A General Data Fitting Method Based on MATLAB

Song Xiao-xi

Abstract

This paper introduces a general data fitting method based on MATLAB in some applications, such as experimental data processing and statistical data analysis. Firstly, a general polynomial data fitting method is designed. Then we illustrate that the rule of this fitting method is the least square method and its theory support is the function approximation theory. Finally two specific examples are used to verify thee ffectiveness and generality of the proposed fitting method.
