摘要 本文研究广义次对称矩阵的左右逆特征对问题及其最佳逼近问题.利用广义次对称矩阵的特殊性质得到问题有解的充要条件以及通解表达式.同时给出其唯一的最佳逼近解以及求最佳逼近解的算法与实例. In this paper, left and right inverse eigenpairs problem for κ-persymmetric matrices and its optimal approximate problem are considered. By using the special properties of κ-persymmetric matrices, the necessary and sufficient conditions for the solvability of the problem are derived, and its general solution's expression is given. Furthermore, the optimal approximate solution and the algorithm to obtain the optimal approximate solution are provided.
