Hello,
I have a matrix of (n*72), and due to too much noise, I have to use smooth( moving average). Moving average has to applied to each column (from 1:72) and not rows. n is no. of experiments( =5) and sensors are 72. so matrix is (5*72),so smooth has to be applied to each sensor. How should I do it? Kindly help.

You can use the movmean function and set the dim property accordingly to get the moving average. You can also look at the smoothData function which is similar but the window length is chosen heuristically.

Let A - your data (N x 72);
out = conv2(A,ones(5,1)/5,'valid');
