How can i extract a 2D plane out of 3D plot?

Hello

I want to extract a 2D-plane out of a 3D plot.

x = -a:1:a; y = x; z = f(x,y);

I plotted a 3D plot using mesh command. Now i need to capture a plane that is at x=0, all y points and all corresponding z points. What commands should i use to get that?

Thanks Sazzad
