Adding multiple rows of a cell array

D = load('NumericalFourierForce.mat');
Numerical_FourierForce = D.Numerical_FourierForce;
Out = cellfun(@(x){sum(x(1:2:end,:)); sum(x(2:2:end,:))}, Numerical_FourierForce, 'Uni',0);
Out{1}{1,:}                                                                                   % Check Output
Out{1}(2,:)                                                                                   % Check Output
Out{5}{1,:}                                                                                   % Check Output
Out{5}(2,:)                                                                                   % Check Output

Notice that there are no explicit loops. (There are obviously loops within cellfun.)

Edit: cellfun() is a loop in disguise by the way.

 for k = 1:numel(cell_array)
     cell_array{k}(end+1,:) = sum(cell_array{k}(1:2:5,:));
     cell_array{k}(end+1,:) = sum(cell_array{k}(2:2:6,:));
 end
