scipy.signal._filter_design:_aberth
Signature
def _aberth(f, fp, x0, tol = 1e-15, maxiter = 50)Summary
Given a function f, its first derivative fp, and a set of initial guesses x0, simultaneously find the roots of the polynomial using the Aberth-Ehrlich method.
Extended Summary
len(x0) should equal the number of roots of f.
(This is not a complete implementation of Bini's algorithm.)
