_ca_poly_inv_series, ca_poly_inv_series
Synopsis
#include <flint/ca_poly.h>Sets res to the power series inverse 1/f \bmod x^{\mathit{len}}. The constant term must be invertible: if it is zero the result consists of special values (unsigned infinity or Undefined), and Unknown values if it cannot be decided whether it is zero. Rational series are inverted over \mathbb{Q}; otherwise the classical recurrence or, for long series with fast multiplication, Newton iteration is used.
