Abstract For a nonnegative square matrix, a method of constructing a stability indicator in the form of a polynomial in matrix coefficients is presented. Additionally, an algorithm for indicator calculation is described and the relationship of the resulting indicator with determinants of some matrices built on the basis of the original one is demonstrated.

关于非负矩阵的稳定性指标

摘要 针对非负方阵，提出了一种以矩阵系数多项式形式构造稳定性指标的方法。此外，还描述了一种指标计算算法，并展示了所得指标与在原始指标基础上构建的某些矩阵的行列式之间的关系。
