摘要
讨论了一般矩阵的加权Moore-Penrose逆,给出矩阵加权Moore-Pence逆存在的一些充分必要条件,以及它的加权Moore-Penrose逆的刻画和性质。得到了矩阵A的加权Moore-Penrose逆等于A的充分必要条件。
The weighted Moore -Penrose inverses of generalized matrices are discussed. Some necessary and sufficient conditions for existence and some characterizations and properties of the weighted inverses of matrices are given. In particular, the necessary and sufficient conditions of the weighted Moore - Penreze inverse of matrix A equal to matrix of A.
