How to graph the projections of some surface on the XZ and YZ planes using plot3()

I've already attempted to do this and was wondering if someone could help me with my code:

function[]=plot10() x=linspace(-pi,pi) y=linspace(-pi,0) y2=zeros(100) x2=zeros(100) [X,Y]=meshgrid(x,y) Z=sin(X).*cos(Y) surf(Z) title('Z = sin(x).*cos(y)') xlabel('X') ylabel('Y') zlabel('Z') hold on plot3(X,y2,Z) plot3(x2,Y,Z) hold off
