MAT_VARREADINFO(3) FreeBSD Library Functions Manual MAT_VARREADINFO(3)

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

#include <matio.h>
matvar_t *
Mat_VarReadInfo(mat_t *matfp, const char *name);

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

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.

#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; 
}
