The goal of this paper is to compute the eigenvector of symmetrictridiagonal matrix T corresponding to the given approximate eigenvalue λ, by us-ing one step of inverse iteration for certain chosen right vector ek. C...
Let Tn be an n×n unreduced symmetric tridiagonal matrix with eigenval- ues λ1<λ2<…<λn.Wk is an (n-1)×(n-1) submatrix by deleting the kth row and kth column from Tn,k=1,2,…,n.Letμ1≤μ2≤…≤μn-1, be the eigen...
