Hi everybody. I have a matrix array (2dimensional) and I would like to compute the mean of each coulumn.

R{i,j}=cell array with 186*157 size. i=1:186,j=1:157.

What is the contents of the cell elements? Do you want to get the mean value of the elements, or between the elements?

Try something like this —

R = {rand(10,8)}
R = 1×1 cell array
    {10×8 double}
Rmeanc = cellfun(@mean,R, 'Unif',0)
Rmeanc = 1×1 cell array
    {[0.4739 0.5144 0.6163 0.5387 0.4090 0.5248 0.3688 0.3456]}
Rmeanv = Rmeanc{:}
Rmeanv = 1×8
    0.4739    0.5144    0.6163    0.5387    0.4090    0.5248    0.3688    0.3456
