[SciPy-dev] Tri-diagonal LAPACK Routines - Shall I interface them?

[Simon Clift]

Hi folks,

The tri-diagonal linear system routines (sdcz/gt*) in LAPACK don't seem to be 
interfaced to the scipy.linalg.flapack module.  These are (relatively) 
straightforward algorithms but it's always annoying when you need them and 
have to create your own implementation.

Is there a broader reason for not completing the interface?  Would anyone 
object if I went ahead and patched scipy/linalg/generic_flapack.pyf to allow 
the call?

Thanks
