一类约束矩阵方程的可解条件与最佳逼近问题
The solvability conditions for a kind of constrained matrix equation and relevant optimal approximate problem
摘要
Abstract
By use of the decomposition theory of a space and the singular value decomposition of a matrix, some necessary and sufficient conditions for the solvability of the matrix equation AX+ BY = Z in matrix set Crn×n(P,Q) × Can×n(P,Q) are provided, the general representation of the solutions is derived for a solvable case. The expression of the solution for the corresponding optimal approximation problem is given anda perturbation of the solution (A,B) is analyzed.关键词
