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

     The Mat_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.
