Such a file is fully portable to matlab running onanother kind of computer. Information about the kind of computer thatmatlab was running on when it saved the data is stored along with thedata. When matlab reads in a mat-file, it checks the type of computerthat the data were saved on and automatically performs any requiredmanipulations (byte swapping, for example).To load data from mat-files use the load command:>> clear>> a = 1;>> b = 1:10;>> str = ’hello’;>> save saved_data>> clear>> whos>> load saved_datac○ 2000 by CRC Press LLC
