trimul

function trimul(L:RealMatrixLike, x:RealVectorLike) -> RealVectorLike

Lower-triangular-matrix-vector product.

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

Returns Result $y = Lx$.

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

Lower-triangular-matrix-matrix product.

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

Returns Result $C = LB$.
