triinner

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

Lower-triangular-matrix-vector inner product.

  • L Lower-triangular matrix LL.
  • x Vector xx.

Returns Result y=Lxy = Lx.

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

Lower-triangular-matrix-matrix inner product.

  • L Lower-triangular matrix LL.
  • B Matrix BB.

Returns Result C=L⊤BC = L^\top B.

function triinner(L:RealMatrixLike) -> RealMatrixLike

Lower-triangular-matrix inner product.

  • L Lower-triangular matrix LL.

Returns Result S=L⊤LS = L^\top L.
