I am trying to determine if all of the numbers in "x" is non-zero values:
x = [1 1 0]
% 1:
if x ~= [0 0 0]
disp('x is not zeros')
end
% 2:
if all(x ~= 0)
disp('x is not zeros')
end
but the output is saying the x is zeros.
what mistake did I make?

And why isn't this the expected answer? You are testing if all elements of Pref_Color are not equal to 0. Clearly this is false because the final element is 0 therefore it drops into your else block and reports 'no'.

Your second if statement is correct, and I get the correct output (none).
