摘要
在最小二乘意义下用 Gauss-Newton法拟合三参数双指数曲面z =γ[exp( -αx) +exp( -βy) ]时 ,充分利用观测值 ,应用循环搜索法确定了参数初始值 .并成功地以由 Meyer &Roth给出的观测值为例对此进行了验证 .
The method of cyclic search is applied to make full use of observe values to determine the initial values of 3 parameters during double exponential surfacez=γis fitted in the least square meaning by means of Gauss-Newton method. And it is successful to test and verify this algorithm in the example which observed values were given by Meyer & Roth.
