摘要 利用矩阵对的标准相关分解、广义奇异值分解和投影定理,给出了矩阵方程ATXA=B的双反对称最小二乘解的一般表达式,在此基础上,求出了给定矩阵的最佳逼近. According to the canonical correlation decomposition of a pair of matrices, generalized singular Value decomposition and the projection theorem, the expression of the least-squares solutions of anti-bisymmetrie matrices to matrix equation A^T XA = B is given. Based on this result, the optimal approximate solution to a given matrix is also derived.
