用递推法产生正交多项式系，即求alpha[j+1]、beta[j] 入口参数：m是数据点数，n是拟合的最高阶数， float x[],float y[]是对应纵横坐标，出口参数：a[] 是最小二乘拟合参数，alpha[]、beta[]是递推系数

基于最小二乘原理的正交多项式拟和输入原始数据及拟和次数即可输出最终拟和表达式系数-based on the principle of least squares orthogonal polynomials and to the importation of the raw data and can be exported and the number of proposed and final expression coefficient

基于非等距节点的正交多项式的最小二乘法拟合算法之程序实现-Nodes based on non-isometric orthogonal polynomial least squares fitting algorithm of the program

给定一组数据 进行最小二乘拟合 包括使用以正交多项式为基底的拟合-Given a set of data, including the use of orthogonal least squares polynomial fitting for the basement
