Symmetric Ortho-symmetric Least Square Solutions of the Matrix Equation A~TXA = B
【摘要】 基于广义奇异值分解定理,我们得到了矩阵方程对称正交对称最小二乘解的表达式,并导出了最佳逼近已知矩阵的对称正交对称最小二乘解和矩阵方程的最小范数解。
【Abstract】 Basing on the generalized singular value decomposition (GSVD) theorem, we derived the least squares expression of the symmetric ortho-symmetric solutions of the matrix equation. The expressions of the optimal approximation solution to the given matrix and minimum norm solution were also derived.
