How to plot projections of plot3(X,Y,Z) on same 3D graph

How can I plot on same 3D graph of plot3, the projections on XY and so on.

X Y Z are vectors similar to the matlab example http://www.mathworks.com/help/matlab/ref/plot3.html .

I would like the projections to be on the walls xy xz .. planes like shadows. Similar to what contour plot is doing for 3D surface plots.

Depending on how your X and Y are structured, you may wish to consider using meshc

Are the points in a rectangular grid or are they scattered?

[Walter Roberson]

I see that you adjusted the question to indicate the the inputs are vectors, presumably not happening to fall into a nice grid.

In such a case:

subplot(1,3,1);
plot3(X, Y, 0*Z);    %projection from Z+

subplot(1,3,2);
plot3(X, 0*Y, Z);    %projection from Y-

subplot(1,3,3);
plot3(0*X, Y, Z);    %projection from X+

I might have the "Y-" wrong.
