Hi everybody,

i've a question about pause(n) where n is the time in seconds.

The fragment code where i've the problem is this:

tic
  while (~get(handles.pause,'Value')) %toc<=60 &&
      writePosition(s,maxTravel);
      pause(ts);   
      writePosition(s,INITPOS);
      pause(ts);
      cycle = cycle+1;
      cycleTotal(day+1) = cycle+1;
      [time,minutes,hours,day] = timerFun(minutes,hours,day,toc);
      set(handles.status,'String',time);
      pause(ttot);
  end

in fact i use the 'Value' of ToggleButton, named pause, to stop the while cycle, but the pause(ttot) varies (i.e. 1 second or 20 seconds), obviously if the waiting time is short the ToggleButton 'Value' is checked frequently, otherwise if the waiting time is long when i push the ToggleButton on the GUI i must wait the end of pause before the while-cycle 'Value' is invoked.

Is there a trick to stop pause() function or other method to check the ToggleButton 'Value' independently from pause function?

Sorry,

I've omitted pre and post code at cycle. This piece of code is into a GUI and user, through a text box, sets the delay and start the process with a button. As I said the delay varies and thus the togglebutton check is slow if the pause(ttot) is long. If ttot=20, for example and I press togglebutton when the pause is just started I must wait 20 seconds before the check happen, therefore I'm interested to know if there's a way to stop the pause function or to make a togglebutton check in other manner.

Hi，

I am confronted with this problem now. When I quit GUI, the pause function is still working. I am wondering if there is any method to terminate it when the GUI is close(except ctrl+c)?

Thanks in advance
