r-循环矩阵特征值反问题
Inverse Eigenvalue Problems for r- Circular Matrices
【摘要】 本文介绍了r-循环矩阵的基本内容,提出了r-循环矩阵特征值反问题Ⅰ,Ⅱ,Ⅲ,利用r-循环矩阵的基本性质给出了它们有解的充分必要条件及求解算法。
【Abstract】 In this paper, the elementary knowledge of r- circular matrices is described briefly and three kinds of inverse eigenvalue problems denoted by Ⅰ,Ⅱ,Ⅲ on r- circular matrices are proposed. The solvability of the problems are dis- cussed and the necessary and sufficient conditions for solution of the three problems, solutions and corresponding calcu- lating methods are offered. Furthermore some related numerical examples are given.
