摘要
利用矩阵对的商奇异值分解,给出了线性流形上矩阵方程ATXA=B存在中心对称解的充要条件及其通解的表达式.另外,导出了线性流形上矩阵方程的解集合中与给定矩阵的最佳逼近解的表达式.
Using the quotie conditions for the existence and linear manifold are established nt singular value decomposition(QSVD) of matrix pairs, the necessary and sufficient the expressions for the centro-symmetric solutions of matrix equation A^TXA = B on the In addition, in the solution set of corresponding equation, the expression of the optimal approximation solution to given matrix is derived.
