Actualizing Least-squares Curve-fitting Based on Matlab

WANG Ke ,MAO Zhi-ji(Telecommunication Department,Communication University of China,Beijing 100024,PRC)  
Function relation between physics variables is important in actual research. This paper introduces least squares principle firstly,then introduces the methods and approaches of actualizing Least-squares curve-fitting based on Matlab to gained function relation,finally this paper compares results which are received by different fitting ways through an example.
