摘要
本文研究了矩阵的复合型谱包含域,给出了边界定理,得到了改进的复合型谱包含域,作为应用得到了非奇异H-矩阵的更精确的判别条件．
In this paper, we maked a thorough study the compound-type spectral inclusion region of a matrix, given a bouns theorem, and obtained a modified compund-type spectral inclusion. As applications, a new criterion for nonsinguly H-matrices is obtained.
