ON THE REDUCTION OF A HAMILTONIAN MATRIX TO HAMILTONIAN SCHUR FORM
David S. Watkins · 2006
Abstract. Recently Chu, Liu, and Mehrmann developed an O(n 3) structure preserving method for computing the Hamiltonian real Schur form of a Hamiltonian matrix. This paper outlines an alternate derivation of the method and alternate explanation of why the method works. Our approach places emphasis eigenvalue swapping and relies less on matrix manipulations.
