mxIsInt32 (C and Fortran)

Determine whether array represents data as signed 32-bit integers

C Syntax

#include "matrix.h"
bool mxIsInt32(const mxArray *pm);

Fortran Syntax

integer*4 mxIsInt32(pm)
mwPointer pm



Pointer to an mxArray


Logical 1 (true) if the array stores its data as signed 32-bit integers, and logical 0 (false) otherwise.


Use mxIsInt32 to determine whether the specified array represents its real and imaginary data as 32-bit signed integers.

In C, calling mxIsInt32 is equivalent to calling:

mxGetClassID(pm) == mxINT32_CLASS

In Fortran, calling mxIsInt32 is equivalent to calling:

mxGetClassName(pm) == 'int32'
