Title: Polynomial Root Finding
Author: Lang, Markus; Frenzel, Bernhard-Christian
Type: Journal Paper
Keywords: DSP
Citation: M. Lang and B. Frenzel, "Polynomial Root Finding," IEEE Signal Processing Letters, 1994.
Abstract: Finding polynomial roots rapidly and accurately is an important problem in many areas of signal processing. We present a program which is superior in speed and accuracy to the best methods to our knowledge, i.e., Jenkins/Traub program and the eigenvalue method. Based on this we give a simple approach to improve the accuracy for spectral factorization in the case there are double roots on the unit circle.
