Error bounds for computed eigenvalues and eigenvectors. II
- 92 Downloads
In this paper, motivated by Symm-Wilkinson's paper , we describe a method which finds the rigorous error bounds for a computed eigenvalue λ(0) and a computed eigenvectorx(0) of any matrix A. The assumption in a previous paper  that λ(0),x(0) andA are real is not necessary in this paper. In connection with this method, Symm-Wilkinson's procedure is discussed, too.
