control for-loop index using a gui slider

I'm on an older version of Matlab (2011a) and am trying to set up an interactive loop. I am for-looping through a time vector, and would like to control the index via a gui slider. How would you go about solving that? A play/stop function that works together with a plotting function. Most other questions on the topic relate to stopping loops using gui functions which isn't quite the idea here.

My first recommendation would be to use an infinite while loop. Fo starters, in pseudocode:

function StartButtonPressed
% this function executes when you hit the start button
% initialise things here
while true
   k = GetValueFromSlider ; % k = current time
   if k < MaxValue
      k = k + 1 ; % increment time
      % code to update plot here
      % code to set slider value to k 
   end
   if StopButtonPressed
       break
   end
end
% code to clean up things go here
