Counter Seeking parameters and Curve Fitting

Sun Yunyu (Department of Basic Sciences)  
This paper presents a new method for fitting a curve.This method takes the givcn set of points(xi,yi)i=0,1..., n as observed values of the solution of a second order linear ordinary differential equation with unknown parameters,then uses the cubic splines with undctcrmined boundary values as well as the least-square method to determinc thew paramctcrs in the equation.Finally,the solution of the Cauchy problem is taken as the fitting curve.This method can be considered as a significant improvement of model GM(2,1)in[1].Computational results show that it is a good fitting method with high prccisions.
