Has anyone ever imported the LAPACK routines to IDL?
Does anyone know a good way to import/compile them in IDL?
Because I need these routines:
DGEES DGGES ZGEES ZGGES DGEBAL ZGEBAL DGEBAK ZGEBAK
And the LAPACK routines of IDL can not do what I have to do (Schur
decomposition of matrix and pencils, matrix and pencil balancing).

Thanks

Guido

Yes, I do and so would you if you would RTM (I avoid the F because that
would be rude). Seriously, this is all described in the IDL documentation
and usable demo code is included in the IDL distro (check <IDL_DIR>/external
and subdirectories). So all you have to do is take that code (I recommend
the call_external method for beginners) and swap the demo routine for any of
those mentioned by you. This will take some time but I doubt that you find
anyone writing this for you for free.

Good luck,
Haje
