Synopsis
#include <flint/arb_mat.h>void arb_mat_approx_solve_lu_precomp(arb_mat_t X, const slong * perm, const arb_mat_t A, const arb_mat_t B, slong prec)sourceCompute an approximate LU decomposition with partial pivoting, returning zero if an exactly zero pivot column is encountered, and solve with such a decomposition (assumed to come from arb_mat_approx_lu).
