QPmR - Quasi-Polynomial Mapping Based Rootfinder
Original language description
QPmR is a Matlab function for computation and analysis of spectrum of characteristic quasi-polynomials of both retarded and neutral time delay systems. Utilizing the distribution diagram, the spectral features are analysed first. Next, all the quasi-polynomial zeros located in a defined region of the complex plane are computed using mapping based approach. In order to optimize the performance, the recursive computational scheme is involved. The algorithm can compute up to hundreds of roots located in the given region.
