Synopsis
#include <flint/ca_mat.h>void ca_mat_solve_lu_precomp(ca_mat_t X, const slong * perm, const ca_mat_t A, const ca_mat_t B, ca_ctx_t ctx)sourcevoid ca_mat_solve_fflu_precomp(ca_mat_t X, const slong * perm, const ca_mat_t A, const ca_t den, const ca_mat_t B, ca_ctx_t ctx)sourceSolves AX = B given a nonsingular LU decomposition (permutation perm and the matrix A holding L and U), or a fraction-free one with denominator den, as computed by ca_mat_nonsingular_lu or ca_mat_nonsingular_fflu. The decomposition is not checked. X may be the same object as B but not as A.
