mxSetName (MATLAB Application Program Interface)

Set the name of an mxArray

#include "matrix.h"
void mxSetName(mxArray *array_ptr, const char *name);

Arguments

array_ptr
Pointer to an mxArray.

name
The name you are assigning to the mxArray. The specified name can be up to mxMAXNAM characters, where mxMAXNAM is a constant defined in the matrix.h header file. If you specify a name longer than mxMAXNAM-1 characters, then mxSetName assigns only the first mxMAXNAM-1 characters to the name.

Description

Call mxSetName to establish a name for an mxArray or to change an existing name.

mxSetName assigns the characters in name to a fixed-width section of memory. Do not deallocate this memory.

Examples

Create an mxArray. Then, give it a name.

mxArray   *array_ptr;

 /* Create a 5-by-7 real array. */ 
   array_ptr = mxCreateDoubleMatrix(5, 7, mxREAL);

 /* Name the array "Grapes" */
   mxSetName(array_ptr, "Grapes");

   ...

For an additional example, see mxsetname.c in the mx subdirectory of the examples directory.
