BLU Factorization for Block Tridiagonal Matrices and Its Error Analysis ()
ABSTRACT
A block representation of the BLU factorization for block tridiagonal matrices is presented. Some properties on the factors obtained in the course of the factorization are studied. Simpler expressions for errors incurred at the process of the factorization for block tridiagonal matrices are considered.
