| Abstract: | This paper gives inverse element estimate formula in strictly diagonally dominant tridiag-onal matrix. We get better consequence than that theorem in paper l]. That is, the restrictive condition of nonnegative in paper l] is excepted, and let theorem in paper l] becoming an especial example in our paper that. |
