[ODE] SuperLU big matrix solver...

[Adam D. Moss]

Hello.  Stumbled across this and wondered if it (and/or the
theory behind it) could be useful for ODE's solvers:

The latest version looks like it has a more optimal operating
mode for symmetric matrices (ODE's system of linear eqns is
essentially symmetric isn't it?).  My maths isn't up to evaluating
SuperLU very well, but taking it for a quick spin with the test
apps, it looks like it does what it says on the tin.
