Application of Matlab in chemical experiment data and model parameters fitting function

Li Benxiang Dong Xinrong Zeng Kui (College of Science Hunan Agricultural University,Changsha,410128,Hunan,China)  
It is often necessary to fit the experimental data into mathematics model in the research of chemical issues so as to describe the relation between independent variable and dependent variable in the procedure or phenomenon quantitatively.Least-square method is one of the major way to acquire model parameters.Several function and using method to acquire the model parameters by means of Matlab are listed in this paper.By way of examples the paper gives a brief introduction to univariable curve fitting,multivariable curve fitting and differential expression fitting.It is showing that by Matlab the fitting of most experimental data can be realized,so that the time spent on experimental data procession can be economized and the precision of the model parameters can he improved.
