#4742: Wrap Pari's generalised Smith form (when it is fixed)
---------------------------+------------------------------------------------
Reporter: davidloeffler | Owner: somebody
Type: enhancement | Status: new
Priority: minor | Milestone: sage-feature
Component: number theory | Keywords: elementary divisors
---------------------------+------------------------------------------------
Pari has a function ("nfsnf" in GP, "nfsmith" in the C library) that
calculates the generalised elementary divisors (a list of ideals rather
than elements) for a matrix over the ring of integers of a number field.
In the current pari stable (2.3.4) and testing (2.4.2) this is so broken
as to be useless, but Karim Belabas has fixed it in svn, so when we catch
up with Pari 2.4.3 it would be worth providing a Sage wrapper.
