Hi,

I'm trying to find the average values inside a matrix, [N 1]. I'm using N simulations and for each simulation I get a value. What I want to do is to find the average value of G after each simulation of N and sample these results in a new matrix.

My script:

clc; clear all; close all;
N = 10;
x = 5;
G = zeros(N,1);
for i = 1:N;
     j = i*x; 
     G(i) = j; 
  end

Best regards

There is no Monte Carlo concept at all in that script. Anyway, to find the mean value of G after each run of N iterations, just put this line after the loop:

meanG = mean(G);

If you want the means at the end of each i'th iteration, then put this inside the loop, just after you assign G:

meanG(i) = mean(G);

It just depends on where you want to take the mean.
