mxCreateCharArray (C and Fortran) - Create unpopulated N-D string `mxArray`

C Syntax

#include "matrix.h"
mxArray *mxCreateCharArray(mwSize ndim, const mwSize *dims);

Fortran Syntax

mwPointer mxCreateCharArray(ndim, dims)
mwSize ndim, dims

Arguments

ndim: The desired number of dimensions in the string mxArray. You must specify a positive number. If you specify 0, 1, or 2, mxCreateCharArray creates a two-dimensional mxArray.
dims: The dimensions array. Each element in the dimensions array contains the size of the array in that dimension. For example, in C, setting dims[0] to 5 and dims[1] to 7 establishes a 5-by-7 mxArray. In Fortran, setting dims(1) to 5 and dims(2) to 7 establishes a 5-by-7 character mxArray. The dims array must have at least ndim elements.

Returns

A pointer to the created string mxArray, if successful. If unsuccessful in a stand alone (non-MEX-file) application, mxCreateCharArray returns NULL in C (0 in Fortran). If unsuccessful in a MEX-file, the MEX-file terminates and control returns to the MATLAB^® prompt. Insufficient free heap space is the only reason for mxCreateCharArray to be unsuccessful.

Description

Call mxCreateCharArray to create an N-dimensional string mxArray. The created mxArray is unpopulated; that is, mxCreateCharArray initializes each cell to NULL in C (0 in Fortran).

Any trailing singleton dimensions specified in the dims argument are automatically removed from the resulting array. For example, if ndim equals 5 and dims equals [4 1 7 1 1], the resulting array is given the dimensions 4-by-1-by-7.
