Making Matrix dimensions agree

I'm attempting to make a surface plot using 101 and 201 data point for the x and y respectively. I've attempted changing the fxy but am having no luck making the dimensions agree. This is what I have below so far. Thank you in advance to anyone that can help.

x=-2:0.04:2;

y=-4:0.04:4;

[X,Y] = meshgrid(x,y);

fxy= x.*exp((-x.^2)-(y./2).^2);

surf(X,Y,fxy)

x=-2:0.04:2;
y=-4:0.04:4;
[X,Y] = meshgrid(x,y);
fXY = X.*exp((-X.^2)-(Y./2).^2); % use X and Y here, not x and y.
surf(X,Y,fXY)
