We derive explicit formulas for converting between rational interpolants in barycentric, rational Krylov (RKFUN), and Newton form. We show applications of these conversions when working with rational approximants produced by the AAA algorithm Y. Nakatsukasa et al. (2018) [6] within the Rational Krylov Toolbox and for the solution of nonlinear eigenvalue problems.
