mxIsNumeric (C and Fortran) - Determine whether mxArray is numeric

C Syntax

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

Fortran Syntax

integer*4 mxIsNumeric(pm)
mwPointer pm

Arguments

pm

Pointer to an mxArray

Returns

Logical 1 (true) if the array can contain numeric data. The following class IDs represent storage types for arrays that can contain numeric data:

• mxDOUBLE_CLASS

• mxSINGLE_CLASS

• mxINT8_CLASS

• mxUINT8_CLASS

• mxINT16_CLASS

• mxUINT16_CLASS

• mxINT32_CLASS

• mxUINT32_CLASS

• mxINT64_CLASS

• mxUINT64_CLASS

Logical 0 (false) if the array cannot contain numeric data.

Description

Call mxIsNumeric to determine whether the specified array contains numeric data. If the specified array has a storage type that represents numeric data, mxIsNumeric returns logical 1 (true). Otherwise, mxIsNumeric returns logical 0 (false).

Call mxGetClassID to determine the exact storage type.
