Hi!
I have a 61x2x1000 double which gives me the results of 1000 simulations for stock prices of 61 consecutive months. This is for two different stocks, why the third dimension here is 2.
How do I get to the average stock price of one stock for each month? Or let's say the average for every second month price for stock 1 of all the 1000 trials?
Thanks!

Average price of stock each month.
stockA=zeros(1,61);
stockB=zeros(1,61);
for k=1:61
stockA(k)=mean(yourMatrix(k,1,:));
stockB(k)=mean(yourMatrix(k,2,:));
end
