triinnersolve

---

function triinnersolve(L:RealMatrixLike, y:RealScalarLike) -> RealMatrixLike

Lower-triangular-matrix-scalar inner solve.

• L Lower-triangular matrix $L$.
• y Scalar $y$.

Returns Solution of $B$ in $LB = Iy$.

function triinnersolve(L:RealMatrixLike, y:RealVectorLike) -> RealVectorLike

Lower-triangular-matrix-vector inner solve.

• L Lower-triangular matrix $L$.
• y Vector $y$.

Returns Solution of $x$ in $y = L^\top x$.

function triinnersolve(L:RealMatrixLike, C:RealMatrixLike) -> RealMatrixLike

Lower-triangular-matrix-matrix inner solve.

• L Lower-triangular matrix $L$.
• C Matrix $C$.

Returns Solution of $B$ in $C = L^\top B$.
