Try this

X=[-4 -1 0 2 10];
Y=[-5 -2 2 5 9];
[~,idx] = find(X>Y);

If the scale of X and Y is the same, you could use a "for" loop to go through every element.

for i=1:numel(X)
   if X(i) > Y(i)
      % Do something
   end
end

or you could use the function "gt"

type "help gt" in matlab without quotes for more details
