Re: [eigen] projects using Eigen2 ?

OK thanks; we can already mention that; do keep us informed if your
company releases (even partial) source code.

Thanks; the reason why it's not well-known yet is that it's too new;
the whole Eigen project is 2 years old, and Eigen 1 wasn't really
newsworthy, it was just 2000 LOC and had a very limited feature set
and no expression templates. Eigen 2 only started to be ready for
real-world usage a few monthes ago, around August.

In our experience, the serious "competitors" to Eigen2 are neither
tvmet (eigen 2 is better in about every respect) nor ublas (it's one
of the slowest BLAS) not Blitz (not a linear algebra library, using it
as such gives bad performance).

We've found that the more serious free alternatives to Eigen2 were
rather ATLAS (probably the fastest free BLAS, but we're faster than it
in every benchmark), perhaps FLENS (don't know much about it, at least
Keir was happy to switch from it to Eigen2). Non-free alternatives
incluse Intel MKL and GOTO, and they are faster than Eigen2 for
certain operations while Eigen2 is faster for others.
