Synopsis
#include <flint/acb_mat.h>void _acb_mat_companion(acb_mat_t mat, acb_srcptr poly, slong prec)sourcevoid acb_mat_companion(acb_mat_t mat, const acb_poly_t poly, slong prec)sourceSet the matrix mat to the companion matrix of the polynomial of degree (the underscore version reads coefficients). If the leading coefficient cannot be inverted, the result is indeterminate. Wrappers of _gr_mat_companion and gr_mat_companion.
