1-N array initialized to specified string
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.
Use mxCreateString to create a string mxArray initialized to str. Many MATLAB functions (for example, strcmp and upper) require string array inputs.
Free the string mxArray when you are finished using it. To free a string mxArray, call mxDestroyArray.
