摘要
在加入阻尼因子以改善系数阵性质的阻尼最小二乘法 (即Marquardt法 )中 ,选择一个合适的阻尼因子是十分困难的 ,它需要多次求解线性方程组。文中采用改进的Marquardt法进行非线性测量数据处理 ,大大减少了计算工作量。
In the method of Marquardt which adds damping element for making the quality of coefficient matrix better, the most difficult work is to select a suited damping element. This paper gives an improved Marquardt method. It can be applied into our research of observation value adjustment. Compared with Marquardt method, it will enable us to save a great amount of work.
