MATLAB: Adding cell array entries

Question

Suppose you have a 162*24 cell array called CC and each cell array entry consist of a matrix.

How would you add CC{1,1}+CC{2,1}+CC {3,1}…..CC{162,1}

and then to the same for the remaining 23 columns.

I dont need the sum but all matrices within each cell entry have to be added.

Thanks

Answer 1

nd = ndims(CC{1,1});
sol = sum(cat(ndims+1, CC{:,1}),ndims+1);

There are also approaches using the more obscure fold() operation.
