Hi,
you can use the Keypress-Function of a figure window.
Here's an example:
function testbreak
%
% Exits an infinite loop on keypress
%
f=figure();
pause(1); % to give the figure window time to open
running=true;
set(f, 'KeyPressFcn', @testend);
while(running)
fprintf('Running\n');
pause(0.0001);
end
function testend(src, event)
if(event.Character=='q')
running=false;
end
end
end
