// NOTE: the previous contour code line should read:
contour(X,Y,Z,[Zc Zc],flag=[0 0 4]);
Right.
When Zc is not a strictly positive integer, it should be taken as a
single Z level.
But it is currently not the case. It is a bug :
http://bugzilla.scilab.org/13467
Then, for plotting the only level z=0, specifying 1e-300 would be OK
And for plotting the only level z=2, 2*(1+%eps) would do it.
Doubling [Zc Zc] is another trick. contour() does not apply unique() on
specified levels,
and so processes the same level twice. Another improvement to implement.
