Hi,

(I realize I reply to an older mail in this thread, but this context is 
more relevant)

The currently implemented matrix operations (transform strategies) are 
using ublas.

This is not (yet) a boost library, and already for long in the review 
queue, but it is worth to visit. I hope that it will become part of 
Boost and we could then use that library (instead of current Ublas usage).

The author (Emil Dotchevski) is already a Boost Author.
