Reordering diagonal blocks in real Schur form

Primary tabs

Bojanczyk, A. [Cornell Univ] Van Dooren, Paul [UCL]

We present a direct algorithm for computing an orthogonal similarity transformation which interchanges neighboring diagonal blocks in a matrix in real Schur form. The algorithm does not require the solution of the associated Sylvester equation. Numerical tests suggest the backward stability of the scheme.
