I found that cos(x).series() calling unbound methon series() from
sympy.core.expr but seems like that method doesn't provide printing values
to stdin. I'd like

Aaron suggested that Mod should inherit from Function. Renato didn't
have time to finish that PR, so I did it in PR 834 [2]. Maybe Aaron
can tell you more.

Yes. But feel free to discuss your ideas here on the mailing list
first, so we can guide you in the right direction before you spend a
bunch of time writing a proposal.

Well it doesn't matter to me if it does or not.
What should be the distinction for objects that do or do not derive
from Function? The fact that they represent an arithmetical
operation? If so, maybe we should have a logical base class for Pow,
Mul, Add, Mod, ...
Looking at the code, deriving
Hello all,
I'd like to announce my intent to apply for GSoC 2012. Last year, I
was accepted with Porting to Python 3, which I have completed
sucessfully (though no SymPy version with Python 3 support has been
released). I've since continued contributing to SymPy, mostly with
infrastructure work
Matt,
Thanks for the suggestions. Way 2 is more what I want to do(but not
quite) right now, but having the capability to do it via way 1 will be
welcomed!

Miham,
Thanks for the suggestion. It is rather elegant. However, I really
want to be able to assign a more convenient label to the created
symbols. That is, I want to assign
a11 - a_11, a12 - a_12, etc as the new symbols are defined. In a
loop would be nice, but I can not seem to get the
Hi Ondrej,
Your suggestion is very useful. I am now defining a matrix array with
element notation a_ij and label aij whereas your suggestion seems to
result in a_i_j and no more convenient to type label such as my
desired aij. How to do this?

Ondřej, I was thinking about studying those packages for Mathematica:
Ricci,
MathTensor,
FeynCalc
Were your referring to some other packages that I can look into? I
would like to check the established solution before I start designing
an API and so on.

Maybe you want also to look at xAct and related packages?

The code is GPL, maybe this can be a benefit
even given that sympy uses a BSD license.
