mxIsEmpty (C and Fortran)

Determine whether array is empty

C Syntax

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

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

Logical 1 (true) if the mxArray is empty, and logical 0 (false) otherwise.

Use mxIsEmpty to determine whether an mxArray contains no data. An mxArray is empty if the size of any of its dimensions is 0.
