Add contour labels to a contour plot.
CLABEL(CS) adds height labels to the current contour plot
using the contour structure CS output from the CONTOUR routine.
The label positions are selected randomly. For example:
cs = contour(rand(10)); clabel(cs)
CLABEL(CS,V) labels just those contour levels given in
vector V. The default action is to label all known contours.
CLABEL(CS,'manual') places contour labels at the locations
clicked on with a mouse. Pressing the return key terminates
labeling. Use the space bar to enter contours and the arrow
keys to move the crosshair if no mouse is available.
