- What would need to be done:
-
- - pick the right functionality from LAPACK etc, the minimum imho
- would be general qr and qz
- - use f2c to translate the routines, probably ignoring possible
- inefficiencies (?) from column/row orientation reversal to start with
- - link them into J
-
- I'm familiar with the first 2, having done the same sort of thing to
- get domino working in the compiler I'm hacking. But I haven't used
- linkJ yet... I do intend to do this someday, but seeing as I have lots
- of other things to due these days can't say when.
