Ah!  I should have read closer.  BTW, since, based on our past emails,
you're interested in linear equation solvers for tridiagonal systems,
maybe you could let me know how you're solving tridiagonal systems with
ublas or lapack.  I'd appreciate it.

OK, I guess if I want to use  the ublas banded matrix I'll have to set
the values manually instead of using a subclass' CTOR and 3 std::vectors
as the CTOR args to do it :(

Thanks for the help, Petros.
