In this example, your code is executed on each iteration and the while-loop waits for the remaining time to pass before entering the next iteration.
iterationTime = 2; %minimum number of seconds for each loop
for i = 1:10
tic; %set clock
fprintf('iteration %d\n', i) % <-- your code goes here
while toc < iterationTime %wait for the remaining iteration time
% do nothing %leave this empty
end
end
