Hi all,
I have multiple 3D matrices with the dimension of 21*41*24 for each which 24 (third dimension) is 24 hours.
I wanted to calculate 6 hours average for the third dimension.
Where I am mistaken?
NHours=size(ucom,3);
NDays=NHours/6;
out = nanmean(permute(reshape(ucom,[6,NDays]),[2,1,3]),3);

Taking a slightly shorter example, try something like this —
% ucom = randi(9,21,41,24);
ucom = randi(9, 3, 4, 24);
sz_ucom = size(ucom);
ucomr = reshape(ucom,sz_ucom(1),sz_ucom(2),[],6);
out = nanmean(ucomr,4)
The ‘out’ variable now has 4 blocks of 6-hour averages

As always, my pleasure!
(Sorry for the delay — I was off doing other things.)
