In this second remark we present a revised correction to Algorithm 1010 [A. Orellana and C. De Michele 2020] with respect to the one already proposed in the remark on Algorithm 1010 [C. De Michele 2022]
Aiming to provide a very accurate, efficient, and robust quartic equation solver for physical applications, we have proposed an algorithm that builds on the previous works of P. Strobach and S. L. Shmakov. It is based on the decomposition of the …
