How can I project a 3-D surface onto an axis?

I would like to generate a projection of a surface on one axis. For example, I wish to see the x-z axis of a 3-D view of a surface. What MATLAB commands allow me to do this?

This bug has been fixed in Release 14 Service Pack 2 (R14SP2). For previous releases, please read below for any possible workarounds:

[X,Y] = meshgrid([-2:.2:2]);

Z = X.*exp(-X.^2-Y.^2);

surf(X,Y,Z,gradient(Z)) % An example of 3D plot

colorbar

xlabel('X-AXIS')

ylabel('Y-AXIS')

zlabel('Z-AXIS')

axis([-2 2 -2 3 -0.5 0.5]) % Increasing the Ymax value in the axis to 3.

SX=size(X);

Y3 = 3*ones(SX); % A projection along Y-axis by making all Y-values to 3.

hold on

surf(X,Y3,Z,gradient(Z))
