MATLAB: Drawing a 3-D graph, endpoint issues

3dgraph

Hello everyone,
I asked a question similar to this under the subject of linspace but I am re-posting it because this time I wanted to attach the photos. So that you can see clearly what my issue is.
The black/white graph(3dd.jpg) is what I am trying to draw and the graph in color(3d.jpg) is what I have drawn. I am not sure what I must modify to be able to successfully draw the black/white graph(3dd.jpg). I tried modifying the linspace values but I still couldn't achieve my goal.
Following is my code,
x=linspace(-2,2); 
y=linspace(-2,2); 
[X,Y] = meshgrid(x,y); 
Z=(X.^2+3*Y.^2)*exp(-X.^2-Y.^2); 
meshz(X,Y,Z)
Thank you very much.

Please clarify what you want.
This code:
x=linspace(-2,2); 
y=linspace(-2,2); 
[X,Y] = meshgrid(x,y); 
Z=(X.^2+3*Y.^2).*exp(-X.^2-Y.^2); 
meshz(X,Y,Z)
produces this plot:
