摘要
研究两个线性最小二乘问题解流形之间的逼近性。所得结果可看作普通最小二乘问题扰动理论的继续。推广了若干已有结论。
This paper deals with the approximation between the solution sets of two least squares problems. Our results obtained in this paper are developments of the perturbation theory which concerns the unique solution case. Some of the results proved by Ding Jiu, Dupre and Kass are extended.
