Can I stop MATLAB when it's being busy?

If MATLAB runs a code, and takes not responding (displaying 'Busy' at the lower bar, next to start button), it removes the - >> sign from the command window, and I cant do anything but close it from the windows's task manager.
Is there a more elegant approach to that problem?

Sometimes even Ctrl-C does not work, when Matlab has no chance to evaluate the events. Therefore a DRAWNOW can be helpful in longer loops. Even in Mex files this can be done using mexCallMATLAB.

In iOS even if I close and start the app sometimes it’s a never ending story. For example if there’s some code using input() if something other than numeric is given it stays forever unless I give in a proper value, wasted a lot of time figuring out , how to stop it.

Come on! Why dont you just talk to Matlab and indicate it to stop?

This is one of the major flaws of MATLAB. Although Ctrl+C "sometimes" works, the very fact that it doesn't "always" work makes it a major blunder on behalf of mathworks. The absurd yet only solution in these situations is to close down MATLAB and launch it again.

A major cause, especially on Windows, that control-C can have no effect, is in the case where more RAM has been requested than is physically present, and the operating system is busy swapping to and from disk. I am not aware of any comoperating system that does a good job of interrupt handling in that situation; it seems to me that Windows is poor on this regard. This is an operating system matter, though, not a MATLAB matter.

I usually press ctrl+c or ctrl+d.
I don't know how I get the idea of pressing ctrl+d but I remembered it worked sometimes. Here is a reference to the MATLAB documentation.
Stopping Execution
To stop execution of whatever is currently running, press Ctrl+C or Ctrl+Break. On Apple Macintosh platforms, you can also use Command+. (the Command key and the period key) to stop the program. For certain operations, stopping the program might generate errors in the Command Window.
For files that run a long time, or that call built-ins or MEX-files that run a long time, Ctrl+C does not always effectively stop execution. Typically, this happens on Microsoft Windows platforms rather than UNIX[1] platforms. If you experience this problem, help MATLAB break execution by including a drawnow, pause, or getframe function in your file, for example, within a large loop. Note that Ctrl+C might be less responsive if you start MATLAB with the -nodesktop option.

Thanks Fangjun Jiang, control+break definitly works, even in worst situation. My MATLAB was struck in a never ending plot loop, still it worked by pressing control+break.

You should press ctrl+c in such scenarios.
MATLAB will stop all excecution.

control+c will not alway stop immediately. In fact, it can take a number of hours before it stops in some cases.
