中文说明：首先进行数据的归一化，然后计算相空间中第M点与各点的距离，再排序计算相空间中第M点的(m+1)个参考邻近点，再计算第M点的(m+1)个参考邻近点的权P[i]， 再用最小二乘法计算a[],b[]
English Description：
Normalized data first, then the phase space m and distance of each point, then sort the calculation in phase space m (m+1), a reference to neighboring points and then calculate m (m+1), a neighbouring right P[i], then using least squares method to calculate a[],b[]
