30 Saving and Loading Data

30.1 MATLAB Format

matlab’s internal standard for saving and loading data is the mat-file.
The save command saves all the variables in the workspace to a disk file
called matlab.mat:

>>a=1;
>> b = 1:10;
>> str = ’hello’;
>> save
Saving to: matlab.mat

To save in a file with a different name, type:
save saved_data
To save only some of the variables, add their names:

save saved_data a b

Mat-files are binary files whose format is described fully in the mat-
lab documentation. Such a file is fully portable to matlab running on
another kind of computer. Information about the kind of computer that
matlab was running on when it saved the data is stored along with the
data. When matlab reads in a mat-file, it checks the type of computer
that the data were saved on and automatically performs any required
manipulations (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_data
