Okay, I imported the code base from
https://github.com/poeschko/sage
here:
http://trac.sagemath.org/ticket/15955
I really couldn't be bothered to import patch by patch as the original author
made an interesting - let's ignore Sage's version control - choice. So all his
commits are in one big commit.
Well, almost all:
- I fixed some things to adapt the patches to the current version of Sage and
- I didn't import the hack (I think it is) which allows to deal with this
situation:
sage: A = Matrix(ZZ, [[4,2,0],[2,1,0],[0,0,1]])
sage: A.LLL_gram()
...
ValueError: a matrix from Full MatrixSpace of 3 by 2 dense matrices over
Integer Ring cannot be converted to a matrix in Full MatrixSpace of 3 by 3
dense matrices over Integer Ring!
I'm not sure what should be done about this. In any case, I'd appreciate a
second set of eyes on this. Clearly, there's work to be done.
Cheers,
Martin
