摘要
利用矩阵的奇异值分解及标准相关分解,建立子矩阵约束下双中心矩阵反问题解存在的充分必要条件,并给出了通解的表达式.进而得到了对任一给定矩阵的最佳逼近.
Using the singular value decomposition (SVD) of a matrix and the canonical correction decomposition (CCD) of matrices, this paper establishes the necessary and sufficient conditions for the existence of the doubly center solutions and presents the expressions for the inverse problem of a matrix under a submatrix constraint. Moreover, the optimal approximation problem to a given matrix in the solution set is considered, and the optimal approximation solution is obtained.
