| Abstract: | With the development of surveying project, it has become more complex and more difficult to design a program for parameter estimation to deal with matrix operation. Compared with other arithmetic language, MATLAB has characters of simple and direct program and high speed of operation. In this paper, it is described that how MATLAB software is applied to parameter estimation of nonlinear models. What is more, the function of simplex search to estimate the parameter of nonlinear models is given. |
