It sounds like you're describing ATLAS (
That's the option I'm leaning towards right now.

I presently only need SVD (singular value decomposition) functionality,
but my requirements are fairly open-ended beyond that (well... what can
make the system do ???).

Others have suggested Boost libs (thanks, BTW), but I'm afraid that c++
doesn't figure into my current design. However, the idea is still nice
to chew on, and I'm not adamantly opposed to an OO redesign. I just
haven't had time to adequately "play around" with the rtems/c++

ummm... I mean: "experiment with"... ;)

I'll post my findings if/when I know more...
