Plot different colors

Question

Let\'s say W = [1 3 5; 2 1 5; 6 9 1] and K = [0.2, 0.5, 0.3] How can I plot all elements in k with the same color exept those elements that have

Answer 1

If you plot point-by-point you can change the color correspondingly, for example something like this:

for i = 1:size(W,2)
    if find(W>6)~=0
        plot(i,K(i),'xb');hold on
    else
        plot(i,K(i),'xr');hold on
    end
end

Since the information you gave is not enough, the code above needs to be modified according to W and K,....
