mxIsStruct
True if a structuremxArray
#include "matrix.h" bool mxIsStruct(const mxArray *array_ptr);array_ptr
true if array_ptr points to a structure array; otherwise, returns false.
Use mxIsStruct to determine if array_ptr points to a structure mxArray. Many routines (for example, mxGetFieldName and mxSetField) require a structure mxArray as an argument.
