NAME
     Mat_VarReadInfo  -- Reads the information for a specific variable in a MAT-
     LAB MAT file.

SYNOPSIS
     #include <matio.h>

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

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

RETURN VALUES
     If  the  variable	was  found in the MAT file and the information about the
     variable 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 information, NULL is returned.

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

	 Mat_Close(matfp);
	 return EXIT_SUCCESS;
     }
