In this Ex. i want all the functions under r loop to run for each r iteration (taken one at a time till rmax) with specific execution time not the iteration time for the whole r loop. I mean say r=3, if all operation under iteration r=3 should run for 0.5sec then how should i o for it. Thanks in advance.
Ex: rmax=1000
n=100
for r=0:1:rmax
(some operation)
for i=1:1:n
(some operation)
if (some condition)
end
end
end

@kalyan I want to make the execution time (round time in my program) of each r iteration value according to my desire seconds so that the operation under r loop can be operated for that round time only for each r iteration.
say ex: if r=2 the execution time is 0.24 sec to perform the operation under this loop. is there any option to change the exceution time of each r?

TT = tic;
while toc(TT) < timelimit
do more of the calculation
end

It depends on how accurate you need the timing to be. If you have
TT = tic;
while toc(TT) < timelimit
for K = 1 : r
do more of the calculation
end
end
then the time spent in the for loop would be r times how long it takes to do each iteration, and that would determine how often toc was checked. Typically larger r would be more efficient but would lead to toc being checked less often.

If you want to change the execution time for the iterations, you can look for indexing (avoid loop if possible) or use the functions and call in the current scripts.
