Synopsis
#include <flint/fmpz_mpoly.h>int fmpz_mpoly_discriminant(fmpz_mpoly_t R, const fmpz_mpoly_t A, slong var, const fmpz_mpoly_ctx_t ctx)sourceSets R to the discriminant of A with respect to the variable of index var, (-1)^{d(d-1)/2} \operatorname{res}(A, A')/\operatorname{lc}(A) up to the convention for low degrees used by mpoly_univar_discriminant, and returns 1, or returns 0 on failure.
