2个复矩阵若干广义逆的结构表达式及其块独立性

摘要

By the well-known quoient singular value decomposition( Q - SVD) ,we derive the structural representation for the generalized inverses of two matrices, and present corresponding necessary and sufficient conditions for the block independency of two matrices under two different definitions.%利用Q - SVD分解,得到了2个矩阵广义逆的结构形式,并且在两种定义下分别给出了2个矩阵块独立性的充要条件.
