get average elapsed time

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.

It works! Thank you :)

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()
