Is there any interest in improving SymPy's handling of sequences as a GSoC
project? As a mathematics student, I often find myself checking identities
involving well-known, recursive sequences and their generating functions.
When
I use SymPy to do this I always end up cobbling together something that
works,
but is never quite satisfying.
I think that a rough set of goals would be this:
- Improve recursive sequence handling.
I took a stab at implementing a recursive sequence class earlier this
year,
but after using it for a while I think it could be better.
- Improve sequence usage throughout SymPy.
For instance, `rsolve` returns an expression, not a sequence.
- Implement well-known classes of sequences (C-finite, etc.).
Some of this exists scattered throughout SymPy. It should be organized
into
a cohesive module.
- Improve sequence documentation.
This isn't quite in line with the listed mathematics projects from last
year,
but I think it could be useful.
