mxCreateCellArray

Create unpopulated N-dimensional cell mxArray

C Syntax

• #include "matrix.h"
  mxArray *mxCreateCellArray(int ndim, const int *dims);
  

Arguments

ndim
   The desired number of dimensions in the created cell. For example, to create a three-dimensional cell mxArray, set ndim to 3.

dims
   The dimensions array. Each element in the dimensions array contains the size of the mxArray in that dimension. For example, setting dims[0] to 5 and dims[1] to 7 establishes a 5-by-7 mxArray. In most cases, there should be ndim elements in the dims array.

Returns

A pointer to the created cell mxArray, if successful. If unsuccessful in a stand-alone (nonMEX-file) application, mxCreateCellArray returns NULL. If unsuccessful in a MEX-file, the MEX-file terminates and control returns to the MATLAB prompt. The most common cause of failure is insufficient free heap space.

Description

Use mxCreateCellArray to create a cell mxArray whose size is defined by ndim and dims. For example, to establish a three-dimensional cell mxArray having dimensions 4-by-8-by-7, set

• ndim = 3;
  dims[0] = 4; dims[1] = 8; dims[2] = 7;
  

The created cell mxArray is unpopulated; that is, mxCreateCellArray initializes each cell to NULL. To put data into a cell, call mxSetCell.
