minimaxApprox: Minimax Approximation of Functions by Polynomials and Rational Functions
Implements minimax approximation of functions via the Remez (1962) algorithm for polynomials and the Cody-Fraser-Hart (1968) <doi:10.1007/BF02162506> algorithm for rational functions, as well as their barycentric formulations: the Pachón-Trefethen (2009) <doi:10.1007/s10543-009-0240-1> algorithm for polynomials and the Filip-Nakatsukasa-Trefethen-Beckermann (2018) <doi:10.1137/17M1132409> algorithm for rational functions, which provide improved numerical stability at higher degrees and on wider intervals.
