Synopsis
#include <flint/acb_poly.h>void _acb_poly_product_roots(acb_ptr poly, acb_srcptr xs, slong n, slong prec)sourcevoid acb_poly_product_roots(acb_poly_t poly, acb_srcptr xs, slong n, slong prec)sourceSet poly to (x - x_0)(x - x_1) \cdots (x - x_{n-1}). The underscore version writes n + 1 coefficients. Wrappers of _gr_poly_product_roots, which multiplies the factors in a balanced tree. For a real polynomial with roots in conjugate pairs, arb_poly_product_roots_complex avoids the spurious imaginary parts.
