返回系数估计向量；stats返回各种参数估计；’wfun’指定一个加权函数；tune为调协常数；’const’的值为’on’(默认值)时添加一个常数项；为’off ’时忽略常数项(Return coefficient estimate vector stats back to a variety of parameter estimation ' wfun' to specify a weighting function tune for the co-ordination constant ' const' value ' on' (default value) add a constant term for the ' off' time ignore the constant term)

从曲线中检测到其峰值：先利用二次求导得到所有凸点，设置门限，去除过低的凸点，然后利用滑动窗的方法，在凸点中求得满足峰值要求的点(Detected from the curve to its peak: the first use of the second derivative method to get all the bumps, set the threshold too low to remove the bumps, and then use a sliding window, obtained in a bump to meet peak requirements of point)

金融数量分析 有关均值方差分析还有收益率波动问题的代码(Financial quantity analysis The mean variance analysis and yields fluctuation of the code )

计算了沿CMPL厚度方向，可以看出，CMPL的界面从第一个网格移动了1/4个网格，这是为了保证，CMPL更新的电场和磁场的数目相同。(The thickness direction along CMPL is calculated.It can be seen that the interface of CMPL moves 1/4 of the grid from the first grid to ensure that the number of electric and magnetic fields updated by CMPL is the same.)

这个软件主要用Bayes分析肺癌的早期诊断，早在X光片也无法确定时用先验分布计算后验分布概率，估计对医生有些实际价值。(This software is mainly used Bayes analysis of lung cancer, early diagnosis, early X-ray films can not be used to determine the prior distribution when calculating the posterior distribution of probabilities, it is estimated that some practical value for doctors.)

说明：  用有限差分法解一维定态薛定谔方程的5个最小的本征值(Calculate the first five normalized eigenfunctions and eigenvalues using a direct method.)

前推后代潮流计算 把节点按不同类型定义为三类节点，方便计算(Forward offspring flow calculation node according to the different types of definitions for the three types of nodes, to facilitate the calculation)
