摘要
给出了分块矩阵有定性的一个判据，同时给出了矩阵方程ＸＡ＝Ｂ有定性解存在的充要条件及解的一般形式。
A criterion for the definiteness of the pinioned matrices isPresented, and the neccssny and sufficieat conditions under whichthe solutions for the definiteness of the matrisx equation XA=B existare given, and the general forms of the solutions are also obtained.
