[Numpy-discussion] Some missing linalg things (wanted: LU decomposition)

[Bill B. <wb...@gm...>]

This url http://www.rexx.com/~dkuhlman/scipy_course_01.html seems to keep
turning up in my searches for numpy and scipy things,
but many of the linalg operations it lists don't seem to exist in recent
versions of numpy (or scipy).

Some of them are:

* norm
* factorizations: lu, lu_factor, lu_solve, qr
* iterative solvers: cg, cgs, gmres etc.

Did these things used to exist in Numeric but they haven't been ported
over?  Will they be re-introduced sometime?

In the short term, the one I'm after right now is LU decompose and solve
functionality.  Anyone have a numpy implementation?
