Ah,
Ondrej,
Yes, the relativity.py example works. However, I want to do indicial
tensor algebra and was hoping tensor.py is a start in that direction.
The tensor.py included with the dist sympy-0.6.3 in examples is what I
hacked. I don't see a way to attach a file in posting. I would have
attached t

Ondrej,
I have taken the tensor.py script and have stripped out most of it,
wanting to see just how far it gets before crashing. Here is what I
have:
from sympy import exp, Symbol, sin, Rational, Derivative, dsolve
from sympy.core import Basic, Function
from sympy.matrices import Matrix

That's a good question.
Thank you all.
Ondrej,
I tried again and I think the structure can be kept as is,
only that I the mutable default set([]) should be avoided since
it is assigned one per class.
So in the definition of an instance I needed to replace
V=Vertex('V')
with
V=Vertex('V',set([]))

What is the best way to replace tan(x) with sin(x)/cos(x)?
*.match() does not seem to be suited, because I don't care where tan
(x) occurs, I just want to replace it.
WildFunction() seems to be broken.

There is also igraph with a python interface.

We don't, as far as I know and it would be cool to have it. Thanks for doing it.

Very cool! Thanks a lot for sharing it. Let's implement it in sympy.
