% Runs for 5 seconds (i.e., 5/60 minutes)
T = 5/60; % minutes
ti = datetime('now');
tf = datetime('now');
while (minutes(tf-ti) < T)
    % Do stuff

    % Update current time
    tf = datetime('now');
end
seconds(tf-ti) % Should be the same as T (in seconds), or

ans = 5.0000

minutes(tf-ti) % Should be the same as T (in minutes)

ans = 0.0833

But you can't rely on this for precise timing.

execusme sir, do you have any idea how i can computer the elapsed time in each iteration in for loop ?

You can use the tic/toc commands within the while loop:

tic
% Do stuff

elapsedTime = toc

elapsedTime = 0.0036
