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

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

       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;
       }

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

       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.
