MAT_VARREAD(3)		     Library Functions Manual		  MAT_VARREAD(3)

NAME
     Mat_VarRead  -- Reads the information and data for a specific variable in a
     MATLAB MAT file.

SYNOPSIS
     #include <matio.h>

     matvar_t *
     Mat_VarRead(mat_t *matfp, const char *name);

DESCRIPTION
     The Mat_VarRead() function reads the information and data for the	variable
     name in the open MAT file.

RETURN VALUES
     If  the variable was found in the MAT file and successfully read, a pointer
     to the MATLAB variable structure is  returned.  If  the  variable	was  not
     found, or there was an error reading the variable, NULL is returned.

EXAMPLES
     This  example  program  opens a MAT file named by the first argument to the
     program, and reads a variable named x from the file.   The  matio	function
     Mat_VarPrint is used to print the information and data from the file.

     #include "matio.h"

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

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

	 matvar = Mat_VarRead(matfp, "x");
	 if ( NULL != matvar ) {
	     Mat_VarPrint(matvar);
	     Mat_VarFree(matvar);
	 }

	 Mat_Close(matfp);
	 return EXIT_SUCCESS;
     }
