How can I label contour lines in meshc 3D-plot?

I have made a 3D-plot using meshc. I want to add labels to the contour lines. The handle return by the meshc is

h = 
  2x1 graphics array:

    Surface
    Contour

So I have tried to edit the properties using following command but it didn't work.

 h.ShowText='on';

What is the right way to do it? Thanks

I used the following code to adjust the height of contour plot above/below the mesh plot and adding labels to contour plot.

h=meshc(peaks)
hContour=h(2);
hContour.ContourZLevel=-15; %Default (-10)
hContour.ShowText='on'; %Default ('off')
hContour.LevelStep=2.5; %Default (2.0)

I would use a separate call to contour. You may have to experiment with the approach in Yair Altman’s Undocumented MATLAB article Customizing contour plots part 2 to put the contour plot on the same plane as the contours drawn by the meshc function.

When you get your code working, consider generalising your code to a function and then contribute it to the File Exchange. It seems useful.
