1-D array initialized to specified string

C Syntax

#include "matrix.h"

Description

Use mxCreateString to create an mxArray initialized from str.

Call mxDestroyArray when you finish using the mxArray.

Input Arguments

str — String

const char *

String, specified as const char *. This string can be encoded using UTF-8 or, for backward compatibility, the local code page (LCP) encoding.

Output Arguments

Pointer to an mxArray, specified as mxArray *, if successful.

The function is unsuccessful when there is not enough free heap space to create the mxArray.
