摘要
研究了自反矩阵和反自反矩阵反问题的最小二乘解及最佳逼近,给出了最小二乘解和最佳逼近解,并得到丁反问题有解的充要条件及解的表达式。
The least-squares solutions and the optimal approximation for the inverse problem of the reflexive and anti-reflexive matrices are studied, their solutions are given, at the same time, The necessary and sufficient conditions of the inverse problem are drived, the expressions of the solution are provided.
