摘 要 :伴随着测量事业的发展 ,要编制测量参数估计的矩阵运算程序越来越复杂 ,难度也越来越大。MATLAB 与其他编程

语言相比 ,具有简单直观、速度快等特点。本文将 MATLAB 语言运用于非线性模型参数估计 ,并给出了单纯形法进行非线性

Abstract :With the development of surveying project , it has become more complex and more difficult to design a program for parame2

ter estimation to deal with matrix operation. Compared with other arithmetic language , MATLAB has characters of simple and di2

rect program and high speed of operation. In this paper , it is described that how MATLAB software is applied to parameter estima2

tion of nonlinear models. What is more , the function of simplex search to estimate the parameter of nonlinear models is given.

Key words :Matrix Laboratory ; least squares parameter of nonlinear models ; simplex search
