Don't know if this is any use, but to me (not knowing Fortran nearly
so well as C++) this looks pretty useful:
http://www.caam.rice.edu/software/ARPACK/arpack++.html
http://www.ime.unicamp.br/~chico/arpack++/
It provides a nice high-level interface on top of ARPACK. I could see
it being useful on

I made a start at an ARPACK wrapper, see

and the short thread at scipy-dev

Here's something I've been wondering: is it ok to port Matlab
functions over to python? If so, then it's maybe an afternoon's work
to get eigs working, given eigs.m and python Arpack wrappers.
I'm 99% sure it would *not* be kosher to copy-paste their code
directly, but it's not a copy paste job b

Make that AA'.
