y = sum(x=='1');

Well, well! Here he/she is as well, great job continuing your copy and paste of the cheap and meaningless trick you prick!

In case you didn't know how to do it and wanted to know how -which somehow I doubt it for some reason!, but anyhow, here is one of MANY ways to do it:
function x=one(x),x=count(x,'1');end

y = length(find(x=='1'));
