get average elapsed time
显示 更早的评论
Hi. I have probability p in the code, so everytime I run it, different ans and elapsed time are obtained. I want to run the code for 100 times and get the avg ans and elapsed time. Do you know how to get these?

No idea what you are asking. Please upload the code so we can assist further.

clc; clear all;
N = 100 ; % number of time you run the code
elapsed_time = zeros(N,1) ; % initilaize the elapsed times
result = zeros(N,1) ; % initilaize the result for every run
for i = 1:N % loop for each run
t = tic ; % to get time evaluated
% do waht you want
K = rand(i) ;
thenorm = norm(K) ;
t = toc(t) ; % get time elapsed
result(i) = thenorm ; % store your result for final average
elapsed_time(i) = t ; % store the time elapsed for the run
end
% get avarages
result_avg = mean(result) ;
time_avg = mean(elapsed_time) ;
I have calculated the norm of a random matrix here, in place of that you call your probability code.

If you are interested in measuring average performance of your routine (rather than being interested in the average time to produce that specific set of values), then see timeit()
