TY - GEN A1 - Mehrmann, Volker A1 - Schröder, Christian A1 - Watkins, David S. T1 - A new block method for computing the Hamiltonian Schur form N2 - A generalization of the method of Chu, Liu and Mehrmann for the computation of the Hamiltonian real Schur form is presented. The new method avoids some of the difficulties that may arise when a Hamiltonian matrix has tightly clustered groups of eigenvalues. A detailed analysis of the method is presented and several numerical examples demonstrate the superior behavior of the method.
