LEAST SQUARES HAMILTONIAN SOLUTION OF THE MATRIX EQUATION AXB=C
【摘要】 对于任意给定的矩阵A∈Rk×2m,B∈R2m×n,G∈Rk×n,本文利用投影定理,矩阵对的广义奇异值分解(GSVD),标准相关分解(CCD),研究矩阵方程AXB=C的最小二乘Hamilton解,得到了解的表达式.并由此考虑了解集合对给定矩阵的最佳逼近问题.
【Abstract】 For given matrices A,B and C,we derive the expressions of the least squares Hamiltonian solutions of the matrix equation AXB=C by using the projection theorem,the generalized singular value decomposition and the canonical decomposition.In addition,for given matrix, the best nearness matrix to the solution set is also considered.
