Mean matrix of different size matrices in one cell array

Hi, everybody!

I have different size 3D matrices in 1x5 cell array, like this :

A = {{9×119×11},{6×119×11},{8×119×11},{9×119×11},{7×119×11}}

How to find one mean matrix across all matrices?

Thanks so much in advance for your help!

What size is the expected output array?

[IM]

Expected output must be only one 3D matrix ,like this : X×119×11.

"Expected output must be only one 3D matrix ,like this : X×119×11"

And what is X for your given example?

Answer 1

[Stephen23]

C = cellfun(@(m)mean(m,1),A, 'uni',0);
B = cat(1,C{:})
