Writing variables to a file, MATLAB in Mathematics

Assignment Help:

Writing variables to a File:

The save command is used to write variables to a file, or to append the variables to a MAT-file. By the default, save function writes to a MAT-file. It can either save the whole present workspace (all variables which have been generated), or a subset of the workspace (involving, for illustration, just 1 variable). The function save will save the file in the present directory, therefore it is important to set that properly first.

To save all the workspace variables in a file, the command is as shown below:

save filename

The .mat extension is automatically added to the filename. The contents of the file can be exhibited by using who with the -file qualifier:

who -file filename
