You can mix ublas sparse matrices with Blitz's vectors,
using raw memory adaptors. Both Blitz and ublas support it:

ublas: via shallow_array_adaptor, undocumented, please examine the code,
ask in this list or see archives - there were huge amount of conversations
in depth on this subject.
As of Blitz - read it's docs, it is well covered there.
