Well, it seems we're in the homestretch of the SoC. I've been working on the FFLU decomp. Strangely I ran into some problems with modules not being installed properly but that finally regulated itself. Now I'm in the debugging phase and hopefully we're have a nice new fraction-free LU function.

I'm thinking that maybe I can squeeze in another Fraction-free inversion algorithm before next week...

*edit* Did I say inversion? I meant QR. So LU seems to be working but my QR one is still buggy. Oh well.

So for whatever reason I kept saying block LU, when I really meant fraction-free LU. Those are, of course, significantly different. I've been looking at this paper suggested by someone on the mailing list. It seems reasonably straight-forward (even the proof, which is surprising). I hope to finish the LU one soon and hopefully the QR one before the project finishes up.
