mxIsUint64 (C and Fortran)

Determine whether array represents data as unsigned 64-bit integers

C Syntax

#include "matrix.h"
bool mxIsUint64(const mxArray *pm);

Fortran Syntax

#include "fintrf.h"
integer*4 mxIsUint64(pm)
mwPointer pm

Arguments

pm

Pointer to an mxArray

Returns

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

Description

Use mxIsUint64 to determine whether the specified mxArray represents its real and imaginary data as 64-bit unsigned integers.

In C, calling mxIsUint64 is equivalent to calling:

mxGetClassID(pm) == mxUINT64_CLASS

In Fortran, calling mxIsUint64 is equivalent to calling:

mxGetClassName(pm) .eq. 'uint64'
