说明：  适用于三维体结构的拓扑优化，基于simp方法的matlab代码(Topology optimization for 3D structure)

计算三大相关性系数（pearson、spearman、kendall）copula函数族检验(The family of three correlation coefficients (Pearson, Spearman, Kendall) copula is calculated.)

Linux下SPI转USB驱动，基于沁恒ch374芯片(Linux SPI USB driver based on ch374 chip)

一个简单的计算hurst指数的matlab程序(A simple calculation of Hurst index of matlab program)

说明：  K近邻算法。(k-Nearest Neighbor，KNN)，是一个理论上比较成熟的方法，也是最简单的机器学习算法之一。该方法的思路是：在特征空间中，如果一个样本附近的k个最近(即特征空间中最邻近)样本的大多数属于某一个类别，则该样本也属于这个类别。(K-nearest neighbor algorithm. K-nearest neighbor (KNN) is a mature method in theory and one of the simplest machine learning algorithms. The idea of this method is: in the feature space, if most of the k nearest (i.e. the nearest) samples near a sample belong to a certain category, then the sample also belongs to this category.)

1、时间序列的ARMA（自回归移动平均）算法代码实现； 2、能用于平稳时序的分析和预测； 3、使用C/C++开发。(1、The codes relization of timeseries arma forecast method 2、Be used in analyzing and forecast in timeseries 3、Be developed by C/C++ tool.)

说明：  这是个非常好用的实验，主要是差分放大带电路，和负反馈放大电路(The substitution of some rolling friction for sliding friction results in a very considerable reduction in friction.)

此程序实现了三个食人魔和三个传教士的过河问题，其中船上最多只能载两个人，船上和两岸的传教士数大于食人魔数传教士才是安全的-Realize this procedure three Ogre and three missionaries across the river, which can only be set on board a maximum of two people on board and on both sides of Ogre missionaries more than a few missionaries are safe
