摘要
在最小二乘意义下用 GNL法拟合常见的三参数隐函数曲线时 ,用循环搜索法确定了单个未线性化参数初始值 .并成功地以多个著名模型为例对此进行了验证 .
The method of cyclic search is applied to determine the initial values of single non-linearized parameter during the common curves of implicit function with three parameters are fitted in the meaning of least square by means of GNL method. And it is successful to test and verify this algorithm in several famous examples.
