Re: [eigen] FLENS C++ expression template Library has excellent documentation

[Andre Krause <post@xxxxxxxxxxxxxxxx>]

no, i just wanted to show you that lib, because it seems not to be known widely.
and the documentation is very nice. it describes in an easy to follow manner how
static polymorphism and expression templates and closures work - for people who
have no idea about these techniques (like me ;-).
and they describe very detailed their architecture - so it might be possible
that some new ideas might arise .

i know that the great thing about eigen2 is that you do NOT need to install blas
and lapack !!

so in summary, just adding another lib to the list of known , avtively developed
linear algebra c++ libs. might also be interesting when it comes to benchmarking.

kind regards, andre
