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

nd = ndims(CC{1,1});
sol = sum(cat(ndims+1, CC{:,1}),ndims+1);
There are also approaches using the more obscure fold() operation.

for i=1:24
sol=sum((CC(:,i)))
end

No, not for a cell array. sum() does not apply to cell arrays.
Also, you are overwriting all of sol each iteration.
