ARPACK bindings are attached. Feel free to commit them to the bindings
CVS or send comments.
Cholesky, CG and BiCGSTAB are in the works, but I still have to clean
them up a little bit.

Nope, not yet. Dr. Tim Davis (UMFPACK's author) has apparently devised a
sparse Cholesky algorithm that can be implemented in ~80 lines of
code. Might be worth looking at, even reimplementing, to avoid another
kludgy binding.

How about a ublas-extras archive that contains the bindings and these
algorithms?
BTW, I believe that the patches in my original email fix important bugs
in UBlas. They fix a crash and a compiler error. I wonder why no-one has
at least said what they don't like about them.
Have a good weekend,
Andreas
