mxCreateCellMatrix (C and Fortran)

2-D cell array

C Syntax

#include "matrix.h"
mxArray *mxCreateCellMatrix(mwSize m, mwSize n);

Fortran Syntax

#include "fintrf.h"
mwPointer mxCreateCellMatrix(m, n)
mwSize m, n



Number of rows


Number of columns


Pointer to the created mxArray. 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.


Use mxCreateCellMatrix to create an m-by-n two-dimensional cell mxArray. The created cell mxArray is unpopulated; mxCreateCellMatrix initializes each cell to NULL in C (0 in Fortran). To put data into cells, call mxSetCell.

mxCreateCellMatrix is identical to mxCreateCellArray except that mxCreateCellMatrix can create two-dimensional mxArrays only, but mxCreateCellArray can create mxArrays having any number of dimensions greater than 1.
