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

Lower-triangular-matrix-scalar solve.

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

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

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

Lower-triangular-matrix-vector solve.

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

Returns Solution of $x$ in $Lx = y$.

function trisolve(L:RealMatrixLike, y:RealMatrixLike) -> RealMatrixLike

Lower-triangular-matrix-matrix solve.

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

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