Synopsis
#include <flint/fq_zech_poly.h>slong _fq_zech_poly_gcd_euclidean_f(fq_zech_t f, fq_zech_struct * G, const fq_zech_struct * A, slong lenA, const fq_zech_struct * B, slong lenB, const fq_zech_ctx_t ctx)void fq_zech_poly_gcd_euclidean_f(fq_zech_t f, fq_zech_poly_t G, const fq_zech_poly_t A, const fq_zech_poly_t B, const fq_zech_ctx_t ctx)GCD by the Euclidean algorithm for a possibly reducible defining polynomial: either set f = 1 and G to the GCD (monic in the non-underscore version) and return its length, or set f to a nontrivial factor of the defining polynomial when a leading coefficient is not invertible, leaving G undefined. The underscore version requires lenA \ge lenB > 0 and space for lenB coefficients.
