.Sh NAME
.Nm Mat_CreateVer ,
.Nm Mat_Create
.Nd Creates a MATLAB MAT file.
.Sh SYNOPSIS
.Fd #include <matio.h>
.Ft mat_t *
.Fo Mat_CreateVer
.Fa "const char *matname"
.Fa "const char *hdr_str"
.Fa "enum mat_ft mat_file_ver"

.Ft mat_t *

.Fa "const char *matname"
.Fa "const char *hdr_str"
.Fc
.Sh DESCRIPTION
The
.Fn Mat_CreateVer
function creates a MATLAB MAT file opened for write access.
The
.Em 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
.Em hdr_str
is NULL, then a default string is written that contains the platform, date,
matio library version.
.Pp
The
.Em mat_file_ver
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).
.Pp
The
.Fn Mat_Create
function is equivalent to calling
.Fn Mat_CreateVer
with MAT_FT_DEFAULT as the file version.
.Sh EXAMPLES
.Bd -literal
#include <stdlib.h>
#include <stdio.h>
#include "matio.h"

int main(int argc,char **argv)
{
    mat_t *matfp;

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

    Mat_Close(matfp);
    return EXIT_SUCCESS;
}
