The solution of the equation AX + X⋆B = 0
... and JB , then the equation JA X − XJB = 0 is decoupled into smaller independent equations JiA Xij −Xij JjB = 0 for each block Xij , 1 ≤ i ≤ p and 1 ≤ j ≤ q. Thus, the problem of solving (2) reduces to solving it when the coefficients are single Jordan blocks. The key advantage of this approach is that ...

... and we assume ri 6= 0. Then, Hn is upper triangular and A = (G1 G2 · · · Gm−1 )Hn = QR is a QR-factorization of A. Proof idea: Only one rotator required to bring one column of a Hessenberg matrix to a triangular. * Matlab: Explicit QR-factorization of Hessenberg qrg ivens.m ∗ QR-method lecture 2 ...
