Hi
I have a vector that I want to find the average over each 3 numbers. So if I have a vector A and sampling it over 3 I would get new_A. However my solution isn't working. Could you help me?
A = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15]; %The vector
count = 1;
for i = 1:3:length(A)
new_A(count) = mean(A(i:i+1));
count = count+1;
end
new_A = [2 5 8 11 14]; %The desired ouput

Sliding window or each distinct group of 3? If it is each distinct group of 3, then reshaping to 3 x something and then mean() along the dimension you made 3.
