numerics and scientific calculation

[Micah]

Hi,

I'm looking for a C++ package to use for scientific computing. Things that
would be nice:
* Fast matrix multiplication
* Arbitrary precision
* Equation solvers
* Easy to use!!

If you have any favorites (or horror stories) please share them.

Thanks,
Micah

For all the matrix + linear equation systems stuff you might
want to try LAPACK. It's in FORTRAN in actuality, but interfaces
OK with C++. You can also get it for free and it is very fast.

Apart from that, try a better group -- this one deals with
Standard C++ and no packages whatsoever.
