In this note, we generalize an interesting recent characterization of tridiagonal M-matrices whose inverse is still tridiagonal to any acyclic matrix. We discuss a possible extension. Several illustrative examples are provided.

在其逆也是非循环的非奇异非循环 M 矩阵上

在本笔记中,我们概括了三对角 M 矩阵的一个有趣的近期特征,其逆仍然是任何无环矩阵的三对角矩阵。我们讨论了一个可能的扩展。提供了几个说明性示例。
