Synopsis
#include <flint/acb_poly.h>void cd_poly_roots_initial_values(double * z_r, double * z_i, const double * p_r, const double * p_i, slong n, const double * z0, slong d)sourceSets z_r, z_i to n - 1 initial values for the roots of the polynomial with coefficients p_r, p_i of length n: the nonzero entries of z0 (of length d, or NULL), completed by points on circles given by the Newton polygon of (k, -\log|p_k|) [Bin1996].
