How can I eliminate this loop from my Matlab code?

Question

My goal is to reverse the order of the three matrices, by an order of magnitude two matrices just (with one line of code perhaps) Any idea?

A = rand(256, 256, 3);
B = zeros(256, 256);


for i = 1: size(A, 1)
    for j = 1 : size(A, 2)
        B(i,j) = max(A(i,j, :));
    end
end

I think this is what you need:

B = max(A, [], 3);
