MATLAB: Labeling only specific contour lines in a contour plot

I have a contour plot with many lines. However, I want to label only some of those lines. How do I do this?

Best Answer

For labeling only some of the lines in a contour plot, define a vector with the lines you want to label, and give that as an input argument to the "clabel" function. 
As an example : 
 
% Generate labels only for contour lines 2 and 6
[x,y,z] = peaks;
[C,h] = contour(x,y,z);
v = [2,6];
clabel(C,h,v);
