groups and matrix groups

[kev devnull]

Hi all,

Are there any group/matrix group additions that the Sympy community would like someone with a background in math and cs to hack? I'm looking for a project. I'd be happy to do anything from helping to document new algebraic-related implementations to coding up new classes/modules. Please let me know.

Thanks!
Kevin

Hi Kevin

You should take a look at open issues related to matrices. You might get some clue about it.

I hope this helps!

Well, there's a high level thing, which is to refactor the matrices to
use a ground domain, so that every element must belong to that domain.

A simpler one would be to make matrices work with finite fields (like
FF(3)). I can't find the issue for it, but I think there are just some
simple changes that need to be made to prevent Matrix from converting
FF(3)(0) into just 0.

Is this still open... sorry. I got preoccupied with some other software and this got lost in the shuffle. Apologies! I'd like to help with the below. I'll check if it's still an open issue (assuming its in the issue tracker?)

Best,
Kevin

Aaron, Sudhanshu:

Sorry for the delay, I've been working on a few other projects and this got away from me. Apologies.

I would be interested in taking a look at:

1) Well, there's a high level thing, which is to refactor the matrices to

use a ground domain, so that every element must belong to that domain.

or

2) A simpler one would be to make matrices work with finite fields (like

FF(3)). I can't find the issue for it, but I think there are just some
simple changes that need to be made to prevent Matrix from converting
FF(3)(0) into just 0.

Assuming that they are still in the tracker. I'll go poke around. Will you let me know if they were never issued in the bug tracking system? Thanks. Looking forward to helping out.

They are still open issues, as far as I know. I thought there was an
open issue for the FF(3) thing, but I can't find it, so if you also
can't find it feel free to open a new one.
