| Abstract: | In this paper, a large system with a symmetric and essentially (2,2)-band matrix is reformulated as the product of two banded matrices for the purpose of obtaining a solution of a linear system more efficiently. An error term for the approximate solution is justified in the spirit of the work by Yan and Chung [1]. |
