LAPACK also has tridiagonal functions. In the spline code we are
doing a couple of rotations outside the solver so that the cyclic
case doesn't need a full matrix solve. I doubt you want to support
a mostly banded matrix class though.
Another matrix attribute to consider is a transpose marker, but like
triangular matrices, this only gives a small speedup compared to the
cost of the op.
