The mathematical basis and a prototype implementation of a new polynomial rootfinder with quadratic convergence.
Formulas developed originally by Weierstrass have been used since the 1960s by many others for the simultaneous determination of all the roots of a polynomial. Convergence to simple roots is quadratic, but individual approximations to a multiple root converge only linearly. However, it is shown here...
