I want to sum the subtraction of every element in a cell (1 column, "i" rows) with the others. Then, I want to sum all results

 elementos_cons1(all(cellfun(@isempty,elementos_cons1),2), : ) = [];
 B=cell(size(elementos_cons1));
 C=cell(size(elementos_cons1));
 D=cell(size(elementos_cons1));

 for k=1:i
    A=elementos_cons1{k};
    for j=1:i
        B{j}=A-elementos_cons1{j};
    end
    C{k}=cellfun(@sum, B,'UniformOutput', false);
    D{k}=cellfun(@sum, C{k},'UniformOutput', false);
 end

C is giving me what I want: its a cell with 1 column and "i" rows, and in each row there is another cell with "i" rows that have the result for the previous loop. Now, I want to add all the results from C. Instead, D is being the same as C; I want that, for every row, there is sum result of every cell from C. What is wrong?!

Answer 1

[Walter Roberson]

    D{k} = sum(C{k}, 2);

perhaps. This would be the row sum.

[Eduardo Rocha]

It says "Undefined function 'sum' for input arguments of type 'cell'." I used

 D{k} = sum(cell2mat(C{k}), 2);

but D is being the same as C again.
