Koustubh - please provide some context. Are you starting a script from a GUI control callback function? Is this really a script or a function? What does it do? And why do you want to stop script from your GUI rather than letting it complete?

Hi Goeff,
Thanks for the reply. Its a script. In that script I have written guicontrol function for pushbutton. If I press the button, the button name is 'Stope' which should ideallly stop the script to run further(In this case user wants to end up the script since he is satisfied with the reults). I hope this will helpufl you to understand the scenario which I want to implement.
please let me know if u need more info.
Regards,
Koustubh

You have four options to stop a script without its cooperation:
1) you can quit() MATLAB. Note that if you do this then onCleanup will still run and you will be asked about saving any changes in the editor
2) you can use Java Robot class to issue control C to the command line. In this particular context it should stop immediately (except perhaps some onCleanup) but in general control c can take hours before the command line gets control
3) you can force an out of memory error
4) you can force infinite recursion. MATLAB will notice and stop the program.
If you want a smooth termination of whatever is running then the only way to achieve that is with the cooperation of the program, with it having to check to see if stop was requested and deliberately ending computations early.
