# EPS_HAMILT

A structured Hamiltonian eigenvalue problem.

## Note

The problem is formulated as \(Hx=\lambda x\), where \(H\) has a Hamiltonian structure,

\[\begin{split}H = \begin{bmatrix} A & B \\ C & -A^* \end{bmatrix},\end{split}\]
where \(A\), \(B\) and \(C\) are either real with \(B=B^T\), \(C=C^T\), or complex with \(B=B^*\), \(C=C^*\).
