function [field_i mesh_i] = GetField_Range(field, mesh, range)

|
|
% Get a field dump subset within a given mesh range
|
|
%
|
|
% example:
|
|
% % specify a mesh range
|
|
% range{1} = [0 150] * 1e-3; % x in range 0..150mm
|
|
% range{2} = [0]; % only one line close to y==0
|
|
% range{3} = []; % no range restriction
|
|
%
|
|
% % read hdf data
|
|
% [field mesh] = ReadHDF5Dump('Et.h5');
|
|
% % extract a ranged subset
|
|
% [field_i mesh_i] = GetField_Range(field, mesh, range);
|
|
%
|
|
% %or both steps in one with the same result:
|
|
% [field_i mesh_i] = ReadHDF5Dump('Et.h5','Range', range);
