Abstract : The real Schur form of a real square matrix is block up per triangular. The authors study techniques for performing orthogonal similarity transformations that preserve block triangular form but alter the order of the eigenvalues along the (block) diagonal. Keywords: Software economizer, Implementation, Cholesky factor, Numerical tests. (kr)
