dx.doi.org/doi:10.3888/tmj.20-4 This article discusses a recently developed Mathematica tool––a collection of functions for manipulating, evaluating and factoring quaternionic polynomials. relies on the package , which is available for download at w3.math.uminho.pt/QuaternionAnalysis. Introduction Some years ago, the first two authors of this article extended the standard Mathematica package implementing Hamilton’s quaternion algebra—the package —endowing it with … Continue reading Computational Aspects of Quaternionic Polynomials
