How to delete a file when closing Matlab?

I cerated a .mat file with a variable inside that serves as a sort of memory. I need to delete this file when closing Matlab or when I reopen Matlab. How can I do that? If I store the file in the temp folder of Matlab, it will be deleted every time I close Matlab or not?

Use delete command the mat file called DONE.mat, e.g.:

delete('DONE.mat')  % e.g.

One good option is to edit startup.m file

% Add the Path to the DONE.mat file that you want to delete
File_2_Delete = 'C:/Windows/Temp/DONE.mat';

% Check if the file exists
if exist(File_2_Delete , 'file') == 2
    % Delete the file
    delete(File_2_Delete);
    disp(['File ', File_2_Delete, ' deleted at the MATLAB start!']);
else
    disp(['File ', File_2_Delete, ' does not exist!']);
end

All the best.

Similar to a startup script, you can also create a finish script that would run while closing matlab, here is documentation for it. You can add a delete if exist command in both finish and startup scripts :)
