Stable polefinding and rational least-squares fitting via eigenvalues
A common way of finding the poles of a meromorphic function f in a domain, where an explicit expression of f is unknown but f can be evaluated at any given z, is to interpolate f by a rational function [Formula: see text] such that [Formula: see text] at prescribed sample points [Formula: see text]...
