The Real Two-Zero Algorithm: A Parallel Algorithm to Reduce a Real Matrix to a Real Schur Form

Abstract

In this paper, we introduce a new method to reduce a real matrix to a real Schur form by a sequence of similarity transformations that are 3-D orthogonal transformations. Two significant features of this method are that (1) all the transformed matrices and all the computations are done in the real field, and (2) it can be easily parallelied. We call the… (More)
