Synopsis
#include <flint/fmpz_poly_mat.h>int fmpz_poly_mat_inv(fmpz_poly_mat_t Ainv, fmpz_poly_t den, const fmpz_poly_mat_t A)sourceSets (Ainv, den) to the inverse of the square matrix A, so that A \cdot \mathit{Ainv} = \mathit{den} \cdot I with \mathit{den} = \det A, and returns 1 if A is nonsingular; returns 0 if it is singular. Ainv may be A.
