Mo,
in your compile options use BOOST_UBLAS_MOVE_SEMANTICS.

(i.e. in gcc that would be -DBOOST_UBLAS_MOVE_SEMANTICS)

I would like to make a couple of changes in the bounded types and push the idea to make the move_semantics default, as it seems all compilers support copy elision and even if they don't there is no penalty.

see also:
http://www.boost.org/doc/libs/1_43_0/libs/numeric/ublas/doc/options.htm

There had been some discussion in the past and I see that with the new standard we will be able to go even further in totally eliminating temporaries.
Take a look at this also:

Best
Nasos
