考虑具有部分特征值的非负特征值反问题,其目的是寻找一个非负矩阵,使得它最接近一个预先估计的非负矩阵,并且满足给定的特征值.本文提出了几种基于乘子交替方向法的求解非负反问题的迭代格式。我们还将我们的计划的对称情况下,规定的下限和规定的条目的情况下。数值试验(包括振动中的实际工程应用)表明所提出的迭代格式的效率。
We consider the nonnegative inverse eigenvalue problem with partial eigendata, which aims to find a nonnegative matrix such that it is nearest to a pre-estimated nonnegative matrix and satisfies the prescribed eigendata. In this paper, we propose several iterative schemes based on the alternating direction method of multipliers for solving the nonnegative inverse problem. We also extend our schemes to the symmetric case and the cases of prescribed lower bounds and of prescribed entries. Numerical tests (including a practical engineering application in vibrations) show the efficiency of the proposed iterative schemes.
