MATLAB: Extract Plot3 intersection with y=0 plane

intersectionMATLABplot3

Hi, I have a problem with intersection between a plot3 and a plane.
I have this plot3 from three array (along three dimension), but I have to cut this plot with Y=0 plane and visualize the intersection (in a X-Z plane), thus I have to fit this curve resulting from the intersection.
Can you help me?
Thanks a lot in advance.

If the curve and plane have only one intersection you can use this simple script:
    % generate some data
y = linspace(0,10,30);
x = sin(y);
z = y;
    % Y plane at y=3
y0 = 3;
x0 = interp1(y,x,y0);
z0 = interp1(y,z,y0);
plot3(x,y,z)
hold on
plot3(x0,y0,z0,'or')
hold off
