Hi,
I have a function [runx] with an output that is a 11x256 matrix.
I would like to run this function 500 times. And generate a matrix with all the elements' averages. Sum(x) adds the elements in the same matrix together. It's not what I want.
For example:
run #1: [1 3 5; 4 6 7], run #2: [0 0 0; 1 1 1], run #3: [3 4 6; 0 1 2]
The operation that I would like to do is:
first row is [ (1+0+3)/3 (3+0+4)/3 (5+0 +6)/3] second row is [ (4+1+0)/3 (6+1+1)/2 (7+1+2)/3]
Final result: [4/3 7/3 11/3; 5/3 8/3 10/3]
Please help. Thank you.

A long way about doing it, but I got it to work.
jj = 500; [wxgen]=runx;
m = wxgen;
for i=1:jj-1 [wxgen]=runx; m = m+wxgen; end
meantwxgen = l./jj

Since I want to generate my function 500 times, there will be five-hundred 11x256 matrices. Am I typing run1, run2,... run500? My run code so far is (wxgen is a 11x256 matrix output of my function runx).
for i = 1:500; [wxgen] = runx
???? end
