Mat_CreateVer,

#include <matio.h>

mat_t *
Mat_CreateVer(const char *matname, const char *hdr_str, enum mat_ft mat_file_ver);

mat_t *
Mat_Create(const char *matname, const char *hdr_str);

The () function creates a MATLAB .mat file opened for write access. The hdr_str is a string written in the file header of MAT version 5 and 7.3 (HDF) files. Only the first 128 bytes of the string is written. If hdr_str is NULL, then a default string is written that contains the platform, date, matio library version.

The argument specifies the MAT file version to create. The matio library can write version 5 files (MAT_FT_MAT5), and an HDF5 file format introduced in MATLAB version 7.3 (MAT_FT_MAT73).

The () function is equivalent to calling Mat_CreateVer() with MAT_FT_DEFAULT as the file version.

#include <stdlib.h>

    matfp = Mat_CreateVer(argv[1],NULL,MAT_FT_73);
    if ( NULL == matfp ) {
        fprintf(stderr,"Error creating MAT file %s0,argv[1]);
        return EXIT_FAILURE;
    }

    Mat_Close(matfp);
    return EXIT_SUCCESS;
}
