mxIsInt64 (C and Fortran)

Determine whether array represents data as signed 64-bit integers

C Syntax

#include "matrix.h"
bool mxIsInt64(const mxArray *pm);

Fortran Syntax

integer*4 mxIsInt64(pm)
mwPointer pm

Arguments

pm

Pointer to an mxArray

Returns

Logical 1 (true) if the array stores its data as signed 64-bit integers, and logical 0 (false) otherwise.

Description

Use mxIsInt64 to determine whether the specified array represents its real and imaginary data as 64-bit signed integers.

In C, calling mxIsInt64 is equivalent to calling:

mxGetClassID(pm) == mxINT64_CLASS

In Fortran, calling mxIsInt64 is equivalent to calling:

mxGetClassName(pm) == 'int64'
