Details:


In calling contour one can use the following forms



 -- contour (Z)
 -- contour (Z, VN)
 -- contour (X, Y, Z)
 -- contour (X, Y, Z, VN)
 -- contour (..., STYLE)
 -- contour (HAX, ...)
 -- [C, H] = contour (...)



the meaning of the input parameter called 'VN' above does not seem to be
described in the docstring.

by manual testing I think VN indicates the values of the isocurves to be
plotted if it is an array, while it indicates the number of equispaced
isocurves if it is a scalar.
