Synopsis
#include <flint/fq_mat.h>void fq_mat_solve_tril(fq_mat_t X, const fq_mat_t L, const fq_mat_t B, int unit, const fq_ctx_t ctx)void fq_mat_solve_triu(fq_mat_t X, const fq_mat_t U, const fq_mat_t B, int unit, const fq_ctx_t ctx)Set X = L^{-1} B, respectively X = U^{-1} B, for a square lower, respectively upper, triangular matrix with nonzero diagonal entries. If unit is nonzero, the diagonal is assumed to consist of ones and is not read. Only the triangular part of the matrix is read. Aliasing of X and B is allowed. Classical substitution is used if B has fewer than 64 rows or columns, and block recursion otherwise.
