摘要
讨论了总体最小二乘法在解病态矩阵中的问题。利用改进后的总体最小二乘迭代算法研究测量平差在病态方程中的应用。实验证明,该算法解决了方程的病态性,且精度与最小二乘方法具有一致性。
The total least squares method in solving ill posed matrix problems is discussed.By which,it also could applicate in ill posed equation survey adjustment by improved total least squares.The experiment shows that ill posed equation could solve in algorithm,and the accuracy is similar with least squares method.
