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?

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.

Someone owns you a 'Thank you', I guess.
