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 pq such that r(γi)=f(γi) at prescribed sample points {γi}Li=1 , and then find the roots of...
