size :: Hermitian sh a -> sh

fromList :: (C sh, Storable a) => Order -> sh -> [a] -> Hermitian sh a

toSquare (stack a b c)

=

toSquare a ||| b
===
adjoint b ||| toSquare c

It holds order (stack a b c) = order b. The function is most efficient when the order of all blocks match.

anticommutator :: (C vert, C horiz, C height, Eq height, C width, Eq width, Floating a) => Full vert horiz height width a -> Full vert horiz height width a -> Hermitian width a

anticommutator A B = A^H * B + B^H * A

Not exactly a matrix anticommutator, thus I like to call it Hermitian anticommutator.

For symmetric eigenvalue problems, eigensystem and schur coincide.
