C++ libraries for scientific computing anyone?

[José Luis Gómez Dans <nospam [at] sheffield.ac.uk>]

Hi!
	I am using fortran 77 at the moment for most of my work. I know
people will rant about it to their heart's content, but it is extremely
useful for some things (complex numbers). While the same can be done in
C, the amount of code to do something simple is doubled. It turns out
that by doing it in fortran 90, you half most of the work w.r.t. ftn77,
as it has all sorts of nice types: matrices, arrays,  and you can
operate on them as a whole.

	However, rather than go through all that, I was wondering
whether someone uses a C++ library for numerical work. I know of the
existance of a number of them (see http://www.oonumerics.com, I think),
but that's the problem: I do not want my code to go down the drain when
the maintainer of a very alpha library decides to dedicate his time to
something else. From what I see, the development of these libraries is
very slow, and I was wondering whether someone uses one of these so
he/she can recommend it (or not!).

	It's getting late, can't write properly me...
	Cheers,
	José
