gr_poly_inv

Synopsis#include <flint/gr_poly.h>
int gr_poly_inv(gr_poly_t res, const gr_poly_t poly, gr_ctx_t ctx)source

Sets res to the inverse of poly in R[x]. This succeeds only for a constant polynomial with an invertible constant (and for the zero polynomial over the zero ring); any polynomial of length at least 2 gives GR_DOMAIN.
