Determine whether array represents data as unsigned 32-bit integers
Logical 1 (true) if the mxArray stores its data as unsigned 32-bit integers, and logical 0 (false) otherwise.
Use mxIsUint32 to determine whether the specified mxArray represents its real and imaginary data as 32-bit unsigned integers.
In C, calling mxIsUint32 is equivalent to calling:
mxGetClassID(pm) == mxUINT32_CLASS
In Fortran, calling mxIsUint32 is equivalent to calling:
mxGetClassName(pm) .eq. 'uint32'
