A subspace iteration for symplectic matrices
Electronic transactions on numerical analysis, Tome 43 (2015)
We study the convergence behavior of an orthogonal subspace iteration for matrices whose spectrum is partitioned into three groups: the eigenvalues inside, outside, and on the unit circle. The main focus is on symplectic matrices. Numerical experiments are provided to illustrate the theory.
