广义双对角占优矩阵的Schur余和对角Schur余

On the Schur Complements and the Diagonal-Schur Complements of Generalized Doubly Diagonally Dominant Matrices

对广义双对角占优矩阵的Schur余和对角Shuer余进行了分析;给出了广义双对角占优矩阵的对角Schur余的一个性质,及广义双对角占优矩阵Schur余的特征值分布情况.

In this paper,we obtain a theorem on the eigenvalues distribution of Schur complements of generalized doubly diagonally dominant matrices.Futher,we give a property of diagonal-Schur complements on generalized doubly diagonally dominant matrices.
