Plot f(x,y) = sin(2piX)sin(2piY)

So I'm attempting to plot the function f(x,y) = sin(2*pi*X)*sin(2*pi*Y) on the interval [-2,2]x[-2,2], but I'm getting an odd looking graph. So far my code looks like this:
x = -2:.1:2
y = -2:.1:2
[X,Y] = meshgrid(x,y)
Z = sin(2*pi*X)*sin(2*pi*Y)
surf(X,Y,Z)
For some reason, it's only returning a Z value of 20. Any ideas?

Hi William,
Try this:
x = -2:.1:2
y = -2:.1:2
[X,Y] = meshgrid(x,y)
Z = sin(2*pi*X).*sin(2*pi*Y) % Peform element wise multiplication
surf(X,Y,Z)
Hope this helps.
Regards,
Sriram
