choose which parts will be substituted by defining one or multiple of the following macros:
+
+<table class="manual">
+<tr><td>\c EIGEN_USE_BLAS </td><td>Enables the use of external BLAS level 2 and 3 routines</td></tr>
+<tr class="alt"><td>\c EIGEN_USE_LAPACKE </td><td>Enables the use of external Lapack routines via the <a href="http://www.netlib.org/lapack/lapacke.html">Lapacke</a> C interface to Lapack</td></tr>
+<tr><td>\c EIGEN_USE_LAPACKE_STRICT </td><td>Same as \c EIGEN_USE_LAPACKE but algorithm of lower robustness are disabled. \n This currently concerns only JacobiSVD which otherwise would be replaced by \c gesvd that is less robust than Jacobi rotations.</td></tr>
+<tr class="alt"><td>\c EIGEN_USE_MKL_VML </td><td>Enables the use of Intel VML (vector operations)</td></tr>
+<tr><td>\c EIGEN_USE_MKL_ALL </td><td>Defines \c EIGEN_USE_BLAS, \c EIGEN_USE_LAPACKE, and \c EIGEN_USE_MKL_VML </td></tr>
+</table>
+
+The options can be combined with \b MKL_DIRECT_CALL to enable MKL direct call feature. This may help to increase performance of some MKL BLAS (?GEMM, ?GEMV, ?TRSM, ?AXPY and ?DOT) and LAPACK (LU, Cholesky and QR) routines for very small matrices. To make it work properly, the macro \c EIGEN_USE_MKL must also be defined in the case none of the other \c EIGEN_USE_MKL_* macros has been defined.
+
+Note that the BLAS and LAPACKE backends can be enabled for any F77 compatible BLAS and LAPACK libraries. See this \link TopicUsingBlasLapack page \endlink for the details.
+
+Finally, the PARDISO sparse solver shipped with Intel MKL can be used through the \ref PardisoLU, \ref PardisoLLT and \ref PardisoLDLT classes of the \ref PardisoSupport_Module.
+
+The following table summarizes the list of functions covered by \c EIGEN_USE_MKL_VML:
+<table class="manual">
+<tr><th>Code example</th><th>MKL routines</th></tr>
+<tr><td>\code
+v2=v1.array().sin();
+v2=v1.array().asin();
+v2=v1.array().cos();

+/** \page TopicCUDA Using Eigen in CUDA kernels
+
+\b Disclaimer: this page is about an \b experimental feature in %Eigen.
+
+Staring from CUDA 5.0, the CUDA compiler, \c nvcc, is able to properly parse %Eigen's code (almost).
+A few adaptations of the %Eigen's code already allows to use some parts of %Eigen in your own CUDA kernels.
+To this end you need the devel branch of %Eigen, CUDA 5.0 or greater with GCC.
+
+Known issues:
+
+ - \c nvcc with MS Visual Studio does not work (patch welcome)
+ 
+ - \c nvcc with \c clang does not work (patch welcome)
+ 
+ - \c nvcc 5.5 with gcc-4.7 (or greater) has issues with the standard \c \<limits\> header file. To workaround this, you can add the following before including any other files:
+   \code
+    // workaround issue between gcc >= 4.7 and cuda 5.5
+    #if (defined __GNUC__) && (__GNUC__>4 || __GNUC_MINOR__>=7)
+      #undef _GLIBCXX_ATOMIC_BUILTINS
+      #undef _GLIBCXX_USE_INT128
+    #endif
+   \endcode
+   
+ - On 64bits system Eigen uses \c long \c int as the default type for indexes and sizes. On CUDA device, it would make sense to default to 32 bits \c int.
+   However, to keep host and CUDA code compatible, this cannot be done automatically by %Eigen, and the user is thus required to define \c EIGEN_DEFAULT_DENSE_INDEX_TYPE to \c int throughout his code (or only for CUDA code if there is no interaction between host and CUDA code through %Eigen's object).

+/** \eigenManualPage TopicWrongStackAlignment Compiler making a wrong assumption on stack alignment
+
+<h4>It appears that this was a GCC bug that has been fixed in GCC 4.5.
+If you hit this issue, please upgrade to GCC 4.5 and report to us, so we can update this page.</h4>
+
+This is an issue that, so far, we met only with GCC on Windows: for instance, MinGW and TDM-GCC.
+
+By default, in a function like this,
+
+\code
+void foo()
+{
+  Eigen::Quaternionf q;
+  //...
+}
+\endcode
+
+GCC assumes that the stack is already 16-byte-aligned so that the object \a q will be created at a 16-byte-aligned location. For this reason, it doesn't take any special care to explicitly align the object \a q, as Eigen requires.
+
+The problem is that, in some particular cases, this assumption can be wrong on Windows, where the stack is only guaranteed to have 4-byte alignment. Indeed, even though GCC takes care of aligning the stack in the main function and does its best to keep it aligned, when a function is called from another thread or from a binary compiled with another compiler, the stack alignment can be corrupted. This results in the object 'q' being created at an unaligned location, making your program crash with the \ref TopicUnalignedArrayAssert "assertion on unaligned arrays". So far we found the three following solutions.
+
+
+\section sec_sol1 Local solution
+
+A local solution is to mark such a function with this attribute:
+\code
+__attribute__((force_align_arg_pointer)) void foo()
+{
+  Eigen::Quaternionf q;
+  //...
+}
+\endcode
+Read <a href="http://gcc.gnu.org/onlinedocs/gcc-4.4.0/gcc/Function-Attributes.html#Function-Attributes">this GCC documentation</a> to understand what this does. Of course this should only be done on GCC on Windows, so for portability you'll have to encapsulate this in a macro which you leave empty on other platforms. The advantage of this solution is that you can finely select which function might have a corrupted stack alignment. Of course on the downside this has to be done for every such function, so you may prefer one of the following two global solutions.
+
+
+\section sec_sol2 Global solutions
+
+A global solution is to edit your project so that when compiling with GCC on Windows, you pass this option to GCC:
+\code
+-mincoming-stack-boundary=2
+\endcode
+Explanation: this tells GCC that the stack is only required to be aligned to 2^2=4 bytes, so that GCC now knows that it really must take extra care to honor the 16 byte alignment of \ref TopicFixedSizeVectorizable "fixed-size vectorizable Eigen types" when needed.
+
+Another global solution is to pass this option to gcc:
+\code
+-mstackrealign
+\endcode
+which has the same effect than adding the \c force_align_arg_pointer attribute to all functions.
+
+These global solutions are easy to use, but note that they may slowdown your program because they lead to extra prologue/epilogue instructions for every function.

+# Eigen Tensors {#eigen_tensors}
+
+Tensors are multidimensional arrays of elements. Elements are typically scalars,
+but more complex types such as strings are also supported.
+
+[TOC]
+
+## Tensor Classes
+
+You can manipulate a tensor with one of the following classes.  They all are in
+the namespace `::Eigen.`
+
+
+### Class Tensor<data_type, rank>
+
+This is the class to use to create a tensor and allocate memory for it.  The
+class is templatized with the tensor datatype, such as float or int, and the
+tensor rank.  The rank is the number of dimensions, for example rank 2 is a
+matrix.
+
+Tensors of this class are resizable.  For example, if you assign a tensor of a
+different size to a Tensor, that tensor is resized to match its new value.
+
+#### Constructor `Tensor<data_type, rank>(size0, size1, ...)`
+
+Constructor for a Tensor.  The constructor must be passed `rank` integers
+indicating the sizes of the instance along each of the the `rank`
+dimensions.
+
+    // Create a tensor of rank 3 of sizes 2, 3, 4.  This tensor owns
+    // memory to hold 24 floating point values (24 = 2 x 3 x 4).
+    Tensor<float, 3> t_3d(2, 3, 4);
+
+    // Resize t_3d by assigning a tensor of different sizes, but same rank.
+    t_3d = Tensor<float, 3>(3, 4, 3);
+
+#### Constructor `Tensor<data_type, rank>(size_array)`
+
+Constructor where the sizes for the constructor are specified as an array of
+values instead of an explicitly list of parameters.  The array type to use is
+`Eigen::array<Eigen::Index>`.  The array can be constructed automatically
+from an initializer list.
+
+    // Create a tensor of strings of rank 2 with sizes 5, 7.
+    Tensor<string, 2> t_2d({5, 7});
+
+
+### Class `TensorFixedSize<data_type, Sizes<size0, size1, ...>>`
+
+Class to use for tensors of fixed size, where the size is known at compile
+time.  Fixed sized tensors can provide very fast computations because all their
+dimensions are known by the compiler.  FixedSize tensors are not resizable.
+
+If the total number of elements in a fixed size tensor is small enough the
+tensor data is held onto the stack and does not cause heap allocation and free.
+
+    // Create a 4 x 3 tensor of floats.
+    TensorFixedSize<float, Sizes<4, 3>> t_4x3;
+
+### Class `TensorMap<Tensor<data_type, rank>>`
+
+This is the class to use to create a tensor on top of memory allocated and
+owned by another part of your code.  It allows to view any piece of allocated
+memory as a Tensor.  Instances of this class do not own the memory where the
+data are stored.
+
+A TensorMap is not resizable because it does not own the memory where its data
+are stored.
+
+#### Constructor `TensorMap<Tensor<data_type, rank>>(data, size0, size1, ...)`
+
+Constructor for a Tensor.  The constructor must be passed a pointer to the
+storage for the data, and "rank" size attributes.  The storage has to be
+large enough to hold all the data.
+
+    // Map a tensor of ints on top of stack-allocated storage.
+    int storage[128];  // 2 x 4 x 2 x 8 = 128
+    TensorMap<Tensor<int, 4>> t_4d(storage, 2, 4, 2, 8);
+
+    // The same storage can be viewed as a different tensor.
+    // You can also pass the sizes as an array.
+    TensorMap<Tensor<int, 2>> t_2d(storage, 16, 8);
+
+    // You can also map fixed-size tensors.  Here we get a 1d view of
+    // the 2d fixed-size tensor.
+    TensorFixedSize<float, Sizes<4, 5>> t_4x3;
+    TensorMap<Tensor<float, 1>> t_12(t_4x3.data(), 12);
+
+
+#### Class `TensorRef`
+
+See Assigning to a TensorRef below.
+
+## Accessing Tensor Elements
+
+#### `<data_type> tensor(index0, index1...)`
+
+Return the element at position `(index0, index1...)` in tensor
+`tensor`.  You must pass as many parameters as the rank of `tensor`.
+The expression can be used as an l-value to set the value of the element at the
+specified position.  The value returned is of the datatype of the tensor.
+
+    // Set the value of the element at position (0, 1, 0);
+    Tensor<float, 3> t_3d(2, 3, 4);
+    t_3d(0, 1, 0) = 12.0f;
+
+    // Initialize all elements to random values.
+    for (int i = 0; i < 2; ++i) {
+      for (int j = 0; j < 3; ++j) {
+        for (int k = 0; k < 4; ++k) {
+          t_3d(i, j, k) = ...some random value...;
+        }
+      }
+    }
+
+    // Print elements of a tensor.
+    for (int i = 0; i < 2; ++i) {
+      LOG(INFO) << t_3d(i, 0, 0);
+    }
+
+
+## TensorLayout
+
+The tensor library supports 2 layouts: `ColMajor` (the default) and
+`RowMajor`.  Only the default column major layout is currently fully
+supported, and it is therefore not recommended to attempt to use the row major
+layout at the moment.
+
+The layout of a tensor is optionally specified as part of its type. If not
+specified explicitly column major is assumed.
+
+    Tensor<float, 3, ColMajor> col_major;  // equivalent to Tensor<float, 3>
+    TensorMap<Tensor<float, 3, RowMajor> > row_major(data, ...);
+
+All the arguments to an expression must use the same layout. Attempting to mix
+different layouts will result in a compilation error.
+
+It is possible to change the layout of a tensor or an expression using the
+`swap_layout()` method.  Note that this will also reverse the order of the
+dimensions.
+
+    Tensor<float, 2, ColMajor> col_major(2, 4);
+    Tensor<float, 2, RowMajor> row_major(2, 4);
+
+    Tensor<float, 2> col_major_result = col_major;  // ok, layouts match
+    Tensor<float, 2> col_major_result = row_major;  // will not compile
+
+    // Simple layout swap
+    col_major_result = row_major.swap_layout();
+    eigen_assert(col_major_result.dimension(0) == 4);
+    eigen_assert(col_major_result.dimension(1) == 2);
+
+    // Swap the layout and preserve the order of the dimensions
+    array<int, 2> shuffle(1, 0);
+    col_major_result = row_major.swap_layout().shuffle(shuffle);
+    eigen_assert(col_major_result.dimension(0) == 2);
+    eigen_assert(col_major_result.dimension(1) == 4);
+
+
+## Tensor Operations
+
+The Eigen Tensor library provides a vast library of operations on Tensors:
+numerical operations such as addition and multiplication, geometry operations
+such as slicing and shuffling, etc.  These operations are available as methods
+of the Tensor classes, and in some cases as operator overloads.  For example
+the following code computes the elementwise addition of two tensors:
+
+    Tensor<float, 3> t1(2, 3, 4);
+    ...set some values in t1...
+    Tensor<float, 3> t2(2, 3, 4);
+    ...set some values in t2...
+    // Set t3 to the element wise sum of t1 and t2
+    Tensor<float, 3> t3 = t1 + t2;
+
+While the code above looks easy enough, it is important to understand that the
+expression `t1 + t2` is not actually adding the values of the tensors.  The
+expression instead constructs a "tensor operator" object of the class
+TensorCwiseBinaryOp<scalar_sum>, which has references to the tensors
+`t1` and `t2`.  This is a small C++ object that knows how to add
+`t1` and `t2`.  It is only when the value of the expression is assigned
+to the tensor `t3` that the addition is actually performed.  Technically,
+this happens through the overloading of `operator=()` in the Tensor class.
+
+This mechanism for computing tensor expressions allows for lazy evaluation and
+optimizations which are what make the tensor library very fast.
+
+Of course, the tensor operators do nest, and the expression `t1 + t2 * 0.3f`
+is actually represented with the (approximate) tree of operators:
+
+    TensorCwiseBinaryOp<scalar_sum>(t1, TensorCwiseUnaryOp<scalar_mul>(t2, 0.3f))
+
+
+### Tensor Operations and C++ "auto"
+
+Because Tensor operations create tensor operators, the C++ `auto` keyword
+does not have its intuitive meaning.  Consider these 2 lines of code:
+
+    Tensor<float, 3> t3 = t1 + t2;
+    auto t4 = t1 + t2;
+
+In the first line we allocate the tensor `t3` and it will contain the
+result of the addition of `t1` and `t2`.  In the second line, `t4`
+is actually the tree of tensor operators that will compute the addition of
+`t1` and `t2`.  In fact, `t4` is *not* a tensor and you cannot get
+the values of its elements:
+
+    Tensor<float, 3> t3 = t1 + t2;
+    cout << t3(0, 0, 0);  // OK prints the value of t1(0, 0, 0) + t2(0, 0, 0)
+
+    auto t4 = t1 + t2;
+    cout << t4(0, 0, 0);  // Compilation error!
+
+When you use `auto` you do not get a Tensor as a result but instead a
+non-evaluated expression.  So only use `auto` to delay evaluation.
+
+Unfortunately, there is no single underlying concrete type for holding
+non-evaluated expressions, hence you have to use auto in the case when you do
+want to hold non-evaluated expressions.
+
+When you need the results of set of tensor computations you have to assign the
+result to a Tensor that will be capable of holding onto them.  This can be
+either a normal Tensor, a fixed size Tensor, or a TensorMap on an existing
+piece of memory.  All the following will work:
+
+    auto t4 = t1 + t2;
+
+    Tensor<float, 3> result = t4;  // Could also be: result(t4);
+    cout << result(0, 0, 0);
+
+    TensorMap<float, 4> result(<a float* with enough space>, <size0>, ...) = t4;
+    cout << result(0, 0, 0);
+
+    TensorFixedSize<float, Sizes<size0, ...>> result = t4;
+    cout << result(0, 0, 0);
+
+Until you need the results, you can keep the operation around, and even reuse
+it for additional operations.  As long as you keep the expression as an
+operation, no computation is performed.
+
+    // One way to compute exp((t1 + t2) * 0.2f);
+    auto t3 = t1 + t2;
+    auto t4 = t3 * 0.2f;
+    auto t5 = t4.exp();
+    Tensor<float, 3> result = t5;
+
+    // Another way, exactly as efficient as the previous one:
+    Tensor<float, 3> result = ((t1 + t2) * 0.2f).exp();
+
+### Controlling When Expression are Evaluated
+
+There are several ways to control when expressions are evaluated:
+
+*   Assignment to a Tensor, TensorFixedSize, or TensorMap.
+*   Use of the eval() method.
+*   Assignment to a TensorRef.
+
+#### Assigning to a Tensor, TensorFixedSize, or TensorMap.
+
+The most common way to evaluate an expression is to assign it to a Tensor.  In
+the example below, the `auto` declarations make the intermediate values
+"Operations", not Tensors, and do not cause the expressions to be evaluated.
+The assignment to the Tensor `result` causes the evaluation of all the
+operations.
+
+    auto t3 = t1 + t2;             // t3 is an Operation.
+    auto t4 = t3 * 0.2f;           // t4 is an Operation.
+    auto t5 = t4.exp();            // t5 is an Operation.
+    Tensor<float, 3> result = t5;  // The operations are evaluated.
+
+If you know the ranks and sizes of the Operation value you can assign the
+Operation to a TensorFixedSize instead of a Tensor, which is a bit more
+efficient.
+
+    // We know that the result is a 4x4x2 tensor!
+    TensorFixedSize<float, Sizes<4, 4, 2>> result = t5;
+
+Simiarly, assigning an expression to a TensorMap causes its evaluation.  Like
+tensors of type TensorFixedSize, TensorMaps cannot be resized so they have to
+have the rank and sizes of the expression that are assigned to them.
+
+#### Calling `eval()`.
+
+When you compute large composite expressions, you sometimes want to tell Eigen
+that an intermediate value in the expression tree is worth evaluating ahead of
+time.  This is done by inserting a call to the `eval()` method of the
+expression Operation.
+
+    // The previous example could have been written:
+    Tensor<float, 3> result = ((t1 + t2) * 0.2f).exp();
+
+    // If you want to compute (t1 + t2) once ahead of time you can write:
+    Tensor<float, 3> result = ((t1 + t2).eval() * 0.2f).exp();
+
+Semantically, calling `eval()` is equivalent to materializing the value of
+the expression in a temporary Tensor of the right size.  The code above in
+effect does:
+
+    // .eval() knows the size!
+    TensorFixedSize<float, Sizes<4, 4, 2>> tmp = t1 + t2;
+    Tensor<float, 3> result = (tmp * 0.2f).exp();
+
+Note that the return value of `eval()` is itself an Operation, so the
+following code does not do what you may think:
+
+    // Here t3 is an evaluation Operation.  t3 has not been evaluated yet.
+    auto t3 = (t1 + t2).eval();
+
+    // You can use t3 in another expression.  Still no evaluation.
+    auto t4 = (t3 * 0.2f).exp();
+
+    // The value is evaluated when you assign the Operation to a Tensor, using
+    // an intermediate tensor to represent t3.x
+    Tensor<float, 3> result = t4;
+
+While in the examples above calling `eval()` does not make a difference in
+performance, in other cases it can make a huge difference.  In the expression
+below the `broadcast()` expression causes the `X.maximum()` expression
+to be evaluated many times:
+
+    Tensor<...> X ...;
+    Tensor<...> Y = ((X - X.maximum(depth_dim).reshape(dims2d).broadcast(bcast))
+                     * beta).exp();
+
+Inserting a call to `eval()` between the `maximum()` and
+`reshape()` calls guarantees that maximum() is only computed once and
+greatly speeds-up execution:
+
+    Tensor<...> Y =
+      ((X - X.maximum(depth_dim).eval().reshape(dims2d).broadcast(bcast))
+        * beta).exp();
+
+In the other example below, the tensor `Y` is both used in the expression
+and its assignment.  This is an aliasing problem and if the evaluation is not
+done in the right order Y will be updated incrementally during the evaluation
+resulting in bogus results:
+
+     Tensor<...> Y ...;
+     Y = Y / (Y.sum(depth_dim).reshape(dims2d).broadcast(bcast));
+
+Inserting a call to `eval()` between the `sum()` and `reshape()`
+expressions ensures that the sum is computed before any updates to `Y` are
+done.
+
+     Y = Y / (Y.sum(depth_dim).eval().reshape(dims2d).broadcast(bcast));
+
+Note that an eval around the full right hand side expression is not needed
+because the generated has to compute the i-th value of the right hand side
+before assigning it to the left hand side.
+
+However, if you were assigning the expression value to a shuffle of `Y`
+then you would need to force an eval for correctness by adding an `eval()`
+call for the right hand side:
+
+     Y.shuffle(...) =
+        (Y / (Y.sum(depth_dim).eval().reshape(dims2d).broadcast(bcast))).eval();
+
+
+#### Assigning to a `TensorRef`.
+
+If you need to access only a few elements from the value of an expression you
+can avoid materializing the value in a full tensor by using a TensorRef.
+
+A TensorRef is a small wrapper class for any Eigen Operation.  It provides
+overloads for the `()` operator that let you access individual values in
+the expression.  TensorRef is convenient, because the Operation themselves do
+not provide a way to access individual elements.
+
+    // Create a TensorRef for the expression.  The expression is not
+    // evaluated yet.
+    TensorRef<Tensor<float, 3> > ref = ((t1 + t2) * 0.2f).exp();
+
+    // Use "ref" to access individual elements.  The expression is evaluated
+    // on the fly.
+    float at_0 = ref(0, 0, 0);
+    cout << ref(0, 1, 0);
+
+Only use TensorRef when you need a subset of the values of the expression.
+TensorRef only computes the values you access.  However note that if you are
+going to access all the values it will be much faster to materialize the
+results in a Tensor first.
+
+In some cases, if the full Tensor result would be very large, you may save
+memory by accessing it as a TensorRef.  But not always.  So don't count on it.
+
+
+### Controlling How Expressions Are Evaluated
+
+The tensor library provides several implementations of the various operations
+such as contractions and convolutions.  The implementations are optimized for
+different environments: single threaded on CPU, multi threaded on CPU, or on a
+GPU using cuda.  Additional implementations may be added later.
+
+You can choose which implementation to use with the `device()` call.  If
+you do not choose an implementation explicitly the default implementation that
+uses a single thread on the CPU is used.
+
+The default implementation has been optimized for recent Intel CPUs, taking
+advantage of SSE, AVX, and FMA instructions.  Work is ongoing to tune the
+library on ARM CPUs.  Note that you need to pass compiler-dependent flags
+to enable the use of SSE, AVX, and other instructions.
+
+For example, the following code adds two tensors using the default
+single-threaded CPU implementation:
+
+    Tensor<float, 2> a(30, 40);
+    Tensor<float, 2> b(30, 40);
+    Tensor<float, 2> c = a + b;
+
+To choose a different implementation you have to insert a `device()` call
+before the assignment of the result.  For technical C++ reasons this requires
+that the Tensor for the result be declared on its own.  This means that you
+have to know the size of the result.
+
+    Eigen::Tensor<float, 2> c(30, 40);
+    c.device(...) = a + b;
+
+The call to `device()` must be the last call on the left of the operator=.
+
+You must pass to the `device()` call an Eigen device object.  There are
+presently three devices you can use: DefaultDevice, ThreadPoolDevice and
+GpuDevice.
+
+
+#### Evaluating With the DefaultDevice
+
+This is exactly the same as not inserting a `device()` call.
+
+    DefaultDevice my_device;
+    c.device(my_device) = a + b;
+
+#### Evaluating with a Thread Pool
+
+    // Create the Eigen ThreadPoolDevice.
+    Eigen::ThreadPoolDevice my_device(4 /* number of threads to use */);
+
+    // Now just use the device when evaluating expressions.
+    Eigen::Tensor<float, 2> c(30, 50);
+    c.device(my_device) = a.contract(b, dot_product_dims);
+
+
+#### Evaluating On GPU
+
+This is presently a bit more complicated than just using a thread pool device.
+You need to create a GPU device but you also need to explicitly allocate the
+memory for tensors with cuda.
+
+
+## API Reference
+
+### Datatypes
+
+In the documentation of the tensor methods and Operation we mention datatypes
+that are tensor-type specific:
+
+#### `<Tensor-Type>::``Dimensions`
+
+Acts like an array of ints.  Has an `int size` attribute, and can be
+indexed like an array to access individual values.  Used to represent the
+dimensions of a tensor.  See `dimensions()`.
+
+#### `<Tensor-Type>::``Index`
+
+Acts like an `int`.  Used for indexing tensors along their dimensions.  See
+`operator()`, `dimension()`, and `size()`.
+
+#### `<Tensor-Type>::``Scalar`
+
+Represents the datatype of individual tensor elements.  For example, for a
+`Tensor<float>`, `Scalar` is the type `float`.  See
+`setConstant()`.
+
+#### `<Operation>`
+
+We use this pseudo type to indicate that a tensor Operation is returned by a
+method.  We indicate in the text the type and dimensions of the tensor that the
+Operation returns after evaluation.
+
+The Operation will have to be evaluated, for example by assigning it to a
+tensor, before you can access the values of the resulting tensor.  You can also
+access the values through a TensorRef.
+
+
+## Built-in Tensor Methods
+
+These are usual C++ methods that act on tensors immediately.  They are not
+Operations which provide delayed evaluation of their results.  Unless specified
+otherwise, all the methods listed below are available on all tensor classes:
+Tensor, TensorFixedSize, and TensorMap.
+
+## Metadata
+
+### `int NumDimensions`
+
+Constant value indicating the number of dimensions of a Tensor.  This is also
+known as the tensor "rank".
+
+      Eigen::Tensor<float, 2> a(3, 4);
+      cout << "Dims " << a.NumDimensions;
+      => Dims 2
+
+### `Dimensions dimensions()`
+
+Returns an array-like object representing the dimensions of the tensor.
+The actual type of the `dimensions()` result is `<Tensor-Type>::``Dimensions`.
+
+    Eigen::Tensor<float, 2> a(3, 4);
+    const Eigen::Tensor<float, 2>::Dimensions& d = a.dimensions();
+    cout << "Dim size: " << d.size << ", dim 0: " << d[0]
+         << ", dim 1: " << d[1];
+    => Dim size: 2, dim 0: 3, dim 1: 4
+
+If you use a C++11 compiler, you can use `auto` to simplify the code:
+
+    const auto& d = a.dimensions();
+    cout << "Dim size: " << d.size << ", dim 0: " << d[0]
+         << ", dim 1: " << d[1];
+    => Dim size: 2, dim 0: 3, dim 1: 4
+
+### `Index dimension(Index n)`
+
+Returns the n-th dimension of the tensor.  The actual type of the
+`dimension()` result is `<Tensor-Type>::``Index`, but you can
+always use it like an int.
+
+      Eigen::Tensor<float, 2> a(3, 4);
+      int dim1 = a.dimension(1);
+      cout << "Dim 1: " << dim1;
+      => Dim 1: 4
+
+### `Index size()`
+
+Returns the total number of elements in the tensor.  This is the product of all
+the tensor dimensions.  The actual type of the `size()` result is
+`<Tensor-Type>::``Index`, but you can always use it like an int.
+
+    Eigen::Tensor<float, 2> a(3, 4);
+    cout << "Size: " << a.size();
+    => Size: 12
+
+
+### Getting Dimensions From An Operation
+
+A few operations provide `dimensions()` directly,
+e.g. `TensorReslicingOp`.  Most operations defer calculating dimensions
+until the operation is being evaluated.  If you need access to the dimensions
+of a deferred operation, you can wrap it in a TensorRef (see Assigning to a
+TensorRef above), which provides `dimensions()` and `dimension()` as
+above.
+
+TensorRef can also wrap the plain Tensor types, so this is a useful idiom in
+templated contexts where the underlying object could be either a raw Tensor
+or some deferred operation (e.g. a slice of a Tensor).  In this case, the
+template code can wrap the object in a TensorRef and reason about its
+dimensionality while remaining agnostic to the underlying type.
+
+
+## Constructors
+
+### Tensor
+
+Creates a tensor of the specified size. The number of arguments must be equal
+to the rank of the tensor. The content of the tensor is not initialized.
+
+    Eigen::Tensor<float, 2> a(3, 4);
+    cout << "NumRows: " << a.dimension(0) << " NumCols: " << a.dimension(1) << endl;
+    => NumRows: 3 NumCols: 4
+
+### TensorFixedSize
+
+Creates a tensor of the specified size. The number of arguments in the Sizes<>
+template parameter determines the rank of the tensor. The content of the tensor
+is not initialized.
+
+    Eigen::TensorFixedSize<float, Sizes<3, 4>> a;
+    cout << "Rank: " << a.rank() << endl;
+    => Rank: 2
+    cout << "NumRows: " << a.dimension(0) << " NumCols: " << a.dimension(1) << endl;
+    => NumRows: 3 NumCols: 4
+
+### TensorMap
+
+Creates a tensor mapping an existing array of data. The data must not be freed
+until the TensorMap is discarded, and the size of the data must be large enough
+to accommodate the coefficients of the tensor.
+
+    float data[] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11};
+    Eigen::TensorMap<Tensor<float, 2>> a(data, 3, 4);
+    cout << "NumRows: " << a.dimension(0) << " NumCols: " << a.dimension(1) << endl;
+    => NumRows: 3 NumCols: 4
+    cout << "a(1, 2): " << a(1, 2) << endl;
+    => a(1, 2): 7
+
+
+## Contents Initialization
+
+When a new Tensor or a new TensorFixedSize are created, memory is allocated to
+hold all the tensor elements, but the memory is not initialized.  Similarly,
+when a new TensorMap is created on top of non-initialized memory the memory its
+contents are not initialized.
+
+You can use one of the methods below to initialize the tensor memory.  These
+have an immediate effect on the tensor and return the tensor itself as a
+result.  These are not tensor Operations which delay evaluation.
+
+### `<Tensor-Type> setConstant(const Scalar& val)`
+
+Sets all elements of the tensor to the constant value `val`.  `Scalar`
+is the type of data stored in the tensor.  You can pass any value that is
+convertible to that type.
+
+Returns the tensor itself in case you want to chain another call.
+
+    a.setConstant(12.3f);
+    cout << "Constant: " << endl << a << endl << endl;
+    =>
+    Constant:
+    12.3 12.3 12.3 12.3
+    12.3 12.3 12.3 12.3
+    12.3 12.3 12.3 12.3
+
+Note that `setConstant()` can be used on any tensor where the element type
+has a copy constructor and an `operator=()`:
+
+    Eigen::Tensor<string, 2> a(2, 3);
+    a.setConstant("yolo");
+    cout << "String tensor: " << endl << a << endl << endl;
+    =>
+    String tensor:
+    yolo yolo yolo
+    yolo yolo yolo
+
+
+### `<Tensor-Type> setZero()`
+
+Fills the tensor with zeros.  Equivalent to `setConstant(Scalar(0))`.
+Returns the tensor itself in case you want to chain another call.
+
+    a.setZero();
+    cout << "Zeros: " << endl << a << endl << endl;
+    =>
+    Zeros:
+    0 0 0 0
+    0 0 0 0
+    0 0 0 0
+
+
+### `<Tensor-Type> setValues({..initializer_list})`
+
+Fills the tensor with explicit values specified in a std::initializer_list.
+The type of the initializer list depends on the type and rank of the tensor.
+
+If the tensor has rank N, the initializer list must be nested N times.  The
+most deeply nested lists must contains P scalars of the Tensor type where P is
+the size of the last dimension of the Tensor.
+
+For example, for a `TensorFixedSize<float, 2, 3>` the initializer list must
+contains 2 lists of 3 floats each.
+
+`setValues()` returns the tensor itself in case you want to chain another
+call.
+
+    Eigen::Tensor<float, 2> a(2, 3);
+    a.setValues({{0.0f, 1.0f, 2.0f}, {3.0f, 4.0f, 5.0f}});
+    cout << "a" << endl << a << endl << endl;
+    =>
+    a
+    0 1 2
+    3 4 5
+
+If a list is too short, the corresponding elements of the tensor will not be
+changed.  This is valid at each level of nesting.  For example the following
+code only sets the values of the first row of the tensor.
+
+    Eigen::Tensor<int, 2> a(2, 3);
+    a.setConstant(1000);
+    a.setValues({{10, 20, 30}});
+    cout << "a" << endl << a << endl << endl;
+    =>
+    a
+    10   20   30
+    1000 1000 1000
+
+### `<Tensor-Type> setRandom()`
+
+Fills the tensor with random values.  Returns the tensor itself in case you
+want to chain another call.
+
+    a.setRandom();
+    cout << "Random: " << endl << a << endl << endl;
+    =>
+    Random:
+      0.680375    0.59688  -0.329554    0.10794
+     -0.211234   0.823295   0.536459 -0.0452059
+      0.566198  -0.604897  -0.444451   0.257742
+
+You can customize `setRandom()` by providing your own random number
+generator as a template argument:
+
+    a.setRandom<MyRandomGenerator>();
+
+Here, `MyRandomGenerator` must be a struct with the following member
+functions, where Scalar and Index are the same as `<Tensor-Type>::``Scalar`
+and `<Tensor-Type>::``Index`.
+
+See `struct UniformRandomGenerator` in TensorFunctors.h for an example.
+
+    // Custom number generator for use with setRandom().
+    struct MyRandomGenerator {
+      // Default and copy constructors. Both are needed
+      MyRandomGenerator() { }
+      MyRandomGenerator(const MyRandomGenerator& ) { }
+
+      // Return a random value to be used.  "element_location" is the
+      // location of the entry to set in the tensor, it can typically
+      // be ignored.
+      Scalar operator()(Eigen::DenseIndex element_location,
+                        Eigen::DenseIndex /*unused*/ = 0) const {
+        return <randomly generated value of type T>;
+      }
+
+      // Same as above but generates several numbers at a time.
+      typename internal::packet_traits<Scalar>::type packetOp(
+          Eigen::DenseIndex packet_location, Eigen::DenseIndex /*unused*/ = 0) const {
+        return <a packet of randomly generated values>;
+      }
+    };
+
+You can also use one of the 2 random number generators that are part of the
+tensor library:
+*   UniformRandomGenerator
+*   NormalRandomGenerator
+
+
+## Data Access
+
+The Tensor, TensorFixedSize, and TensorRef classes provide the following
+accessors to access the tensor coefficients:
+
+    const Scalar& operator()(const array<Index, NumIndices>& indices)
+    const Scalar& operator()(Index firstIndex, IndexTypes... otherIndices)
+    Scalar& operator()(const array<Index, NumIndices>& indices)
+    Scalar& operator()(Index firstIndex, IndexTypes... otherIndices)
+
+The number of indices must be equal to the rank of the tensor. Moreover, these
+accessors are not available on tensor expressions. In order to access the
+values of a tensor expression, the expression must either be evaluated or
+wrapped in a TensorRef.
+
+
+### `Scalar* data()` and `const Scalar* data() const`
+
+Returns a pointer to the storage for the tensor.  The pointer is const if the
+tensor was const.  This allows direct access to the data.  The layout of the
+data depends on the tensor layout: RowMajor or ColMajor.
+
+This access is usually only needed for special cases, for example when mixing
+Eigen Tensor code with other libraries.
+
+Scalar is the type of data stored in the tensor.
+
+    Eigen::Tensor<float, 2> a(3, 4);
+    float* a_data = a.data();
+    a_data[0] = 123.45f;
+    cout << "a(0, 0): " << a(0, 0);
+    => a(0, 0): 123.45
+
+
+## Tensor Operations
+
+All the methods documented below return non evaluated tensor `Operations`.
+These can be chained: you can apply another Tensor Operation to the value
+returned by the method.
+
+The chain of Operation is evaluated lazily, typically when it is assigned to a
+tensor.  See "Controlling when Expression are Evaluated" for more details about
+their evaluation.
+
+### `<Operation> constant(const Scalar& val)`
+
+Returns a tensor of the same type and dimensions as the original tensor but
+where all elements have the value `val`.
+
+This is useful, for example, when you want to add or subtract a constant from a
+tensor, or multiply every element of a tensor by a scalar.
+
+    Eigen::Tensor<float, 2> a(2, 3);
+    a.setConstant(1.0f);
+    Eigen::Tensor<float, 2> b = a + a.constant(2.0f);
+    Eigen::Tensor<float, 2> c = b * b.constant(0.2f);
+    cout << "a" << endl << a << endl << endl;
+    cout << "b" << endl << b << endl << endl;
+    cout << "c" << endl << c << endl << endl;
+    =>
+    a
+    1 1 1
+    1 1 1
+
+    b
+    3 3 3
+    3 3 3
+
+    c
+    0.6 0.6 0.6
+    0.6 0.6 0.6
+
+### `<Operation> random()`
+
+Returns a tensor of the same type and dimensions as the current tensor
+but where all elements have random values.
+
+This is for example useful to add random values to an existing tensor.
+The generation of random values can be customized in the same manner
+as for `setRandom()`.
+
+    Eigen::Tensor<float, 2> a(2, 3);
+    a.setConstant(1.0f);
+    Eigen::Tensor<float, 2> b = a + a.random();
+    cout << "a" << endl << a << endl << endl;
+    cout << "b" << endl << b << endl << endl;
+    =>
+    a
+    1 1 1
+    1 1 1
+
+    b

+## Unary Element Wise Operations
+
+All these operations take a single input tensor as argument and return a tensor
+of the same type and dimensions as the tensor to which they are applied.  The
+requested operations are applied to each element independently.
+
+### `<Operation> operator-()`
+
+Returns a tensor of the same type and dimensions as the original tensor
+containing the opposite values of the original tensor.
+
+    Eigen::Tensor<float, 2> a(2, 3);
+    a.setConstant(1.0f);
+    Eigen::Tensor<float, 2> b = -a;
+    cout << "a" << endl << a << endl << endl;
+    cout << "b" << endl << b << endl << endl;
+    =>
+    a
+    1 1 1
+    1 1 1
+
+    b
+    -1 -1 -1
+    -1 -1 -1
+
+### `<Operation> sqrt()`
+
+Returns a tensor of the same type and dimensions as the original tensor
+containing the square roots of the original tensor.
+
+### `<Operation> rsqrt()`
+
+Returns a tensor of the same type and dimensions as the original tensor
+containing the inverse square roots of the original tensor.
+
+### `<Operation> square()`
+
+Returns a tensor of the same type and dimensions as the original tensor
+containing the squares of the original tensor values.
+
+### `<Operation> inverse()`
+
+Returns a tensor of the same type and dimensions as the original tensor
+containing the inverse of the original tensor values.
+
+### `<Operation> exp()`
+
+Returns a tensor of the same type and dimensions as the original tensor
+containing the exponential of the original tensor.
+
+### `<Operation> log()`
+
+Returns a tensor of the same type and dimensions as the original tensor
+containing the natural logarithms of the original tensor.
+
+### `<Operation> abs()`
+
+Returns a tensor of the same type and dimensions as the original tensor
+containing the absolute values of the original tensor.
+
+### `<Operation> pow(Scalar exponent)`
+
+Returns a tensor of the same type and dimensions as the original tensor
+containing the coefficients of the original tensor to the power of the
+exponent.
+
+The type of the exponent, Scalar, is always the same as the type of the
+tensor coefficients.  For example, only integer exponents can be used in
+conjuntion with tensors of integer values.
+
+You can use cast() to lift this restriction.  For example this computes
+cubic roots of an int Tensor:
+
+    Eigen::Tensor<int, 2> a(2, 3);
+    a.setValues({{0, 1, 8}, {27, 64, 125}});
+    Eigen::Tensor<double, 2> b = a.cast<double>().pow(1.0 / 3.0);
+    cout << "a" << endl << a << endl << endl;
+    cout << "b" << endl << b << endl << endl;
+    =>
+    a
+    0   1   8
+    27  64 125
+
+    b
+    0 1 2
+    3 4 5
+
+### `<Operation>  operator * (Scalar scale)`
+
+Multiplies all the coefficients of the input tensor by the provided scale.
+
+### `<Operation>  cwiseMax(Scalar threshold)`
+TODO
+
+### `<Operation>  cwiseMin(Scalar threshold)`
+TODO
+
+### `<Operation>  unaryExpr(const CustomUnaryOp& func)`
+TODO
+
+
+## Binary Element Wise Operations
+
+These operations take two input tensors as arguments. The 2 input tensors should
+be of the same type and dimensions. The result is a tensor of the same
+dimensions as the tensors to which they are applied, and unless otherwise
+specified it is also of the same type. The requested operations are applied to
+each pair of elements independently.
+
+### `<Operation> operator+(const OtherDerived& other)`
+
+Returns a tensor of the same type and dimensions as the input tensors
+containing the coefficient wise sums of the inputs.
+
+### `<Operation> operator-(const OtherDerived& other)`
+
+Returns a tensor of the same type and dimensions as the input tensors
+containing the coefficient wise differences of the inputs.
+
+### `<Operation> operator*(const OtherDerived& other)`
+
+Returns a tensor of the same type and dimensions as the input tensors
+containing the coefficient wise products of the inputs.
+
+### `<Operation> operator/(const OtherDerived& other)`
+
+Returns a tensor of the same type and dimensions as the input tensors
+containing the coefficient wise quotients of the inputs.
+
+This operator is not supported for integer types.
+
+### `<Operation> cwiseMax(const OtherDerived& other)`
+
+Returns a tensor of the same type and dimensions as the input tensors
+containing the coefficient wise maximums of the inputs.
+
+### `<Operation> cwiseMin(const OtherDerived& other)`
+
+Returns a tensor of the same type and dimensions as the input tensors
+containing the coefficient wise mimimums of the inputs.
+
+### `<Operation> Logical operators`
+
+The following logical operators are supported as well:
+
+*   operator&&(const OtherDerived& other)
+*   operator||(const OtherDerived& other)
+*   operator<(const OtherDerived& other)
+*   operator<=(const OtherDerived& other)
+*   operator>(const OtherDerived& other)
+*   operator>=(const OtherDerived& other)
+*   operator==(const OtherDerived& other)
+*   operator!=(const OtherDerived& other)
+
+They all return a tensor of boolean values.
+
+
+## Selection (select(const ThenDerived& thenTensor, const ElseDerived& elseTensor)
+
+Selection is a coefficient-wise ternary operator that is the tensor equivalent
+to the if-then-else operation.
+
+    Tensor<bool, 3> if = ...;
+    Tensor<float, 3> then = ...;
+    Tensor<float, 3> else = ...;
+    Tensor<float, 3> result = if.select(then, else);
+
+The 3 arguments must be of the same dimensions, which will also be the dimension
+of the result.  The 'if' tensor must be of type boolean, the 'then' and the
+'else' tensor must be of the same type, which will also be the type of the
+result.
+
+Each coefficient in the result is equal to the corresponding coefficient in the
+'then' tensor if the corresponding value in the 'if' tensor is true. If not, the
+resulting coefficient will come from the 'else' tensor.
+
+
+## Contraction
+
+Tensor *contractions* are a generalization of the matrix product to the
+multidimensional case.
+
+    // Create 2 matrices using tensors of rank 2
+    Eigen::Tensor<int, 2> a(2, 3);
+    a.setValues({{1, 2, 3}, {6, 5, 4}});
+    Eigen::Tensor<int, 2> b(3, 2);
+    b.setValues({{1, 2}, {4, 5}, {5, 6}});
+
+    // Compute the traditional matrix product
+    Eigen::array<Eigen::IndexPair<int>, 1> product_dims = { Eigen::IndexPair<int>(1, 0) };
+    Eigen::Tensor<int, 2> AB = a.contract(b, product_dims);
+
+    // Compute the product of the transpose of the matrices
+    Eigen::array<Eigen::IndexPair<int>, 1> transposed_product_dims = { Eigen::IndexPair<int>(0, 1) };
+    Eigen::Tensor<int, 2> AtBt = a.contract(b, transposed_product_dims);
+
+    // Contraction to scalar value using a double contraction.
+    // First coordinate of both tensors are contracted as well as both second coordinates, i.e., this computes the sum of the squares of the elements.
+    Eigen::array<Eigen::IndexPair<int>, 2> double_contraction_product_dims = { Eigen::IndexPair<int>(0, 0), Eigen::IndexPair<int>(1, 1) };
+    Eigen::Tensor<int, 0> AdoubleContractedA = a.contract(a, double_contraction_product_dims);
+
+    // Extracting the scalar value of the tensor contraction for further usage
+    int value = AdoubleContractedA(0);
+
+## Reduction Operations
+
+A *Reduction* operation returns a tensor with fewer dimensions than the
+original tensor.  The values in the returned tensor are computed by applying a
+*reduction operator* to slices of values from the original tensor.  You specify
+the dimensions along which the slices are made.
+
+The Eigen Tensor library provides a set of predefined reduction operators such
+as `maximum()` and `sum()` and lets you define additional operators by
+implementing a few methods from a reductor template.
+
+### Reduction Dimensions
+
+All reduction operations take a single parameter of type
+`<TensorType>::``Dimensions` which can always be specified as an array of
+ints.  These are called the "reduction dimensions."  The values are the indices
+of the dimensions of the input tensor over which the reduction is done.  The
+parameter can have at most as many element as the rank of the input tensor;
+each element must be less than the tensor rank, as it indicates one of the
+dimensions to reduce.
+
+Each dimension of the input tensor should occur at most once in the reduction
+dimensions as the implementation does not remove duplicates.
+
+The order of the values in the reduction dimensions does not affect the
+results, but the code may execute faster if you list the dimensions in
+increasing order.
+
+Example: Reduction along one dimension.
+
+    // Create a tensor of 2 dimensions
+    Eigen::Tensor<int, 2> a(2, 3);
+    a.setValues({{1, 2, 3}, {6, 5, 4}});
+    // Reduce it along the second dimension (1)...
+    Eigen::array<int, 1> dims({1 /* dimension to reduce */});
+    // ...using the "maximum" operator.
+    // The result is a tensor with one dimension.  The size of
+    // that dimension is the same as the first (non-reduced) dimension of a.
+    Eigen::Tensor<int, 1> b = a.maximum(dims);
+    cout << "a" << endl << a << endl << endl;
+    cout << "b" << endl << b << endl << endl;
+    =>
+    a
+    1 2 3
+    6 5 4
+
+    b
+    3
+    6
+
+Example: Reduction along two dimensions.
+
+    Eigen::Tensor<float, 3, Eigen::ColMajor> a(2, 3, 4);
+    a.setValues({{{0.0f, 1.0f, 2.0f, 3.0f},
+                  {7.0f, 6.0f, 5.0f, 4.0f},
+                  {8.0f, 9.0f, 10.0f, 11.0f}},
+                 {{12.0f, 13.0f, 14.0f, 15.0f},
+                  {19.0f, 18.0f, 17.0f, 16.0f},
+                  {20.0f, 21.0f, 22.0f, 23.0f}}});
+    // The tensor a has 3 dimensions.  We reduce along the
+    // first 2, resulting in a tensor with a single dimension
+    // of size 4 (the last dimension of a.)
+    // Note that we pass the array of reduction dimensions
+    // directly to the maximum() call.
+    Eigen::Tensor<float, 1, Eigen::ColMajor> b =
+        a.maximum(Eigen::array<int, 2>({0, 1}));
+    cout << "b" << endl << b << endl << endl;
+    =>
+    b
+    20
+    21
+    22
+    23
+
+#### Reduction along all dimensions
+
+As a special case, if you pass no parameter to a reduction operation the
+original tensor is reduced along *all* its dimensions.  The result is a
+scalar, represented as a zero-dimension tensor.
+
+    Eigen::Tensor<float, 3> a(2, 3, 4);
+    a.setValues({{{0.0f, 1.0f, 2.0f, 3.0f},
+                  {7.0f, 6.0f, 5.0f, 4.0f},
+                  {8.0f, 9.0f, 10.0f, 11.0f}},
+                 {{12.0f, 13.0f, 14.0f, 15.0f},
+                  {19.0f, 18.0f, 17.0f, 16.0f},
+                  {20.0f, 21.0f, 22.0f, 23.0f}}});
+    // Reduce along all dimensions using the sum() operator.
+    Eigen::Tensor<float, 0> b = a.sum();
+    cout << "b" << endl << b << endl << endl;
+    =>
+    b
+    276
+
+
+### `<Operation> sum(const Dimensions& new_dims)`
+### `<Operation> sum()`
+
+Reduce a tensor using the sum() operator.  The resulting values
+are the sum of the reduced values.
+
+### `<Operation> mean(const Dimensions& new_dims)`
+### `<Operation> mean()`
+
+Reduce a tensor using the mean() operator.  The resulting values
+are the mean of the reduced values.
+
+### `<Operation> maximum(const Dimensions& new_dims)`
+### `<Operation> maximum()`
+
+Reduce a tensor using the maximum() operator.  The resulting values are the
+largest of the reduced values.
+
+### `<Operation> minimum(const Dimensions& new_dims)`

+### `<Operation> any()`
+Reduce a tensor using the any() operator.  Casts tensor to bool and then checks

+
+Reduce a tensor using a user-defined reduction operator.  See `SumReducer`
+in TensorFunctors.h for information on how to implement a reduction operator.
+
+
+## Scan Operations
+
+A *Scan* operation returns a tensor with the same dimensions as the original
+tensor. The operation performs an inclusive scan along the specified
+axis, which means it computes a running total along the axis for a given
+reduction operation.
+If the reduction operation corresponds to summation, then this computes the
+prefix sum of the tensor along the given axis.
+
+Example:
+dd a comment to this line
+
+    // Create a tensor of 2 dimensions
+    Eigen::Tensor<int, 2> a(2, 3);
+    a.setValues({{1, 2, 3}, {4, 5, 6}});
+    // Scan it along the second dimension (1) using summation
+    Eigen::Tensor<int, 2> b = a.cumsum(1);
+    // The result is a tensor with the same size as the input
+    cout << "a" << endl << a << endl << endl;
+    cout << "b" << endl << b << endl << endl;
+    =>
+    a
+    1 2 3
+    4 5 6
+
+    b
+    1  3  6
+    4  9 15
+
+### `<Operation> cumsum(const Index& axis)`
+
+Perform a scan by summing consecutive entries.
+
+### `<Operation> cumprod(const Index& axis)`
+
+Perform a scan by multiplying consecutive entries.
+
+
+## Convolutions
+
+### `<Operation> convolve(const Kernel& kernel, const Dimensions& dims)`
+
+Returns a tensor that is the output of the convolution of the input tensor with the kernel,
+along the specified dimensions of the input tensor. The dimension size for dimensions of the output tensor
+which were part of the convolution will be reduced by the formula:
+output_dim_size = input_dim_size - kernel_dim_size + 1 (requires: input_dim_size >= kernel_dim_size).
+The dimension sizes for dimensions that were not part of the convolution will remain the same.
+Performance of the convolution can depend on the length of the stride(s) of the input tensor dimension(s) along which the
+convolution is computed (the first dimension has the shortest stride for ColMajor, whereas RowMajor's shortest stride is
+for the last dimension).
+
+    // Compute convolution along the second and third dimension.
+    Tensor<float, 4, DataLayout> input(3, 3, 7, 11);
+    Tensor<float, 2, DataLayout> kernel(2, 2);
+    Tensor<float, 4, DataLayout> output(3, 2, 6, 11);
+    input.setRandom();
+    kernel.setRandom();
+
+    Eigen::array<ptrdiff_t, 2> dims({1, 2});  // Specify second and third dimension for convolution.
+    output = input.convolve(kernel, dims);
+
+    for (int i = 0; i < 3; ++i) {
+      for (int j = 0; j < 2; ++j) {
+        for (int k = 0; k < 6; ++k) {
+          for (int l = 0; l < 11; ++l) {
+            const float result = output(i,j,k,l);
+            const float expected = input(i,j+0,k+0,l) * kernel(0,0) +
+                                   input(i,j+1,k+0,l) * kernel(1,0) +
+                                   input(i,j+0,k+1,l) * kernel(0,1) +
+                                   input(i,j+1,k+1,l) * kernel(1,1);
+            VERIFY_IS_APPROX(result, expected);
+          }
+        }
+      }
+    }
+
+
+## Geometrical Operations
+
+These operations return a Tensor with different dimensions than the original
+Tensor.  They can be used to access slices of tensors, see them with different
+dimensions, or pad tensors with additional data.
+
+### `<Operation> reshape(const Dimensions& new_dims)`
+
+Returns a view of the input tensor that has been reshaped to the specified
+new dimensions.  The argument new_dims is an array of Index values.  The
+rank of the resulting tensor is equal to the number of elements in new_dims.
+
+The product of all the sizes in the new dimension array must be equal to
+the number of elements in the input tensor.
+
+    // Increase the rank of the input tensor by introducing a new dimension
+    // of size 1.
+    Tensor<float, 2> input(7, 11);
+    array<int, 3> three_dims{{7, 11, 1}};
+    Tensor<float, 3> result = input.reshape(three_dims);
+
+    // Decrease the rank of the input tensor by merging 2 dimensions;
+    array<int, 1> one_dim{{7 * 11}};
+    Tensor<float, 1> result = input.reshape(one_dim);
+
+This operation does not move any data in the input tensor, so the resulting
+contents of a reshaped Tensor depend on the data layout of the original Tensor.
+
+For example this is what happens when you `reshape()` a 2D ColMajor tensor
+to one dimension:
+
+    Eigen::Tensor<float, 2, Eigen::ColMajor> a(2, 3);
+    a.setValues({{0.0f, 100.0f, 200.0f}, {300.0f, 400.0f, 500.0f}});
+    Eigen::array<Eigen::DenseIndex, 1> one_dim({3 * 2});
+    Eigen::Tensor<float, 1, Eigen::ColMajor> b = a.reshape(one_dim);
+    cout << "b" << endl << b << endl;
+    =>
+    b
+      0
+    300
+    100
+    400
+    200
+    500
+
+This is what happens when the 2D Tensor is RowMajor:
+
+    Eigen::Tensor<float, 2, Eigen::RowMajor> a(2, 3);
+    a.setValues({{0.0f, 100.0f, 200.0f}, {300.0f, 400.0f, 500.0f}});
+    Eigen::array<Eigen::DenseIndex, 1> one_dim({3 * 2});
+    Eigen::Tensor<float, 1, Eigen::RowMajor> b = a.reshape(one_dim);
+    cout << "b" << endl << b << endl;
+    =>
+    b
+      0
+    100
+    200
+    300
+    400
+    500
+
+The reshape operation is a lvalue. In other words, it can be used on the left
+side of the assignment operator.
+
+The previous example can be rewritten as follow:
+
+    Eigen::Tensor<float, 2, Eigen::ColMajor> a(2, 3);
+    a.setValues({{0.0f, 100.0f, 200.0f}, {300.0f, 400.0f, 500.0f}});
+    Eigen::array<Eigen::DenseIndex, 2> two_dim({2, 3});
+    Eigen::Tensor<float, 1, Eigen::ColMajor> b(6);
+    b.reshape(two_dim) = a;
+    cout << "b" << endl << b << endl;
+    =>
+    b
+      0
+    300
+    100
+    400
+    200
+    500
+
+Note that "b" itself was not reshaped but that instead the assignment is done to
+the reshape view of b.
+
+
+### `<Operation> shuffle(const Shuffle& shuffle)`
+
+Returns a copy of the input tensor whose dimensions have been
+reordered according to the specified permutation. The argument shuffle
+is an array of Index values. Its size is the rank of the input
+tensor. It must contain a permutation of 0, 1, ..., rank - 1. The i-th
+dimension of the output tensor equals to the size of the shuffle[i]-th
+dimension of the input tensor. For example:
+
+    // Shuffle all dimensions to the left by 1.
+    Tensor<float, 3> input(20, 30, 50);
+    // ... set some values in input.
+    Tensor<float, 3> output = input.shuffle({1, 2, 0})
+
+    eigen_assert(output.dimension(0) == 30);
+    eigen_assert(output.dimension(1) == 50);
+    eigen_assert(output.dimension(2) == 20);
+
+Indices into the output tensor are shuffled accordingly to formulate
+indices into the input tensor. For example, one can assert in the above
+code snippet that:
+
+    eigen_assert(output(3, 7, 11) == input(11, 3, 7));
+
+In general, one can assert that
+
+    eigen_assert(output(..., indices[shuffle[i]], ...) ==
+                 input(..., indices[i], ...))
+
+The shuffle operation results in a lvalue, which means that it can be assigned
+to. In other words, it can be used on the left side of the assignment operator.
+
+Let's rewrite the previous example to take advantage of this feature:
+
+    // Shuffle all dimensions to the left by 1.
+    Tensor<float, 3> input(20, 30, 50);
+    // ... set some values in input.
+    Tensor<float, 3> output(30, 50, 20);
+    output.shuffle({2, 0, 1}) = input;
+
+
+### `<Operation> stride(const Strides& strides)`
+
+Returns a view of the input tensor that strides (skips stride-1
+elements) along each of the dimensions.  The argument strides is an
+array of Index values.  The dimensions of the resulting tensor are
+ceil(input_dimensions[i] / strides[i]).
+
+For example this is what happens when you `stride()` a 2D tensor:
+
+    Eigen::Tensor<int, 2> a(4, 3);
+    a.setValues({{0, 100, 200}, {300, 400, 500}, {600, 700, 800}, {900, 1000, 1100}});
+    Eigen::array<Eigen::DenseIndex, 2> strides({3, 2});
+    Eigen::Tensor<int, 2> b = a.stride(strides);
+    cout << "b" << endl << b << endl;
+    =>
+    b
+       0   200
+     900  1100
+
+It is possible to assign a tensor to a stride:
+    Tensor<float, 3> input(20, 30, 50);
+    // ... set some values in input.
+    Tensor<float, 3> output(40, 90, 200);
+    output.stride({2, 3, 4}) = input;
+
+
+### `<Operation> slice(const StartIndices& offsets, const Sizes& extents)`
+
+Returns a sub-tensor of the given tensor. For each dimension i, the slice is
+made of the coefficients stored between offset[i] and offset[i] + extents[i] in
+the input tensor.

+
+
+### `<Operation> chip(const Index offset, const Index dim)`
+
+A chip is a special kind of slice. It is the subtensor at the given offset in
+the dimension dim. The returned tensor has one fewer dimension than the input
+tensor: the dimension dim is removed.
+
+For example, a matrix chip would be either a row or a column of the input
+matrix.
+
+    Eigen::Tensor<int, 2> a(4, 3);
+    a.setValues({{0, 100, 200}, {300, 400, 500},
+                 {600, 700, 800}, {900, 1000, 1100}});
+    Eigen::Tensor<int, 1> row_3 = a.chip(2, 0);
+    Eigen::Tensor<int, 1> col_2 = a.chip(1, 1);
+    cout << "a" << endl << a << endl;
+    =>
+    a
+       0   100   200
+     300   400   500
+     600   700   800
+     900  1000  1100
+    cout << "row_3" << endl << row_3 << endl;
+    =>
+    row_3
+       600   700   800
+    cout << "col_2" << endl << col_2 << endl;
+    =>
+    col_2
+       100   400   700    1000
+
+It is possible to assign values to a tensor chip since the chip operation is a
+lvalue. For example:
+
+    Eigen::Tensor<int, 1> a(3);
+    a.setValues({{100, 200, 300}});
+    Eigen::Tensor<int, 2> b(2, 3);
+    b.setZero();
+    b.chip(0, 0) = a;
+    cout << "a" << endl << a << endl;
+    =>
+    a
+     100
+     200
+     300
+    cout << "b" << endl << b << endl;
+    =>
+    b
+       100   200   300
+         0     0     0
+
+
+### `<Operation> reverse(const ReverseDimensions& reverse)`
+
+Returns a view of the input tensor that reverses the order of the coefficients
+along a subset of the dimensions.  The argument reverse is an array of boolean
+values that indicates whether or not the order of the coefficients should be
+reversed along each of the dimensions.  This operation preserves the dimensions
+of the input tensor.
+
+For example this is what happens when you `reverse()` the first dimension
+of a 2D tensor:
+
+    Eigen::Tensor<int, 2> a(4, 3);
+    a.setValues({{0, 100, 200}, {300, 400, 500},
+                {600, 700, 800}, {900, 1000, 1100}});
+    Eigen::array<bool, 2> reverse({true, false});
+    Eigen::Tensor<int, 2> b = a.reverse(reverse);
+    cout << "a" << endl << a << endl << "b" << endl << b << endl;
+    =>
+    a
+       0   100   200
+     300   400   500
+     600   700   800
+     900  1000  1100
+    b
+     900  1000  1100
+     600   700   800
+     300   400   500
+       0   100   200
+
+
+### `<Operation> broadcast(const Broadcast& broadcast)`
+
+Returns a view of the input tensor in which the input is replicated one to many
+times.
+The broadcast argument specifies how many copies of the input tensor need to be
+made in each of the dimensions.
+
+    Eigen::Tensor<int, 2> a(2, 3);
+    a.setValues({{0, 100, 200}, {300, 400, 500}});
+    Eigen::array<int, 2> bcast({3, 2});
+    Eigen::Tensor<int, 2> b = a.broadcast(bcast);
+    cout << "a" << endl << a << endl << "b" << endl << b << endl;
+    =>
+    a
+       0   100   200
+     300   400   500
+    b
+       0   100   200    0   100   200

+     300   400   500  300   400   500
+
+### `<Operation> concatenate(const OtherDerived& other, Axis axis)`
+
+TODO
+
+### `<Operation>  pad(const PaddingDimensions& padding)`
+
+Returns a view of the input tensor in which the input is padded with zeros.
+
+    Eigen::Tensor<int, 2> a(2, 3);
+    a.setValues({{0, 100, 200}, {300, 400, 500}});
+    Eigen::array<pair<int, int>, 2> paddings;
+    paddings[0] = make_pair(0, 1);
+    paddings[1] = make_pair(2, 3);
+    Eigen::Tensor<int, 2> b = a.pad(paddings);
+    cout << "a" << endl << a << endl << "b" << endl << b << endl;
+    =>
+    a

+
+
+### `<Operation>  extract_patches(const PatchDims& patch_dims)`
+
+Returns a tensor of coefficient patches extracted from the input tensor, where
+each patch is of dimension specified by 'patch_dims'. The returned tensor has
+one greater dimension than the input tensor, which is used to index each patch.
+The patch index in the output tensor depends on the data layout of the input
+tensor: the patch index is the last dimension ColMajor layout, and the first
+dimension in RowMajor layout.
+
+For example, given the following input tensor:
+
+  Eigen::Tensor<float, 2, DataLayout> tensor(3,4);
+  tensor.setValues({{0.0f, 1.0f, 2.0f, 3.0f},
+                    {4.0f, 5.0f, 6.0f, 7.0f},
+                    {8.0f, 9.0f, 10.0f, 11.0f}});
+
+  cout << "tensor: " << endl << tensor << endl;
+=>
+tensor:
+ 0   1   2   3
+ 4   5   6   7
+ 8   9  10  11
+
+Six 2x2 patches can be extracted and indexed using the following code:
+
+  Eigen::Tensor<float, 3, DataLayout> patch;
+  Eigen::array<ptrdiff_t, 2> patch_dims;
+  patch_dims[0] = 2;
+  patch_dims[1] = 2;
+  patch = tensor.extract_patches(patch_dims);
+  for (int k = 0; k < 6; ++k) {
+    cout << "patch index: " << k << endl;
+    for (int i = 0; i < 2; ++i) {
+      for (int j = 0; j < 2; ++j) {
+        if (DataLayout == ColMajor) {
+          cout << patch(i, j, k) << " ";
+        } else {
+          cout << patch(k, i, j) << " ";
+        }
+      }
+      cout << endl;
+    }
+  }
+
+This code results in the following output when the data layout is ColMajor:
+
+patch index: 0
+0 1
+4 5
+patch index: 1
+4 5
+8 9
+patch index: 2
+1 2
+5 6
+patch index: 3
+5 6
+9 10
+patch index: 4
+2 3
+6 7
+patch index: 5
+6 7
+10 11
+
+This code results in the following output when the data layout is RowMajor:
+(NOTE: the set of patches is the same as in ColMajor, but are indexed differently).
+
+patch index: 0
+0 1
+4 5
+patch index: 1
+1 2
+5 6
+patch index: 2
+2 3
+6 7
+patch index: 3
+4 5
+8 9
+patch index: 4
+5 6
+9 10
+patch index: 5
+6 7
+10 11
+
+### `<Operation>  extract_image_patches(const Index patch_rows, const Index patch_cols, const Index row_stride, const Index col_stride, const PaddingType padding_type)`
+
+Returns a tensor of coefficient image patches extracted from the input tensor,
+which is expected to have dimensions ordered as follows (depending on the data
+layout of the input tensor, and the number of additional dimensions 'N'):
+
+*) ColMajor
+1st dimension: channels (of size d)
+2nd dimension: rows (of size r)
+3rd dimension: columns (of size c)
+4th-Nth dimension: time (for video) or batch (for bulk processing).
+
+*) RowMajor (reverse order of ColMajor)
+1st-Nth dimension: time (for video) or batch (for bulk processing).
+N+1'th dimension: columns (of size c)
+N+2'th dimension: rows (of size r)
+N+3'th dimension: channels (of size d)
+
+The returned tensor has one greater dimension than the input tensor, which is
+used to index each patch. The patch index in the output tensor depends on the
+data layout of the input tensor: the patch index is the 4'th dimension in
+ColMajor layout, and the 4'th from the last dimension in RowMajor layout.
+
+For example, given the following input tensor with the following dimension
+sizes:
+ *) depth:   2
+ *) rows:    3
+ *) columns: 5
+ *) batch:   7
+
+  Tensor<float, 4> tensor(2,3,5,7);
+  Tensor<float, 4, RowMajor> tensor_row_major = tensor.swap_layout();
+
+2x2 image patches can be extracted and indexed using the following code:
+
+*) 2D patch: ColMajor (patch indexed by second-to-last dimension)
+  Tensor<float, 5> twod_patch;
+  twod_patch = tensor.extract_image_patches<2, 2>();
+  // twod_patch.dimension(0) == 2
+  // twod_patch.dimension(1) == 2
+  // twod_patch.dimension(2) == 2
+  // twod_patch.dimension(3) == 3*5
+  // twod_patch.dimension(4) == 7
+
+*) 2D patch: RowMajor (patch indexed by the second dimension)
+  Tensor<float, 5, RowMajor> twod_patch_row_major;
+  twod_patch_row_major = tensor_row_major.extract_image_patches<2, 2>();
+  // twod_patch_row_major.dimension(0) == 7
+  // twod_patch_row_major.dimension(1) == 3*5
+  // twod_patch_row_major.dimension(2) == 2
+  // twod_patch_row_major.dimension(3) == 2
+  // twod_patch_row_major.dimension(4) == 2
+
+## Special Operations
+
+### `<Operation> cast<T>()`
+
+Returns a tensor of type T with the same dimensions as the original tensor.
+The returned tensor contains the values of the original tensor converted to
+type T.
+
+    Eigen::Tensor<float, 2> a(2, 3);
+    Eigen::Tensor<int, 2> b = a.cast<int>();
+
+This can be useful for example if you need to do element-wise division of
+Tensors of integers.  This is not currently supported by the Tensor library
+but you can easily cast the tensors to floats to do the division:
+
+    Eigen::Tensor<int, 2> a(2, 3);
+    a.setValues({{0, 1, 2}, {3, 4, 5}});
+    Eigen::Tensor<int, 2> b =
+        (a.cast<float>() / a.constant(2).cast<float>()).cast<int>();
+    cout << "a" << endl << a << endl << endl;
+    cout << "b" << endl << b << endl << endl;
+    =>
+    a
+    0 1 2
+    3 4 5
+
+    b
+    0 0 1
+    1 2 2
+
+
+### `<Operation>     eval()`
+
+TODO
+
+
+## Representation of scalar values
+
+Scalar values are often represented by tensors of size 1 and rank 0.For example
+Tensor<T, N>::maximum() currently returns a Tensor<T, 0>. Similarly, the inner
+product of 2 1d tensors (through contractions) returns a 0d tensor.
+
+## Limitations
+
+*   The number of tensor dimensions is currently limited to 250 when using a
+    compiler that supports cxx11. It is limited to only 5 for older compilers.
+*   The IndexList class requires a cxx11 compliant compiler. You can use an
+    array of indices instead if you don't have access to a modern compiler.
+*   On GPUs only floating point values are properly tested and optimized for.
+*   Complex and integer values are known to be broken on GPUs. If you try to use
+    them you'll most likely end up triggering a static assertion failure such as
+    EIGEN_STATIC_ASSERT(packetSize > 1, YOU_MADE_A_PROGRAMMING_MISTAKE)

+/** \class Tensor
+  * \ingroup CXX11_Tensor_Module
+  *
+  * \brief The tensor class.
+  *
+  * The %Tensor class is the work-horse for all \em dense tensors within Eigen.
+  *
+  * The %Tensor class encompasses only dynamic-size objects so far.
+  *
+  * The first two template parameters are required:
+  * \tparam Scalar_  Numeric type, e.g. float, double, int or `std::complex<float>`.
+  *                 User defined scalar types are supported as well (see \ref user_defined_scalars "here").
+  * \tparam NumIndices_ Number of indices (i.e. rank of the tensor)
+  *
+  * The remaining template parameters are optional -- in most cases you don't have to worry about them.
+  * \tparam Options_  A combination of either \b #RowMajor or \b #ColMajor, and of either
+  *                 \b #AutoAlign or \b #DontAlign.
+  *                 The former controls \ref TopicStorageOrders "storage order", and defaults to column-major. The latter controls alignment, which is required
+  *                 for vectorization. It defaults to aligning tensors. Note that tensors currently do not support any operations that profit from vectorization.
+  *                 Support for such operations (i.e. adding two tensors etc.) is planned.
+  *
+  * You can access elements of tensors using normal subscripting:
+  *
+  * \code
+  * Eigen::Tensor<double, 4> t(10, 10, 10, 10);
+  * t(0, 1, 2, 3) = 42.0;
+  * \endcode
+  *
+  * This class can be extended with the help of the plugin mechanism described on the page
+  * \ref TopicCustomizing_Plugins by defining the preprocessor symbol \c EIGEN_TENSOR_PLUGIN.
+  *
+  * <i><b>Some notes:</b></i>
+  *
+  * <dl>
+  * <dt><b>Relation to other parts of Eigen:</b></dt>
+  * <dd>The midterm development goal for this class is to have a similar hierarchy as Eigen uses for matrices, so that
+  * taking blocks or using tensors in expressions is easily possible, including an interface with the vector/matrix code
+  * by providing .asMatrix() and .asVector() (or similar) methods for rank 2 and 1 tensors. However, currently, the %Tensor
+  * class does not provide any of these features and is only available as a stand-alone class that just allows for
+  * coefficient access. Also, when fixed-size tensors are implemented, the number of template arguments is likely to
+  * change dramatically.</dd>

+  *
+  * The indices in the list can be known at compile time or at runtime. A mix
+  * of static and dynamic indices can also be provided if needed. The tensor
+  * code will attempt to take advantage of the indices that are known at
+  * compile time to optimize the code it generates.
+  *
+  * This functionality requires a c++11 compliant compiler. If your compiler
+  * is older you need to use arrays of indices instead.
+  *
+  * Several examples are provided in the cxx11_tensor_index_list.cpp file.

+/*****************************************************************
+ * TensorSyclExtractAccessor.h
+ *
+ * \brief:
+ * ExtractAccessor takes Expression placeHolder expression and the tuple of sycl
+ * buffers as an input. Using pre-order tree traversal, ExtractAccessor
+ * recursively calls itself for its children in the expression tree. The
+ * leaf node in the PlaceHolder expression is nothing but a container preserving
+ * the order of the actual data in the tuple of sycl buffer. By invoking the
+ * extract accessor for the PlaceHolder<N>, an accessor is created for the Nth
+ * buffer in the tuple of buffers. This accessor is then added as an Nth
+ * element in the tuple of accessors. In this case we preserve the order of data
+ * in the expression tree.
+ *
+ * This is the specialisation of extract accessor method for different operation
+ * type in the PlaceHolder expression.

+// Convolutional layers take in an input tensor of shape (D, R, C, B), or (D, C,
+// R, B), and convolve it with a set of filters, which can also be presented as
+// a tensor (D, K, K, M), where M is the number of filters, K is the filter
+// size, and each 3-dimensional tensor of size (D, K, K) is a filter. For
+// simplicity we assume that we always use square filters (which is usually the
+// case in images), hence the two Ks in the tensor dimension.  It also takes in
+// a few additional parameters:
+// Stride (S): The convolution stride is the offset between locations where we
+//             apply the filters.  A larger stride means that the output will be
+//             spatially smaller.
+// Padding (P): The padding we apply to the input tensor along the R and C
+//              dimensions.  This is usually used to make sure that the spatial
+//              dimensions of the output matches our intention.
+//
+// Two types of padding are often used:
+//   SAME: The pad value is computed so that the output will have size
+//         R/S and C/S.
+//   VALID: no padding is carried out.
+// When we do padding, the padded values at the padded locations are usually
+// zero.
+//
+// The output dimensions for convolution, when given all the parameters above,
+// are as follows:
+// When Padding = SAME: the output size is (B, R', C', M), where
+//   R' = ceil(float(R) / float(S))
+//   C' = ceil(float(C) / float(S))
+// where ceil is the ceiling function.  The input tensor is padded with 0 as
+// needed.  The number of padded rows and columns are computed as:
+//   Pr = ((R' - 1) * S + K - R) / 2
+//   Pc = ((C' - 1) * S + K - C) / 2
+// when the stride is 1, we have the simplified case R'=R, C'=C, Pr=Pc=(K-1)/2.
+// This is where SAME comes from - the output has the same size as the input has.
+// When Padding = VALID: the output size is computed as
+//   R' = ceil(float(R - K + 1) / float(S))
+//   C' = ceil(float(C - K + 1) / float(S))
+// and the number of padded rows and columns are computed in the same way as in
+// the SAME case.
+// When the stride is 1, we have the simplified case R'=R-K+1, C'=C-K+1, Pr=0,
+// Pc=0.

+  * \brief Pre-select whether to use a static or dynamic symmetry group
+  *
+  * When a symmetry group could in principle be determined at compile time,
+  * this template implements the logic whether to actually do that or whether
+  * to rather defer that to runtime.
+  *
+  * The logic is as follows:
+  * <dl>
+  * <dt><b>No generators (trivial symmetry):</b></dt>
+  * <dd>Use a trivial static group. Ideally, this has no performance impact
+  *     compared to not using symmetry at all. In practice, this might not
+  *     be the case.</dd>
+  * <dt><b>More than 4 generators:</b></dt>
+  * <dd>Calculate the group at run time, it is likely far too large for the
+  *     compiler to be able to properly generate it in a realistic time.</dd>
+  * <dt><b>Up to and including 4 generators:</b></dt>
+  * <dd>Actually enumerate all group elements, but then check how many there
+  *     are. If there are more than 16, it is unlikely that unrolling the
+  *     loop (as is done in the static compile-time case) is sensible, so
+  *     use a dynamic group instead. If there are at most 16 elements, actually
+  *     use that static group. Note that the largest group with 4 generators
+  *     still compiles with reasonable resources.</dd>
+  * </dl>
+  *
+  * Note: Example compile time performance with g++-4.6 on an Intenl Core i5-3470
+  *       with 16 GiB RAM (all generators non-redundant and the subgroups don't
+  *       factorize):
+  *
+  *          # Generators          -O0 -ggdb               -O2
+  *          -------------------------------------------------------------------
+  *          1                 0.5 s  /   250 MiB     0.45s /   230 MiB
+  *          2                 0.5 s  /   260 MiB     0.5 s /   250 MiB
+  *          3                 0.65s  /   310 MiB     0.62s /   310 MiB
+  *          4                 2.2 s  /   860 MiB     1.7 s /   770 MiB
+  *          5               130   s  / 13000 MiB   120   s / 11000 MiB
+  *
+  * It is clear that everything is still very efficient up to 4 generators, then
+  * the memory and CPU requirements become unreasonable. Thus we only instantiate
+  * the template group theory logic if the number of generators supplied is 4 or
+  * lower, otherwise this will be forced to be done during runtime, where the

+ *                "Ok kid, here is where it gets complicated."
+ *                         - Amelia Pond in the "Doctor Who" episode
+ *                           "The Big Bang"
+ *
+ * Dimino's algorithm
+ * ==================
+ *
+ * The following is Dimino's algorithm in sequential form:
+ *
+ * Input: identity element, list of generators, equality check,
+ *        multiplication operation
+ * Output: list of group elements
+ *
+ * 1. add identity element
+ * 2. remove identities from list of generators
+ * 3. add all powers of first generator that aren't the
+ *    identity element
+ * 4. go through all remaining generators:
+ *        a. if generator is already in the list of elements
+ *                -> do nothing
+ *        b. otherwise
+ *                i.   remember current # of elements
+ *                     (i.e. the size of the current subgroup)
+ *                ii.  add all current elements (which includes
+ *                     the identity) each multiplied from right
+ *                     with the current generator to the group
+ *                iii. add all remaining cosets that are generated
+ *                     by products of the new generator with itself
+ *                     and all other generators seen so far
+ *
+ * In functional form, this is implemented as a long set of recursive
+ * templates that have a complicated relationship.
+ *
+ * The main interface for Dimino's algorithm is the template
+ * enumerate_group_elements. All lists are implemented as variadic
+ * type_list<typename...> and numeric_list<typename = int, int...>
+ * templates.
+ *
+ * 'Calling' templates is usually done via typedefs.
+ *
+ * This algorithm is an extended version of the basic version. The
+ * extension consists in the fact that each group element has a set
+ * of flags associated with it. Multiplication of two group elements
+ * with each other results in a group element whose flags are the
+ * XOR of the flags of the previous elements. Each time the algorithm
+ * notices that a group element it just calculated is already in the
+ * list of current elements, the flags of both will be compared and
+ * added to the so-called 'global flags' of the group.
+ *
+ * The rationale behind this extension is that this allows not only
+ * for the description of symmetries between tensor indices, but
+ * also allows for the description of hermiticity, antisymmetry and
+ * antihermiticity. Negation and conjugation each are specific bit
+ * in the flags value and if two different ways to reach a group
+ * element lead to two different flags, this poses a constraint on
+ * the allowed values of the resulting tensor. For example, if a
+ * group element is reach both with and without the conjugation
+ * flags, it is clear that the resulting tensor has to be real.
+ *
+ * Note that this flag mechanism is quite generic and may have other
+ * uses beyond tensor properties.
+ *
+ * IMPORTANT: 
+ *     This algorithm assumes the group to be finite. If you try to
+ *     run it with a group that's infinite, the algorithm will only
+ *     terminate once you hit a compiler limit (max template depth).
+ *     Also note that trying to use this implementation to create a
+ *     very large group will probably either make you hit the same
+ *     limit, cause the compiler to segfault or at the very least
+ *     take a *really* long time (hours, days, weeks - sic!) to
+ *     compile. It is not recommended to plug in more than 4
+ *     generators, unless they are independent of each other.

+// EventCount allows to wait for arbitrary predicates in non-blocking
+// algorithms. Think of condition variable, but wait predicate does not need to
+// be protected by a mutex. Usage:
+// Waiting thread does:
+//
+//   if (predicate)
+//     return act();
+//   EventCount::Waiter& w = waiters[my_index];
+//   ec.Prewait(&w);
+//   if (predicate) {
+//     ec.CancelWait(&w);
+//     return act();
+//   }
+//   ec.CommitWait(&w);
+//
+// Notifying thread does:
+//
+//   predicate = true;
+//   ec.Notify(true);
+//
+// Notify is cheap if there are no waiting threads. Prewait/CommitWait are not
+// cheap, but they are executed only if the preceeding predicate check has
+// failed.
+//
+// Algorihtm outline:
+// There are two main variables: predicate (managed by user) and state_.
+// Operation closely resembles Dekker mutual algorithm:
+// https://en.wikipedia.org/wiki/Dekker%27s_algorithm
+// Waiting thread sets state_ then checks predicate, Notifying thread sets
+// predicate then checks state_. Due to seq_cst fences in between these
+// operations it is guaranteed than either waiter will see predicate change
+// and won't block, or notifying thread will see state_ change and will unblock
+// the waiter, or both. But it can't happen that both threads don't see each
+// other changes, which would lead to deadlock.

+// RunQueue is a fixed-size, partially non-blocking deque or Work items.
+// Operations on front of the queue must be done by a single thread (owner),
+// operations on back of the queue can be done by multiple threads concurrently.
+//
+// Algorithm outline:
+// All remote threads operating on the queue back are serialized by a mutex.
+// This ensures that at most two threads access state: owner and one remote
+// thread (Size aside). The algorithm ensures that the occupied region of the
+// underlying array is logically continuous (can wraparound, but no stray
+// occupied elements). Owner operates on one end of this region, remote thread
+// operates on the other end. Synchronization between these threads
+// (potential consumption of the last element and take up of the last empty
+// element) happens by means of state variable in each element. States are:
+// empty, busy (in process of insertion of removal) and ready. Threads claim
+// elements (empty->busy and ready->busy transitions) by means of a CAS
+// operation. The finishing transition (busy->empty and busy->ready) are done
+// with plain store as the element is exclusively owned by the current thread.
+//
+// Note: we could permit only pointers as elements, then we would not need
+// separate state variable as null/non-null pointer value would serve as state,
+// but that would require malloc/free per operation for large, complex values
+// (and this is designed to store std::function<()>).

+    *
+    * \brief Represents a rotation in a 3 dimensional space as three Euler angles.
+    *
+    * Euler rotation is a set of three rotation of three angles over three fixed axes, defined by the EulerSystem given as a template parameter.
+    * 
+    * Here is how intrinsic Euler angles works:
+    *  - first, rotate the axes system over the alpha axis in angle alpha
+    *  - then, rotate the axes system over the beta axis(which was rotated in the first stage) in angle beta
+    *  - then, rotate the axes system over the gamma axis(which was rotated in the two stages above) in angle gamma
+    *
+    * \note This class support only intrinsic Euler angles for simplicity,
+    *  see EulerSystem how to easily overcome this for extrinsic systems.
+    *
+    * ### Rotation representation and conversions ###
+    *
+    * It has been proved(see Wikipedia link below) that every rotation can be represented
+    *  by Euler angles, but there is no singular representation (e.g. unlike rotation matrices).
+    * Therefore, you can convert from Eigen rotation and to them
+    *  (including rotation matrices, which is not called "rotations" by Eigen design).
+    *
+    * Euler angles usually used for:
+    *  - convenient human representation of rotation, especially in interactive GUI.
+    *  - gimbal systems and robotics
+    *  - efficient encoding(i.e. 3 floats only) of rotation for network protocols.
+    *
+    * However, Euler angles are slow comparing to quaternion or matrices,
+    *  because their unnatural math definition, although it's simple for human.
+    * To overcome this, this class provide easy movement from the math friendly representation
+    *  to the human friendly representation, and vise-versa.
+    *
+    * All the user need to do is a safe simple C++ type conversion,
+    *  and this class take care for the math.
+    * Additionally, some axes related computation is done in compile time.
+    *
+    * #### Euler angles ranges in conversions ####
+    *
+    * When converting some rotation to Euler angles, there are some ways you can guarantee
+    *  the Euler angles ranges.
+    *
+    * #### implicit ranges ####
+    * When using implicit ranges, all angles are guarantee to be in the range [-PI, +PI],
+    *  unless you convert from some other Euler angles.
+    * In this case, the range is __undefined__ (might be even less than -PI or greater than +2*PI).
+    * \sa EulerAngles(const MatrixBase<Derived>&)
+    * \sa EulerAngles(const RotationBase<Derived, 3>&)
+    *
+    * #### explicit ranges ####
+    * When using explicit ranges, all angles are guarantee to be in the range you choose.
+    * In the range Boolean parameter, you're been ask whether you prefer the positive range or not:
+    * - _true_ - force the range between [0, +2*PI]
+    * - _false_ - force the range between [-PI, +PI]
+    *
+    * ##### compile time ranges #####
+    * This is when you have compile time ranges and you prefer to
+    *  use template parameter. (e.g. for performance)
+    * \sa FromRotation()
+    *
+    * ##### run-time time ranges #####
+    * Run-time ranges are also supported.
+    * \sa EulerAngles(const MatrixBase<Derived>&, bool, bool, bool)
+    * \sa EulerAngles(const RotationBase<Derived, 3>&, bool, bool, bool)
+    *
+    * ### Convenient user typedefs ###
+    *
+    * Convenient typedefs for EulerAngles exist for float and double scalar,
+    *  in a form of EulerAngles{A}{B}{C}{scalar},
+    *  e.g. \ref EulerAnglesXYZd, \ref EulerAnglesZYZf.
+    *
+    * Only for positive axes{+x,+y,+z} Euler systems are have convenient typedef.
+    * If you need negative axes{-x,-y,-z}, it is recommended to create you own typedef with
+    *  a word that represent what you need.
+    *
+    * ### Example ###
+    *
+    * \include EulerAngles.cpp
+    * Output: \verbinclude EulerAngles.out
+    *
+    * ### Additional reading ###
+    *

+    * \brief Represents a fixed Euler rotation system.
+    *
+    * This meta-class goal is to represent the Euler system in compilation time, for EulerAngles.
+    *
+    * You can use this class to get two things:
+    *  - Build an Euler system, and then pass it as a template parameter to EulerAngles.
+    *  - Query some compile time data about an Euler system. (e.g. Whether it's tait bryan)
+    *
+    * Euler rotation is a set of three rotation on fixed axes. (see \ref EulerAngles)
+    * This meta-class store constantly those signed axes. (see \ref EulerAxis)
+    *
+    * ### Types of Euler systems ###
+    *
+    * All and only valid 3 dimension Euler rotation over standard
+    *  signed axes{+X,+Y,+Z,-X,-Y,-Z} are supported:
+    *  - all axes X, Y, Z in each valid order (see below what order is valid)
+    *  - rotation over the axis is supported both over the positive and negative directions.
+    *  - both tait bryan and proper/classic Euler angles (i.e. the opposite).
+    *
+    * Since EulerSystem support both positive and negative directions,
+    *  you may call this rotation distinction in other names:
+    *  - _right handed_ or _left handed_
+    *  - _counterclockwise_ or _clockwise_
+    *
+    * Notice all axed combination are valid, and would trigger a static assertion.
+    * Same unsigned axes can't be neighbors, e.g. {X,X,Y} is invalid.
+    * This yield two and only two classes:
+    *  - _tait bryan_ - all unsigned axes are distinct, e.g. {X,Y,Z}
+    *  - _proper/classic Euler angles_ - The first and the third unsigned axes is equal,
+    *     and the second is different, e.g. {X,Y,X}
+    *
+    * ### Intrinsic vs extrinsic Euler systems ###
+    *
+    * Only intrinsic Euler systems are supported for simplicity.
+    *  If you want to use extrinsic Euler systems,
+    *   just use the equal intrinsic opposite order for axes and angles.
+    *  I.e axes (A,B,C) becomes (C,B,A), and angles (a,b,c) becomes (c,b,a).
+    *
+    * ### Convenient user typedefs ###
+    *
+    * Convenient typedefs for EulerSystem exist (only for positive axes Euler systems),
+    *  in a form of EulerSystem{A}{B}{C}, e.g. \ref EulerSystemXYZ.
+    *
+    * ### Additional reading ###
+    *

+    *
+    * \tparam _AlphaAxis the first fixed EulerAxis
+    *

-  * \class JacobiSVD
-  *
-  * \brief Two-sided Jacobi SVD decomposition of a rectangular matrix
-  *
-  * \param MatrixType the type of the matrix of which we are computing the SVD decomposition
-  * \param QRPreconditioner this optional parameter allows to specify the type of QR decomposition that will be used internally
-  *                        for the R-SVD step for non-square matrices. See discussion of possible values below.
-  *
-  * SVD decomposition consists in decomposing any n-by-p matrix \a A as a product
-  *   \f[ A = U S V^* \f]
-  * where \a U is a n-by-n unitary, \a V is a p-by-p unitary, and \a S is a n-by-p real positive matrix which is zero outside of its main diagonal;
-  * the diagonal entries of S are known as the \em singular \em values of \a A and the columns of \a U and \a V are known as the left
-  * and right \em singular \em vectors of \a A respectively.
-  *
-  * Singular values are always sorted in decreasing order.
-  *
-  * This JacobiSVD decomposition computes only the singular values by default. If you want \a U or \a V, you need to ask for them explicitly.
-  *
-  * You can ask for only \em thin \a U or \a V to be computed, meaning the following. In case of a rectangular n-by-p matrix, letting \a m be the
-  * smaller value among \a n and \a p, there are only \a m singular vectors; the remaining columns of \a U and \a V do not correspond to actual
-  * singular vectors. Asking for \em thin \a U or \a V means asking for only their \a m first columns to be formed. So \a U is then a n-by-m matrix,
-  * and \a V is then a p-by-m matrix. Notice that thin \a U and \a V are all you need for (least squares) solving.
-  *
-  * Here's an example demonstrating basic usage:
-  * \include JacobiSVD_basic.cpp
-  * Output: \verbinclude JacobiSVD_basic.out
-  *
-  * This JacobiSVD class is a two-sided Jacobi R-SVD decomposition, ensuring optimal reliability and accuracy. The downside is that it's slower than
-  * bidiagonalizing SVD algorithms for large square matrices; however its complexity is still \f$ O(n^2p) \f$ where \a n is the smaller dimension and
-  * \a p is the greater dimension, meaning that it is still of the same order of complexity as the faster bidiagonalizing R-SVD algorithms.
-  * In particular, like any R-SVD, it takes advantage of non-squareness in that its complexity is only linear in the greater dimension.
-  *
-  * If the input matrix has inf or nan coefficients, the result of the computation is undefined, but the computation is guaranteed to
-  * terminate in finite (and reasonable) time.
-  *
-  * The possible values for QRPreconditioner are:
-  * \li ColPivHouseholderQRPreconditioner is the default. In practice it's very safe. It uses column-pivoting QR.
-  * \li FullPivHouseholderQRPreconditioner, is the safest and slowest. It uses full-pivoting QR.
-  *     Contrary to other QRs, it doesn't allow computing thin unitaries.
-  * \li HouseholderQRPreconditioner is the fastest, and less safe and accurate than the pivoting variants. It uses non-pivoting QR.
-  *     This is very similar in safety and accuracy to the bidiagonalization process used by bidiagonalizing SVD algorithms (since bidiagonalization
-  *     is inherently non-pivoting). However the resulting SVD is still more reliable than bidiagonalizing SVDs because the Jacobi-based iterarive
-  *     process is more reliable than the optimized bidiagonal SVD iterations.
-  * \li NoQRPreconditioner allows not to use a QR preconditioner at all. This is useful if you know that you will only be computing
-  *     JacobiSVD decompositions of square matrices. Non-square matrices require a QR preconditioner. Using this option will result in
-  *     faster compilation and smaller executable code. It won't significantly speed up computation, since JacobiSVD is always checking
-  *     if QR preconditioning is needed before applying it anyway.

-This unsupported package is about a divide and conquer algorithm to compute SVD.

-The implementation follows as closely as possible the following reference paper :

-The code documentation uses the same names for variables as the reference paper. The code, deflation included, is
-working  but there are a few things that could be optimised as explained in the TODOBdsvd.

-In the code comments were put at the line where would be the third step of the algorithm so one could simply add the call

-
-In the TODOBdcsvd we explain what is the main difficulty of the last part and suggest a reference paper to help solve it.

+  *
+  * \class BlockSparseMatrix
+  *
+  * \brief A versatile sparse matrix representation where each element is a block
+  *
+  * This class provides routines to manipulate block sparse matrices stored in a
+  * BSR-like representation. There are two main types :
+  *
+  * 1. All blocks have the same number of rows and columns, called block size
+  * in the following. In this case, if this block size is known at compile time,
+  * it can be given as a template parameter like
+  * \code
+  * BlockSparseMatrix<Scalar, 3, ColMajor> bmat(b_rows, b_cols);
+  * \endcode
+  * Here, bmat is a b_rows x b_cols block sparse matrix
+  * where each coefficient is a 3x3 dense matrix.
+  * If the block size is fixed but will be given at runtime,
+  * \code
+  * BlockSparseMatrix<Scalar, Dynamic, ColMajor> bmat(b_rows, b_cols);
+  * bmat.setBlockSize(block_size);
+  * \endcode
+  *
+  * 2. The second case is for variable-block sparse matrices.
+  * Here each block has its own dimensions. The only restriction is that all the blocks
+  * in a row (resp. a column) should have the same number of rows (resp. of columns).
+  * It is thus required in this case to describe the layout of the matrix by calling
+  * setBlockLayout(rowBlocks, colBlocks).
+  *
+  * In any of the previous case, the matrix can be filled by calling setFromTriplets().
+  * A regular sparse matrix can be converted to a block sparse matrix and vice versa.
+  * It is obviously required to describe the block layout beforehand by calling either
+  * setBlockSize() for fixed-size blocks or setBlockLayout for variable-size blocks.
+  *
+  * \tparam _Scalar The Scalar type
+  * \tparam _BlockAtCompileTime The block layout option. It takes the following values
+  * Dynamic : block size known at runtime
+  * a numeric number : fixed-size block known at compile time

+ *
+ *
+ * SYNOPSIS:
+ *
+ * int N;
+ * Scalar x, y, coef[N+1];
+ *
+ * y = polevl<decltype(x), N>( x, coef);
+ *
+ *
+ *
+ * DESCRIPTION:
+ *
+ * Evaluates polynomial of degree N:
+ *
+ *                     2          N
+ * y  =  C  + C x + C x  +...+ C x
+ *        0    1     2          N
+ *
+ * Coefficients are stored in reverse order:
+ *
+ * coef[0] = C  , ..., coef[N] = C  .
+ *            N                   0
+ *
+ *  The function p1evl() assumes that coef[N] = 1.0 and is
+ * omitted from the array.  Its calling arguments are
+ * otherwise the same as polevl().
+ *
+ *
+ * The Eigen implementation is templatized.  For best speed, store
+ * coef as a const array (constexpr), e.g.
+ *
+ * const double coef[] = {1.0, 2.0, 3.0, ...};

+     *
+     * float a, b, x, y, betaincf();
+     *
+     * y = betaincf( a, b, x );
+     *
+     *
+     * DESCRIPTION:
+     *
+     * Returns incomplete beta integral of the arguments, evaluated
+     * from zero to x.  The function is defined as
+     *
+     *                  x
+     *     -            -
+     *    | (a+b)      | |  a-1     b-1
+     *  -----------    |   t   (1-t)   dt.
+     *   -     -     | |
+     *  | (a) | (b)   -
+     *                 0
+     *
+     * The domain of definition is 0 <= x <= 1.  In this
+     * implementation a and b are restricted to positive values.
+     * The integral from x to 1 may be obtained by the symmetry
+     * relation
+     *
+     *    1 - betainc( a, b, x )  =  betainc( b, a, 1-x ).
+     *
+     * The integral is evaluated by a continued fraction expansion.
+     * If a < 1, the function calls itself recursively after a
+     * transformation to increase a to a+1.
+     *
+     * ACCURACY (float):
+     *
+     * Tested at random points (a,b,x) with a and b in the indicated
+     * interval and x between 0 and 1.
+     *
+     * arithmetic   domain     # trials      peak         rms
+     * Relative error:
+     *    IEEE       0,30       10000       3.7e-5      5.1e-6
+     *    IEEE       0,100      10000       1.7e-4      2.5e-5
+     * The useful domain for relative error is limited by underflow
+     * of the single precision exponential function.
+     * Absolute error:
+     *    IEEE       0,30      100000       2.2e-5      9.6e-7

+This directory contains contributions from various users.
+They are provided "as is", without any support. Nevertheless,
+most of them are subject to be included in Eigen in the future.
+
+In order to use an unsupported module you have to do either:
+
+ - add the path_to_eigen/unsupported directory to your include path and do:
+   #include <Eigen/ModuleHeader>
+
+ - or directly do:
+   #include <unsupported/Eigen/ModuleHeader>
+
+
+If you are interested in contributing to one of them, or have other stuff
+you would like to share, feel free to contact us:
+http://eigen.tuxfamily.org/index.php?title=Main_Page#Mailing_list
+
+Any kind of contributions are much appreciated, even very preliminary ones.
+However, it:
+ - must rely on Eigen,
+ - must be highly related to math,
+ - should have some general purpose in the sense that it could
+   potentially become an offical Eigen module (or be merged into another one).
+
+In doubt feel free to contact us. For instance, if your addons is very too specific
+but it shows an interesting way of using Eigen, then it could be a nice demo.

-<https://github.com/libigl/libigl/>
+Documentation, tutorial, and instructions at <https://libigl.github.io>.
 
-> Get started with:
->
-```bash
-git clone --recursive https://github.com/libigl/libigl.git
-```
-
-libigl is a simple C++ geometry processing library. We have a wide
-functionality including construction of sparse discrete differential geometry
-operators and finite-elements matrices such as the cotangent Laplacian and
-diagonalized mass matrix, simple facet and edge-based topology data structures,
-mesh-viewing utilities for OpenGL and GLSL, and many core functions for matrix
-manipulation which make [Eigen](http://eigen.tuxfamily.org) feel a lot more
-like MATLAB.
-
-It is **a header-only library**. You do not need to compile anything to use,
-just include igl headers (e.g. `#include <igl/cotmatrix.h>`) and run.  Each
-header file contains a single function (e.g. `igl/cotmatrix.h` contains
-`igl::cotmatrix()`). Most are tailored to operate on a generic triangle mesh
-stored in an n-by-3 matrix of vertex positions `V` and an m-by-3 matrix of
-triangle indices `F`.
-
-_Optionally_ the library may also be [pre-compiled](http://libigl.github.io/libigl/static-library/) into a statically
-linked library, for faster compile times with your projects. This only effects
-compile time (run-time performance and behavior is identical). If in doubt, use
-the header-only default mode: (i.e. just include the headers you want to use).
-
-We use the [Eigen](http://eigen.tuxfamily.org) library heavily in our code. Our
-group prototypes a lot in MATLAB, and we have a useful [MATLAB to libigl+Eigen
-conversion table](matlab-to-eigen.html).
-
-We regularly test compiling our library on Mac OS X with clang, Linux with gcc
-and Windows with Visual Studio 2015 Community Edition.
-
-## Tutorial
-
-As of version 1.0, libigl includes an introductory
-[tutorial](http://libigl.github.io/libigl/tutorial) that covers many functionalities.
-
-## libigl Example Project
-
-We provide a [blank project example](https://github.com/libigl/libigl-example-project) showing how to use libigl and cmake. Feel free and encouraged to copy or fork this project as a way of starting a new personal project using libigl.
-
-## Coding Guidelines and Tips
-
-libigl follows strict coding guidelines, please take a look [here](http://libigl.github.io/libigl/style-guidelines) before submitting your pull requests. We also have a set of [general coding tips](http://libigl.github.io/libigl/coding-guidelines) on how to code a geometry processing research project.
-
-## Installation
-
-Libigl is a **header-only** library. You do **not** need to build anything to
-install.  Simply add `libigl/include` to your include path and include relevant
-headers.  Here is a small "Hello, World" program:
-
-```cpp
-#include <igl/cotmatrix.h>
-#include <Eigen/Dense>
-#include <Eigen/Sparse>
-#include <iostream>
-int main()
-{
-  Eigen::MatrixXd V(4,2);
-  V<<0,0,
-     1,0,
-     1,1,
-     0,1;
-  Eigen::MatrixXi F(2,3);
-  F<<0,1,2,
-     0,2,3;
-  Eigen::SparseMatrix<double> L;
-  igl::cotmatrix(V,F,L);
-  std::cout<<"Hello, mesh: "<<std::endl<<L*V<<std::endl;
-  return 0;
-}
-```
-
-If you save this in `hello.cpp`, then you could compile this with (assuming
-Eigen is installed in `/usr/local/include/eigen3`):
-
-```bash
-g++ -std=c++11 -I/usr/local/include/eigen3 -I./libigl/include/ hello.cpp -o hello
-```
-
-Running `./hello` would then produce
-
-```
-Hello, mesh:
- 0.5  0.5
--0.5  0.5
--0.5 -0.5
- 0.5 -0.5
-```
-
-## Dependencies
-Dependencies are on a per-include basis and the majority of the functions in
-libigl depends only on the [Eigen](http://eigen.tuxfamily.org) library.
-
-For more information see our [tutorial](http://libigl.github.io/libigl/tutorial).
-
-### Optional Dependencies
-
-Libigl compartmentalizes its **optional** dependences via its directory
-organization in the `include/` folder. All header files located _directly_ in
-the `include/igl/` folder have only stl and Eigen as dependencies. For example,
-all of the headers that depend on CGAL are located in `include/igl/copyleft/cgal`.
-For a full list of _optional_ dependencies check `optional/CMakeLists.txt`.
-
-### GCC and the Optional CGAL Dependency
-The `include/igl/copyleft/cgal/*.h` headers depend on CGAL. It has come to
-our attention that CGAL does not work properly with GCC 4.8. To the best of
-our knowledge, GCC 4.7 and clang will work correctly.
-
-### OpenMP and Windows
-Some of our functions will take advantage of OpenMP if available. However, it
-has come to our attention that Visual Studio + Eigen + OpenMP does not work
-properly. Since we use OpenMP only to improve performance, we recommend
-avoiding OpenMP on Windows or proceeding with caution.
-
-## Download
-You can keep up to date by cloning a read-only copy of our GitHub
-[repository](https://github.com/libigl).
-
-## Known Issues
-We rely heavily on Eigen. Nearly all inputs and outputs are Eigen matrices of
-some kind. However, we currently _only_ officially support Eigen's default
-column-major ordering. That means, we **do not** expect our code to work for
-matrices using the `Eigen::RowMajor` flag. If you can, change definitions like:
-
-```cpp
-Eigen::Matrix<double, Eigen::Dynamic, 3, Eigen::RowMajor> A;
-```
-
-to
-
-```cpp
-Eigen::Matrix<double, Eigen::Dynamic, 3, Eigen::ColMajor> A;
-// or simply
-Eigen::Matrix<double, Eigen::Dynamic, 3> A;
-```
-
-We hope to fix this, or at least identify which functions are safe (many of
-them probably work just fine). This requires setting up unit testing, which is
-a major _todo_ for our development.
-
-## Git Submodules
-Libigl uses git submodules for its _optional_ dependencies,
-in particular, those needed by the OpenGL viewer to run the examples in the
-[tutorial](http://libigl.github.io/libigl/tutorial). Git submodules allow use to treat clones of
-other libraries as sub-directories within ours while separating our commits.
-Read the [documentation](http://git-scm.com/docs/git-submodule) for a detailed
-explanation, but essentially our libigl repo stores a hash for each of its
-subrepos containing which version to update to. When a change is introduced in
-a dependencies repo we can incorporate that change by pulling in our sub-repo
-and updating (i.e.  committing) that change to the hash.
-
-When pulling new changes to libigl it's also a good idea to update changes to
-subrepos:
-
-```bash
-git pull
-git submodule update --recursive
-```
-
-## Unit Testing
-
-Libigl maintains [separate
-repository](https://github.com/libigl/libigl-unit-tests) for unit testing.
-

-// ReAntTweakBar is a minimal wrapper for the AntTweakBar library that allows

-// AntTweakBar to use ReAntTweakBar is trivial.
-// 
-// Many (but not all) variable types are supported. I'll try to keep track them
-// here:
-//   TW_TYPE_BOOLCPP
-//   TW_TYPE_QUAT4F
-//   TW_TYPE_QUAT4D

-// 
-// I'm working on adding the rest on an as-needed basis. Adding a new type only
