Rational Minimax Approximation via Adaptive Barycentric Representations
Computing rational minimax approximations can be very challenging when there are singularities on or near the interval of approximation — precisely the case where rational functions outperform polynomials by a landslide. We show that far more robust algorithms than previously available can be developed by making use of rational barycentric representations whose support points are chosen in an a...
متن کاملMinimax principle and lower bounds in H2-rational approximation
We derive lower bounds in rational approximation of given degree to functions in the Hardy space H2 of the unit disk. We apply these to asymptotic error rates in rational approximation to Blaschke products and to Cauchy integrals on geodesic arcs. We also explain how to compute such bounds, either using Adamjan–Arov–Krein theory or linearized errors, and we present a couple of numerical experim...
متن کاملLebesgue Constant Minimizing Bivariate Barycentric Rational Interpolation
The barycentric form is the most stable formula for a rational interpolant on a finite interval. The choice of the barycentric weights can ensure the absence of poles on the real line, so how to choose the optimal weights becomes a key question for bivariate barycentric rational interpolation. A new optimization algorithm is proposed for the best interpolation weights based on the Lebesgue cons...
متن کاملRecent advances in linear barycentric rational interpolation
Well-conditioned, stable and infinitely smooth interpolation in arbitrary nodes is by no means a trivial task, even in the univariate setting considered here; already the most important case, equispaced points, is not obvious. Certain approaches have nevertheless experienced significant developments in the last decades. In this paper we review one of them, linear barycentric rational interpolat...
متن کاملRational Transform Approximation via the Laguerre Spectrum
In t roduc t ion An important class of functions from the point of view of signal representation and approximation is the class with n th order rational Laplace transforms. These functions arise naturally in such fields as model identification and timedomain synthesis. The problem of finding the best n th order rational function to represent a given time function is, therefore, important; unfor...
