How to eliminate this loop from my Matlab code?

Question

My goal is to change an order three matrix, to an order two matrix simply (perhaps with one line of code) 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

Answer 1

我认为这就是你所追求的：

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