Something like this? Anything suggestion that doesn't use tic-toc?

x=6;
if x>5
   tic;
   pause(5)
   if toc>4
       y=2
   end
end

What's wrong with tic and toc?

startTime = tic;
elapsedTime = toc(startTime);
loopCounter = 1;
while elaspedTime < 5
    fprintf('Iteration %d.\n', loopCounter)
    pause(0.4); % Waste some time.
    elapsedTime = toc(startTime);
end

I am planning to use the function in stateflow. I read somewhere (please don't ask me where, can't find it now) that tic-toc is not recommended with stateflow. So, that's why I thought maybe there is a more elegant way. But honestly, I didn't try it myself. Maybe it will work flawlessly.

I found timer function but it looks a bit too complicated.

Of course stateflow has its temporal logical operators as well. But I couldn't put my stateflow chart together in the way I want it. (And sorry, can't paste the whole project here obvisously. And yes, maybe I should re-consider my chart architecture.) This is my very first stateflow project, and the first matlab project after a looong time. I guess the best way is to try and see different methods.

Anyway, thanks for your time.

I have just tried tic-toc method. The problem is that tic-toc calculates the delay in real time. If I add a breakpoint to debug, then the elapsed time become very long. Need a solution with simulation time.
