Vector Fitting is an algorithm used to approximate frequency-domain responses with rational functions. It is based on pole relocation through a least-squares fitting process, ensuring stable and accurate approximations. This repo contains an implementation of the VF algorithm, inspired by the original vectfit3.m MATLAB script by Bjørn Gustavsen.
