source: build-install/usr/lib/python3.14/site-packages/scipy/signal/_filter_design.py:5212

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.)
