NAME
Mat_VarGetStructs —
Index a structure variable using slices of each dimension
SYNOPSIS
#include <matio.h>
matvar_t *
Mat_VarGetStructs(const matvar_t
*matvar, int *start, int
*stride, int *edge, int
copy_fields);
DESCRIPTION
TheMat_VarGetStructs() function selects a subarray from
a structure array matvar. Each of the elements in the
subarray contains all of the fields of the structure. The index of each
dimension starts at the start element in the array (0
being the first element), and reads every stride values
(1 being every element, 2 every other element, etc.). The total number of
elements in the subarray is specified as edge. The
copy_fields option specifies whether the fields of the
original structure are copied for the new subarray. If set to 0, the returned
structure array's fields have the same pointer as the original array, and the
data field of the subarray structure. The subarray is
marked with the conserve memory flag indicating that the fields should not be
free'd. They are free'd when the original structure is free'd.
RETURN VALUES
A subarray of the original structure array, or NULL if there is an error.SEE ALSO
