I have a 25x5 cell called Data, each with a 15x3 double. What I would like is to calculate are:
nanmean(Data{1:25,1}(:,3)),
nanmean(Data{1:25,2}(:,3)),
nanmean(Data{1:25,3}(:,3)),
nanmean(Data{1:25,4}(:,3)),
nanmean(Data{1:25,5}(:,3)).
So, basically to calculate the mean value of the third column of the doubles for every column of the cell, thus generating 5 mean value in total. I've already tried it with
nanmean(cellfun(@(x) mean(x(:,3)), Data))
but this doesn't calculate the mean values I'm looking for.
Any help would be appreciated!

"doesn't calculate the mean values I'm looking for" &nbsp I think that it indeed calculates the values you describe in the question. Nevermind mean instead of nanmean
You might want to give us a small numerical example.

Thank you. I've checked it once again and noticed, that it works correctly. The command history showed me that I made an mistake yesterday when checking the command.
