Frenzel, "Polynomial Root Finding," <i>IEEE Signal Processing Letters,</i> 1994.https://hdl.handle.net/1911/20045Journal PaperFinding 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.engDSPGeneral DSPJournal articleDSPhttp://dx.doi.org/10.1109/97.329845
