On criterion for the definiteness of portioned matrices Ⅱ

    摘要
  • 摘要: 给出了分块矩阵有定性的一个判据以及矩阵方程XA =B有定性的解存在的充要条件和解的一般形式

     

    Abstract: A criterion for the definiteness of the portioned matrices is presented,and the necessary and sufficient conditions under which the solutions for the definiteness of the matrix equation XA=B exist are given,and the general forms of the solutions are also given.
