MATLAB Function Reference

quit

Terminate MATLAB

Graphical Interface

As an alternative to the quit function, use the close box or select Exit MATLAB from the File menu in the MATLAB desktop.

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 functions 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
