[HTML][HTML] Swapping 2× 2 blocks in the Schur and generalized Schur form
Journal of Computational and Applied Mathematics, 2020•Elsevier
… In this paper we describe how to swap two 2 × 2 blocks in a real Schur form and a
generalized real Schur form. We pay special attention to the numerical stability of the

Abstract
In this paper we describe how to swap two 2 × 2 blocks in a real Schur form and a generalized real Schur form. We pay special attention to the numerical stability of the method. We also illustrate the stability of our approach by a series of numerical tests.
