调用方法：

CurveFitting fitting = new CurveFitting()

double[] xs = fitting.Fitting(xv, yv, n, m)

说明：

拟合函数：double[] xs=Fitting(int[] xval, double[] val, int n, int m) xval:点的横坐标 val:点的纵坐标值 n:欲拟合多项式的最高次数 m:拟合点的个数 数组xs为返回的多项式系数，次数从0到n。如有问题，请发送邮件至gaocongly@126.com咨询讨论-Call the method: CurveFitting fitting = new CurveFitting ()　double [] xs = fitting.Fitting (xv, yv, n, m)　Note: Fitting function: double [] xs = Fitting (int [] xval, double [] val, int n, int m)　xval: point of abscissa　val: the value of the vertical axis point　n: For the maximum number of polynomial fitting　m: the number of fitting points　array of xs for the return of the multi- polynomial coefficients, the number from 0 to n.
