// .dmat is a simple ascii matrix file type, defined as follows. The first line
|
|
// is always:
|
|
// <#columns> <#rows>
|
|
// Then the coefficients of the matrix are given separated by whitespace with
|
|
// columns running fastest.
|
|
//
|
|
// Example:
|
|
// The matrix m = [1 2 3; 4 5 6];
|
|
// corresponds to a .dmat file containing:
|
|
// 3 2
|
|
// 1 4 2 5 3 6
