Hi all. I've figured out how to get the average of multiple cell arrays so that the end product is a 1x22051 complex double. However, is there a code that could simplify this? I have over 50 cell arrays, but shortened it for this example.
avg_ydft = (ydft{1,1}+ydft{1,2}+ydft{1,3}+ydft{1,4}+ydft{1,5}+ydft{1,6}+ydft{1,7}+ydft{1,8})/8;

Assuming that each cell contains a 1x22051 vector (i.e. they are all the same size):
avg_ydft = mean(cat(3,ydft{:}),3)

I get the following error. How could I rewrite the code?
Error using var (line 197)
W must be a vector of nonnegative weights, or a scalar 0 or 1.
Thank you and best regards,
Christoph

I have asked the question separately (https://www.mathworks.com/matlabcentral/answers/864270-standard-deviation-of-multiple-cell-arrays).
This modified code also works for the standard deviation:
SD = std(cat(3,M{:}),[],3)
