摘要:

 该文给出了矩阵方程X+AXB=C存在唯一解的充分必要条件和解的表达式,该公式只是ABC的多项式,利用该结果,解决了‖A1XB1-C12F+A2XB2-C22F = min的解的表达式问题.

关键词: 矩阵方程, 矩阵, 最佳逼近

Abstract:

In this paper, we give that a nessary and sufficient condition for the matrix equation X+AXB=C to have unique solution and the expression of unique solution. use the results abut X+AXB=C, we obtain that the expression of best approximation of the A1XB1-C12F +A2XB2-C22F = min.

Key words:  Matrixequaiton, Matrix, Bestapproximation.
