True if mxArray represents its data as single-precision, floating-point numbers

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

array_ptr

Pointer to an mxArray.

true if the array stores its data as single-precision, floating-point numbers; otherwise, returns false.

Use mxIsSingle to determine whether or not the specified array represents its real and imaginary data as single-precision, floating-point numbers.

Calling mxIsDouble is equivalent to calling

mxGetClassID(array_ptr) == mxSINGLE_CLASS
