Is it possible for me to run a loop for a specified amount of time say 3 seconds?

This isn't a for loop, but you can get something like what you describe using a while loop.

t = now;
secondsToWait = 3;
while true
   if now >= t + secondsToWait/24/60/60
      break;
   end
   % Here you can put what you want to run...
end

This isn't perfect because if you have something that takes a long time to run, it won't be stopped by the loop until after it is finished.

Also, if you use "now" then you are going to be referring to clock seconds rather than cpu seconds.
