[Pkg-octave-devel] Bug#492042: octave3.0: contour sometimes plots two lines less

[Francesco Potorti`]

Package: octave3.0
Version: 1:3.0.1-4
Severity: normal

When giving a vector of line levels to plot, contour plots two lines less.
For example, these two commands create the same plot:

x=1:10;y=x;z=vander(x);contour(x,y,z,5)
x=1:10;y=x;z=vander(x);contour(x,y,z,linspace(1,1e9,7))

Note that in the second command, one has to ask for seven lines in order
to get 5.
