True if mxArray represents its data as signed 8-bit integers

#include "matrix.h"
bool mxIsInt8(const mxArray *array_ptr);

array_ptr

Pointer to an mxArray.

true if the array stores its data as signed 8-bit integers; otherwise, returns false.

Use mxIsInt8 to determine whether or not the specified array represents its real and imaginary data as 8-bit signed integers.

Calling mxIsInt8 is equivalent to calling

mxGetClassID(array_ptr) == mxINT8_CLASS
