mxSetClassName (C)

Structure array to MATLAB object array

Use mxSetClassName for classes defined without a classdef statement.

C Syntax

#include "matrix.h"
int mxSetClassName(mxArray *array_ptr, const char *classname);

Arguments

array_ptr: Pointer to an mxArray of class mxSTRUCT_CLASS
classname: Object class to which to convert array_ptr

Returns

0 if successful, and nonzero otherwise. One cause of failure is that array_ptr is not a structure mxArray. Call mxIsStruct to determine whether array_ptr is a structure.

Description

mxSetClassName converts a structure array to an object array, to be saved later to a MAT-file. MATLAB^® does not register or validate the object until it is loaded by the LOAD command. If the specified classname is an undefined class within MATLAB, then LOAD converts the object back to a simple structure array.
