Hi Per,
You can indeed use the boost-sandbox bindings for LAPACK (dense
matrices) or UMFPACK or MUMPS for sparse matrices. All are available in
the boost-sandbox module boost/numeric/bindings.
Examples are available from the libs directory in boost-sandbox.
Some examples can also be found on http://tinyurl.com/2h4j5f
or http://www.cs.kuleuven.be/publicaties/rapporten/tw/TW506.abs.html
It is some work to get everything working. Hope it is fine.
