Comments on "A Simple and Accurate Algorithm for Barycentric Rational Interpolation"

For original paper see L. Knockaert , ibid., vol.15, p.154-7, (2008). It is pointed out that the null space of Lowner matrices for the Barycentric rational interpolation can also be solved by an algebraic algorithm based on the Grobner basis theory. This algorithm is known for solving minimal rational interpolation problems in the context of system and coding theory.
