- genbarywts.m for generating barycentric weights
- hermiteval.m for evaluating Lagrange and Hermite interpolants using the (numerically stable) second barycentric form
- gcmp.m for the generalized companion matrix pencil, allowing roots of polynomial expressed in Lagrange and Hermite interpolation basis.
- bhip.mpl for Barycentric Hermite Interpolating Polynomial in Maple. Also includes "distrib" to convert first barycentric form to Lagrange form, and CMP for the companion matrix pencil.
- Interpolating (z-1/4)^2(z-1/2)^2(z-3/4)^2 at four points with confluency 2 gives good accuracy
- Runge example with confluency 2
