I was under the impression that most of the newer libraries took advantage
of vectorization for small, fixed size matrices through some mechanism, but
I usually don't know what I am talking about. ublas is a great, stable,library
and deserves a defense, even if its eventual deprecation is considered.

When will you have magma bindings for us :-)

I share the bias for linear algebra, but you still need to have a good matrix
library for basic operations (multiplication, slices, etc.) that is highly
expressive... so the container does matter a lot.
