Run a loop every hour regardless of its calculation time!

Hi All

I want to run a look evey hour and do some math inside the loop.

one solusion is to use tic/toc to get the math time and deduce it from the pause time, but I find it not efficient.

Any solusion to this?

Thanks.

Using tic / toc in a while loop is not very efficient.

Much better to use a timer object.

while true
   tic
   % some math here  
   elapsedTime=toc  
   pause(3600+elapsedTime); 
   clearvars elapsedTime;
end
% Please note on while loop to avoid infinite run

Thanks for your answer. The problem with this solusion is that elapsedTime will not be reset in every loop and incread each loop!

Thats why I have added the following line in the code, now every time it clear the privious elapsedTime.

clearvars elapsedTime;

Hope it helps!

I would expect 3600-elapsedTime not 3600+elapsedTime

Use timer is much better. I think PAUSE will lock completely 99% of MATLAB.
