Stop a infinite while loop pressing a key in Matlab

I have a while loop, infinite, and I want to stop it when I press a keyboard key.

Pseudocode:

While(1)
    do stuff;

    listening for key;
    if key is pressed
        break;
    end
end

The function waitforbuttonpress makes me press the key, so no luck.

I've found no option on the web.

Solution

  • I suppose if you don't want to resort to multithreading (one thread doing the computation in the while loop, another one waiting for input and setting a global sentinel value to break the while loop) you can try to implement breaking the loop on catching a keyboard-interrupt (ctrl-c). This should be possible, albeit in a kinda hackish way.
