Select the Confirm before exiting MATLAB check box and click OK.
MATLAB then displays the following dialog box when you exit.
You can also display your own exit confirmation dialog box using a finish.m script, as described in the following section.
When MATLAB exits, it runs the script finish.m, if finish.m exists in the current folder or anywhere on the search path. You create the file finish.m containing statements such as saving the workspace or displaying a confirmation dialog box. There are two sample files in matlabroot/toolbox/local that you can use as the basis for your own finish.m file:
finishsav.m — Includes a save function so the workspace is saved to a MAT-file.
finishdlg.m — Displays a confirmation dialog box that allows you to cancel quitting.
