force stop condition in a loop

can i add a condition in a loop that identify force stop (ctr+c) ? for example i control with matlab in a current source in a infinite loop (while(1)), and i want it to turn off when i stoped the loop with ctr+c for example: if force stop fprintf(device, ':OUTP OFF'); end

You can use onCleanup.Minimal exampel:

mytest()
function mytest()
finishup = onCleanup(@() mycleanup());
myloop();
end

function myloop()
  while true
    disp('running')
    pause(1)
  end
end

function mycleanup()
disp('stopped')
end

However maybe a loop that runs until a specific button is pressed is a cleaner approach.

i know break, how it can help me? i want a way the code to identify force break and to do something when it happens

Whats the criteria for force stop?

[liran avraham]

the loop is some homemade temperature control, that why the loop is infinite, so i force break when i want to change the temperature or to stop measuring.
