Mat_VarGetStructsLinear —
Linearly index a structure variable
#include
<matio.h>
matvar_t *
Mat_VarGetStructsLinear(const matvar_t
*matvar, int start, int
stride, int edge, int
copy_fields);
The
Mat_VarGetStructsLinear()
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 indexing 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 original array must
have at least start+(stride-1)*edge+1 elements. 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.
A subarray of the original structure array, or NULL if there is an error.
