Yes, it does. I'm using ublas matrices and vectors and the bindings to atlas and
lapack. Most methods from atlas and lapack are available as bindings from the
boost sandbox repository (it's not part of the official releases); some less
frequently used ones are missing by now.

In terms of speed I don't see a difference w.r.t. C-like objects. And the use of
the optimized atlas library really boosts performance.

Just my two cents,

Peter Melchior
