- %HESS Hessenberg form.
- % The Hessenberg form of a matrix is zero below the first
- % subdiagonal. If the matrix is symmetric or Hermitian,
- % the form is tridiagonal. [P,H] = HESS(A) produces a unitary
- % matrix P and a Hessenberg matrix H so that A = P*H*P' and
- % P'*P = EYE(P). By itself, HESS(A) returns H.
