Abstract: We will discuss the following topics: attractions of the real tridiagonal case, relative eigenvalue condition number for matrices in factored form, dqds, triple dqds, error analysis, eigenvectors of the balanced form, twisted factorizations and generalized Rayleigh quotient iteration. Some numerical results will be shown.
