From: Anabel on 25 Jul 2010 12:24 Hi, Does anybody have any idea how to do this? I want to plot some contour lines over a 3D surface. I manage to plot several contour lines at the levels of z (z axis) that I want. But I can't do it for levels on the x or y axis. For example this prints the contour line at the z=0 level on my 3D surface _____________ hold on contour3 (x,y,z, [0 0]) hold off _____________ I want to plot also the contour line at x=0 and another one for y=0. Is this possible? Thanks |
