stugeling with if statement displaying results

I am trying to write a file to simulate a roulette game, I am up to the if statement and trying to get matlab to display either green,red,or black for a random spin of the roulette table. it will display green as i used an if statement for that but it wont display red or black...i think it has something to do with the way i entered the numbers... this is how i have set out the file....

%% Roulette simulation clear, clc x = randi([0,36]) if x==0 disp('green') elseif x==[1,3,5,7,9,12,14,16,18,19,21,23,25,27,30,32,34,36] disp('red') elseif x==[2,4,6,8,10,11,13,15,17,20,22,24,26,28,29,31,33,35] disp('black') end

You are correct. It is how you compare x. The result will be a vector containing lots of false and maybe one true. If you change it to ;

elseif any(x==[1,3,5,7,9,12,14,16,18,19,21,23,25,27,30,32,34,36])

It will work.
