I've just started using Matlab, I previously got this to work, but for some reason I can't figure out why it's not working any more. Anyway, it's just a mess around.
question = input('say friend and enter');
str = 'correct';
message = [str];
if (quesition ~= friend);
disp(message)
end

It's fine now, I didn't account for the fact that I used letters instead of numbers, so:
question = input('say friend and enter ', 's'); str = 'correct'; message = [str]; if (quesition ~= 'friend'); disp(message) end
