Approximation of functions is an enabling technology for scientific computing. The Julia ecosystem has excellent options for polynomial-based approximation methods. New algorithms for approximation by ratios of polynomials have sparked increasing interest in computational rational approximation. The RationalFunctionApproximation.jl package supplies the fastest known versions of these methods for approximation of functions over an interval or any connected domain in the complex plane.
