NAME

       Mat_VarReadInfo — Reads the information for a specific variable in a MATLAB 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;
       }
