Get (as a string) an mxArray's class

#include "matrix.h"
const char *mxGetClassName(const mxArray *array_ptr);

Arguments

array_ptr

Pointer to an mxArray.

Returns

The class (category) of array_ptr.

Description

Call mxGetClassId to determine the class of an mxArray. The class of an mxArray identifies the kind of data the mxArray is holding. For example, if array_ptr points to a sparse mxArray, then mxGetClassID returns "mxSPARSE_CLASS".

mxGetClassID is similar to mxGetClassName, except that the former returns the class as an enumerated value and the latter returns the class as a string.

Example

See mxGetClassName.c in the mx subdirectory of the examples directory.
