摘要
给出了与H -矩阵相关的两个等价性定理 .定理之一陈述了Schur补与原矩阵之间的一个等价条件 .另一定理描述了对角元为正的对称的H -矩阵与它的比较矩阵之间的一个等关系 .
Two equivalence theorems related to H-matrices were discussed.One stated a equivalent condition between the Schur complement and the original matrix.Another described a equivalent relation between the original matrix A being a symmetric H-matrix with positive diagonal entries and its comparison matrix <A>hese properties are new and very useful in many practical applications.
