An Implementation of the Iterative Rational Krylov Method for Optimal H2 Model Reduction

The IRK method has recently attracted attention because of its effectiveness in real world applications, as well as because of its mathematical elegance. We analyze the convergence of fixed point iterations behind the IRK idea, and show how proper stopping criterion translates into a backward stability relation. Both issues (convergence, stopping criterion) have impact on the floating point implementation. We present a new mathematical software, based on the new theoretical development.
