MATLAB: How to save the MATLAB desktop state without exiting

MATLAB

I would like to know if there is a way of having the MATLAB desktop save its state without exiting. I would like to save the list of open files, screen position, etc, the things it usually saves when you exit, without actually exiting. My MATLAB is crashing a lot lately, and when it crashes, the Editor state does not get saved. When I start it up again, it has the same state as the end of the previous session. I would like to be able have an option to save without needing to quit and restart.

This enhancement has been incorporated in Release 2008a (R2008a). For previous product releases, read below for any possible workarounds:

As a workaround, you can try a utility function named EXMANAGER from the MATLAB Central File Exchange. It is useful for saving workspace, figures and diary. You can find it at the following URL:

MATLAB: Do I receive an error when trying to import a MAT file in MATLAB 7.0 (R14)

This bug has been fixed in Release 2006a (R2006a). For previous product releases, read below for any possible workarounds:

This bug has been fixed for Release 14 SP1 (R14SP1). For previous releases, please read below for any possible workarounds:

This has been verified as a bug in MATLAB 7.0 (R14) in the way that it handles the loading of MAT files.

Currently to work around this issue, use the '-v6' option to save the MAT file in a MATLAB 6.5 (R13) compatible version:

v6file='original';
v7file='new';
load(v6file);
save(v7file,'a','b','c','d','-v6'); 
% The following line should be executed from MATLAB 6.5 (R13)
load(v7file)

MATLAB: How to prevent the error dialog from blocking a compiled standalone application from exiting

There are two solutions for this: Either enable displaying to the shell or catch the exception and terminate the program.

When the "Do not display the Windows Command Shell (console) for execution" check box under "Additional runtime settings" in the Application Compiler GUI is checked, or if you compile with "mcc" using "-e" (or "-W WinMain -T link:exe"), then error messages will be rerouted to a dialog box. Enabling displaying to shell will display the error in the shell from which the program is run.

See the following documentation page for more information:

Alternatively, if you would like to terminate the application when there is an uncaught error only in the deployed application, then you can wrap your code in a try-catch block, and in the catch block, do any necessary logging and call quit/exit with the appropriate exit code after checking if the script is deployed:

try
    myProgramScript;
catch E
    % do something with caught exception
    if isdeployed 
        quit(-1)
    end
end
