NAME

       Mat_VarWrite — Writes a MATLAB variable to a MATLAB MAT file.

SYNOPSIS

       #include <matio.h>

       int
       Mat_VarWrite(mat_t *matfp, matvar_t *matvar, enum matio_compression compress);

DESCRIPTION

       The  Mat_VarWrite() function writes the MATLAB variable matvar to the MAT file matfp which must be opened
       for writing. If the MAT file is a version 5 or HDF5 MAT file, the compress option allows the variable  to
       be written using zlib compression if available.  If compression is not available, the variable is written
       uncompressed.

RETURN VALUES

       The  function  returns  0  if the variable was successfully written to the MAT file.  Otherwise, an error
       value is returned.

EXAMPLES

       This example program creates a MAT file named by the first  argument  to  the  program,  and  writes  the
       variable named m_pi to the file.

       #include <math.h>
       #include "matio.h"

       int
       main(int argc, char **argv)
       {
           mat_t    *matfp;
           matvar_t *matvar;
           size_t    dims[2] = {1, 1};
           double    m_pi = M_PI;

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

           matvar = Mat_VarCreate("m_pi", MAT_C_DOUBLE, MAT_T_DOUBLE,
                                  2, dims, &m_pi, 0);
           if ( NULL != matvar ) {
               Mat_VarWrite(matfp, matvar, MAT_COMPRESSION_ZLIB);
               Mat_VarFree(matvar);
           }

           Mat_Close(matfp);
           return EXIT_SUCCESS;
       }
