Two very random thoughts: 1. You may also have a more global matplotlibrc file somewhere - that caused me no end of problems reviewing a patch once. 2. I'm not actually sure that matplotlibrc controls the colors of the lines in plots - this may be set by Sage itself directly.

Simon's solution looks like it would solve what I wanted at the time, but right now I think I will return to one file, debug everything (since things are still in a state of flux) then separate it into several files use a setup.py.

Sage doesn't actually use that file, as far as I know. Try putting a copy in $HOME/.sage/matplotlib-1.0.1/ (or a similarly named, already existing, directory). The reason that Sage doesn't use this file is that some matplotlib configuration files are not compatible among different versions of matplotlib, so Sage needs to make sure that it is accessing configuration files suitable for the version of matplotlib included with Sage.

Re: [sage-support] Re: Sums of Modular Symbols
Thanks for this. There still seems to be a manual step in going from,
say,
s1 = 2*(1,8) - (1,9)
to
s1 = 2*b[1] - b[2]
I may be misunderstanding you. Are you saying you want to enter the line
s1 = 2*(1,8)-(1,9)
verbatim and have it work? That I don't think I can do (unless you're
willing to type them not at the prompt but in a string or file which
is then parsed). One option is to use a dictionary as an intermediary
step:
age: M = ModularSymbols(11,2);M
Modular Symbols space of dimension 3 for Gamma_0(11) of weight 2 with
sign 0 over Rational Field
sage: m = dict((sage_eval(str(b)), b) for b in M.basis())
sage: m
{(1, 0): (1,0), (1, 8): (1,8), (1, 9): (1,9)}
This dictionary basically maps a tuple to the corresponding
ModularSymbolsElement in the basis. [Yes, to be safer I should really
use ast.literal_eval.] Then you could write:
sage: s = [2*m[1,8] - m[1,9],
: -m[(1,0)] + m[(1,9)],
: -m[(1,0)] + m[(1,8)]]
sage: s
[2*(1,8) - (1,9), -(1,0) + (1,9), -(1,0) + (1,8)]
Note that the parentheses () are optional. Finally:
sage: V = span([sx.list() for sx in s],QQ)
sage: V
Vector space of degree 3 and dimension 3 over Rational Field
Basis matrix:
[1 0 0]
[0 1 0]
[0 0 1]
Would something like that work or do you have a particular format that
you can't escape?

[sage-support] Use latex tags in variable names?
Hi,
I just started using Sage, and I have a question about variable names.
I skimmed through the documentation but could not find any answers.
Is it possible to used latex tags in variable names so when I do
show(var) I get the latex output?
For example, I want to do:
p_1star = var('p_1^*')
but apparently it does not work. (latex(p_1star) yields p_{\mbox{1^*}})
Is there any way to do this?
Thank you,
