摘要
本文证明了一类非对角占优矩阵是可逆的,并给出了其逆阵的上界,以及解相应扰动方程组的误差估计.从而使严格对角占优这一类矩阵的有关结论得到扩充,并成为本文定理的特例.
A class of nondiagonally dominant matrices are peoved to be invirtible; the upper bound of their inverse matrices and the error estimate for solving their perturbation equations are given. Thus the conclusion in relation to strictly diagonally dominant matrices can be extended and become a special case in the theorems posed by this paper.
