mxDuplicateArray (C and Fortran)

Make deep copy of array

C Syntax

#include "matrix.h"
mxArray *mxDuplicateArray(const mxArray *in);

Fortran Syntax

#include "fintrf.h"
mwPointer mxDuplicateArray(in)
mwPointer in

Arguments

in

Pointer to the mxArray you want to copy

Returns

Pointer to the created mxArray, if successful. If unsuccessful in a standalone (non-MEX file) application, returns NULL in C (0 in Fortran). If unsuccessful in a MEX file, the MEX file terminates and returns control to the MATLAB® prompt. The function is unsuccessful when there is not enough free heap space to create the mxArray.

Description

mxDuplicateArray makes a deep copy of an array, and returns a pointer to the copy. A deep copy refers to a copy in which all levels of data are copied. For example, a deep copy of a cell array copies each cell and the contents of each cell (if any).
