Updating the QR decomposition of block tridiagonal and block Hessenberg matrices
We present an efficient block-wise update scheme for the QR decomposition of block tridiagonal and block Hessenberg matrices. For example, such matrices come up in generalizations of the Krylov space solvers MinRes, SymmLQ, GMRes, and QMR to block ...
Inverse eigenvalue problems of tridiagonal symmetric matrices and tridiagonal bisymmetric matrices
The problem of generating a matrix A with specified eigenpairs, where A is a tridiagonal symmetric matrix, is presented. A general expression of such a matrix is provided, and the set of such matrices is denoted by S"E. Moreover, the corresponding least-...
Block ILU Preconditioners for a Nonsymmetric Block-Tridiagonal M-Matrix
AbstractWe propose block ILU (incomplete LU) factorization preconditioners for a nonsymmetric block-tridiagonal M-matrix whose computation can be done in parallel based on matrix blocks. Some theoretical properties for these block ILU factorization ...
