triinner

---

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

Lower-triangular-matrix-vector inner product.

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

Returns Result $y = Lx$.

function triinner(L:RealMatrixLike, B:RealMatrixLike) -> RealMatrixLike

Lower-triangular-matrix-matrix inner product.

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

Returns Result $C = L^\top B$.

function triinner(L:RealMatrixLike) -> RealMatrixLike

Lower-triangular-matrix inner product.

• L Lower-triangular matrix $L$.

Returns Result $S = L^\top L$.
