matPutArray (MATLAB Application Program Interface)

Write mxArrays into MAT-files

C Syntax

#include "mat.h"
int matPutArray(MATFile *mfp, const mxArray *mp);

Arguments

mfp

Pointer to MAT-file information.

mp

mxArray pointer.

Description

This routine allows you to put an mxArray into a MAT-file.

matPutArray writes mxArray mp to the MAT-file mfp. If the mxArray does not exist in the MAT-file, it is appended to the end. If an mxArray with the same name already exists in the file, the existing mxArray is replaced with the new mxArray by rewriting the file. The size of the new mxArray can be different than the existing mxArray.

matPutArray returns 0 if successful and nonzero if an error occurs. Use feof and ferror from the Standard C Library along with matGetFp to determine status.

Example

See matcreat.c and matdgns.c in the eng_mat subdirectory of the examples directory for sample programs that illustrate how to use the MATLAB MAT-file routines in a C program.
