解决非线性最小二乘问题的两种方法

Two methods solving non-linear least square problem

给出非线性最小二乘问题的两种计算方法,利用非线性最小二乘法处理化学过程产量问题,得到非线性估计参数。结果表明:非线性最小二乘法收敛性较好,残差平方和较小。

In this paper,the author gives two kinds of calculation methods on non linear least square problem.The output problem in chemistry process is solved and non-liner least estimation parameters are got by applying non-liner least square method.The result shows not only clearly good convergence of non-iner least square method,but also little residual square sum.
