int lapack_solve_triangular
(
	const Matrix *A_mp,
	const Matrix *B_mp,
	Matrix **X_mpp
);

DESCRIPTION

    A * X = B
where A is lower-triangular. Avoids expensive inversion and/or factorization required in the general problem. If this routine was not compiled with lapack available, then it returns ERROR with an appropriate error being set.

RETURNS

NO_ERROR on success, and ERROR on failure, with an appropriate error message being set.

DISCLAIMER

This software is not adequatedly tested. It is recomended that results are checked independantly where appropriate.
