The matdgns.c example illustrates how to use the library routines to read and diagnose a MAT-file.
in_file){perror("fopen");exit(EXIT_FAILURE);}structstat sb;if(stat(filename,&sb)==-1){perror("stat");exit(EXIT_FAILURE);}char*file_contents=malloc(sb.st_size);fread(file_contents,sb.st_size,1,in_file);printf("read data: %s\n",file_contents);fclose(in_file);free(file_contents...
