Hi everyone. I need some help to code this problem:
The data is 480x10 matrix(ret). I want to calculate the mean of each column from the past 120 elements of the same column
m1=mean(ret(1:120,1:10))
m2=mean(ret(2:121,1:10))
...
m360=mean(ret(360:480,1:10))
How can i do it with a loop and receive the results in a matrix 360x10.

I think you mean,
m360=mean(ret(360:479,1:10))
m361=mean(ret(361:480,1:10))

m=conv2(ret,ones(120,1)/120,'valid')
