This may be the list you want (all one one line if it gets cut up
here):
indices = [f.element.ambient_ray_indices() for l in L.level_sets()
[-3:-2] for f in l]
And by "address individually" do you mean indices[0], indices[1], etc?

Greetings,
I'm running notebook mode, looking at acyclic directed graphs which
I'm forming from rational polygon fans -> cone_lattice() command ->
hasse_diagram() command. One of the things that would be very useful
would be a command to select only the elements on a specific level

I fix this, thanks by your time

Yes in console terminal, when i make this
p1 = plot(spline(pattersonCpb),
(__builtin__.max(pattersonCpb)[0],__builtin__.min(pattersonCpb)[0]))+points(pattersonCpb)
show(p1)
the plot work fine, but when i make this load a extern file *.sage only i
get the points.

Exactly like you said. Make each plot:
plot1=plot(spline(pts), (0,5))
...
and then do
show(plot1+plot2+...)

We do get questions about "how to read matrix from csv" quite regularly. Of
course its just a few lines of code, but I think it would be nice to have a
matrix_from_file('fname.csv') function that imports csv and perhaps others
(gnumeric/ooffice/excel). Any volunteers? ;-)

uhm, i'm not sure if you ask about reading or writing. also, your "d" in

Justin,
I don't think that is the issue here: you are referring to the debate
between using a,2*b,c as coefficeints rather than a,b,c. But here
*all* the coefficients have been doubled.
Note that we also have

When I run:
sage: q = QuadraticForm(ZZ,2,[3,2,5])
sage: q.polynomial()
6*x0^2 + 4*x0*x1 + 10*x1^2
I would expect to get half of this result, which is the quadratic form
as a polynomial. The doc tests say this is what the behavior should
be, but I don't understand why. Is this actually the desir
Hi folks,
I am having trouble trying to save a matrix P as a CSV file in Sage:
Def function(A,D):
(sage syntax for creating a matrix P)
return P
and then using a function which opens up the CSV file and utilizes the
entires in the matrix P, from the CSV file.
Is there a method for this?
