NAME

     Mat_VarReadInfo — Read the information for a specific variable in a MATLAB MAT file.

SYNOPSIS

     #include <matio.h>

     matvar_t *
     Mat_VarReadInfo(mat_t *mat, 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;
     }
