How can I get MATLAB to leave a loop when any key is pressed?

I have a MATLAB script that contains a(n endless) loop. I want the loop to be exited when a key is pressed?

This is a bit of a hack, and will probably slow down your code. The idea is to create a figure, and check whether a key has been pressed when the figure is active. Ergo, you need to click on the figure window and press a key while the cursor is over it.

WARNING: The following is an infinite loop. Use ctrl+c to break it if problems arise.

 h = figure(1);
 forever = 1; 
 while forever 
     drawnow
     isKeyPressed = ~isempty(get(h,'CurrentCharacter'));
     if isKeyPressed
         break
     end
 end
