can anyone help me to sort out the problem here

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

Sorry the questions is not clear for me.

@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

+1 Great Sir

@walter roberson thanks Sir. it works for what i want in the execution time of each iteration but Sir i want to ask one more question. will it be necessary to change the inner loop operation condition also which is dependent on r value if i increase or decrease the time?

[Walter Roberson]

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.

@walter thanks a load Sir. Your information really helps a lot.

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.
