contourz

3D contour plot on a surface.

Description

Similar to contour3 but contours are drawn over any surface.

This may be useful if you wanna add contours to a surface created by surf(x,y,z,v).

Notice that if v = z, is the same as use contour3.

The screenshot was created as:

[x,y,v] = peaks;
z=-(x.^2+y.^2);
       surf(x,y,z,'facecolor','none','edgealpha',.1)
hold on
contourz(x,y,z,v);

% add clabels:
view(2)
contourz('clabel');
view(3)

• MATLAB release: MATLAB 6.0 (R12)

Works and follows a gap in Mathworks contour functions. Much apreciated!
