Evaluation schemes in the ring of quaternionic polynomials
In this paper we focus on computational aspects associated with polynomial problems in the ring of one-sided quaternionic polynomials. The complexity and error bounds of quaternion arithmetic are considered and several evaluation schemes are analyzed from their complexity point of view. The numerical stability of generalized Hornerâs and Goertzelâs algorithms to evaluate polynomials with quaternion floating-point coefficients is addressed. Numerical tests illustrate the behavior of the algorithms from the point of view of performance and accuracy.Research at CMAT was ïŹnanced by Portuguese Funds through FCT - Fundação para a CiĂȘncia e a Tecnologia, within the Project UID/MAT/00013/2013.
