MATLAB: How to do running mean

Question

Hi all,

I have a 3d matrix with a dimension of 21*41*273, for which I want to do the running mean over the third dimension (273 days) for every 4 days.

Any help would be appreciated.

Answer 1

Try something like this

M = rand(21, 41, 273);
M_new = movmean(M, [0 3], 3, 'Endpoints', 'discard');
M_new = M_new(:,:,1:4:end);
