quit (MATLAB Function Reference)

quit	Examples See Also

Terminate MATLAB

Syntax

quit
quit cancel
quit force

Description

quit

terminates MATLAB after running finish.m, if finish.m exists. The workspace is not automatically saved by quit. To save the workspace or perform other actions when quitting, create a finish.m file to perform those actions. If an error occurs while finish.m is running, quit is canceled so that you can correct your finish.m file without losing your workspace.

quit cancel

is for use in finish.m and cancels quitting. It has no effect anywhere else.

quit force

bypasses finish.m and terminates MATLAB. Use this to override finish.m, for example, if an errant finish.m will not let you quit.

Remarks

When using Handle Graphics in finish.m, use uiwait, waitfor, or drawnow so that figures are visible. See the reference pages for these commands for more information.

Examples

Two sample finish.m files are included with MATLAB. Use them to help you create your own finish.m, or rename one of the files to finish.m to use it.

finishsav.m - saves the workspace to a MAT-file when MATLAB quits

finishdlg.m - displays a dialog allowing you to cancel quitting; it uses quit cancel and contains the following code.

button = questdlg('Ready to quit?', ...
                            'Exit Dialog','Yes','No','No');
switch button
            case 'Yes',
              disp('Exiting MATLAB');
              %Save variables to matlab.mat
              save
            case 'No',
              quit cancel;
end
