---

function triouter(A:RealMatrixLike, L:RealMatrixLike) -> RealMatrixLike

Matrix-lower-triangular-matrix outer product.

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

Returns Result $C = AL^\top$.

function triouter(L:RealMatrixLike) -> RealMatrixLike

Lower-triangular-matrix outer product.

• L Lower-triangular matrix $L$.

Returns Result $S = LL^\top$.
