相似变换下对角优势矩阵研究

STUDY ON DIAGONAL DOMINANCE MATRIX UNDER SIMILARITY TRANSFORMATION

讨论了相似变换下矩阵对角占优的条件，并给出了一个应用实例．其中，定理１ 为一般相似变换下对角占优的充要条件，定理２ 与定理３ 为对角相似变换下的情况．

The conditions of diagonal dominance matrix under similarity transformation are studied in this paper,and an example of application is given A necessary and sufficent condition under general similarity transformation is given in theorem 1 ,Theorem 2 and Theorem 3 are for diagonal similarity transformation.
