extracting a 2d plane from a 3d surface plot

Hi guys, sorry if this is an easy question but I'm new to matlab. I've done a surface plot with two 3-d planes in it. I have vectors x.dat and y.dat, and the 2 by 2 matrices z1.dat and z2.dat. I can plot both of these surfaces on one figure by
load x.dat
load y.dat
load z1.dat
load z2.dat
hold on;
surf(x,y,z1,'FaceColor',[1 0 0],...
'EdgeColor',[1 0 0]);
surf(x,y,z2,'FaceColor',[0 0 1],...
'EdgeColor',[0 0 1]);
hold off;
This plots z1 and z2 nicely in 3d space with one of them blue and the other red. What I'd like to do is plot the plane z=0, to show the intersection of z1 and z2 in the x-y plane at z=0. Is this possible to do with matlab? Thanks in advance for any suggestions.

How about
contour(x, y, z1-z2, [0 0])
?

Cool, sorry -- I read your question a bit fast! Glad you got it sorted

Plotting the plane is pretty easy
surf(x, y, zeros(size(x))
You can adjust colour, edgecolor, transparency etc if you want. Is that what you were after?
