P-矩阵子类的一些推广及应用

Generalizing Some Subclasses of P-matrices

给出M B+-矩阵的概念,讨论其简单性质,应用这些性质来定位矩阵的特征值包含区域,并举例来验证定位方法的有效性.该定位方法优于一些已知结果.

The defination of MB＋ - matrix is given and its properties that are used to localize the real eigenvalues of a real matrix, and an example is given to verify the effectiveness of this method. The method is better than some other known results.
