3D姿态识别的adaboost代码，使用matlab语言编写(A Study of AdaBoost in 3D Gesture Recognition)

利用python实现基于用户的协同过滤推荐，采用pearson相关系数计算相似度，加权平均预测分数(Users use python-based collaborative filtering recommendation, pearson correlation coefficient is calculated using the similarity, the weighted average prediction scores)

此函数用来演示自动控制系统中的饱和非线性特性的描述函数 此函数是要调用输入的A矩阵中的元素 输入变量a，k的含义分别为：(This function is used to demonstrate automatic control system of the description of the saturation nonlinearity function this function is to call the input of the A element in the input variables a, k means are:)

说明：  四阶龙格—库塔算法。自己在课程设计中就是用的这个算法。对于初学者有一定的帮助(Fourth order Runge- Kutta method. Own course design is to use this algorithm. Be helpful for beginners)

本文档主要实现ccsk编码和解码功能，主要实用于数据通信中(This document is intended to achieve ccsk encoding and decoding functions, mainly useful in data communications)

说明：  模拟缉私船追击变速走私船 加速到一定的速度，经过多久追上 并画出轨迹图！(Simulate how long it takes for the anti-smuggling vessel to chase the variable speed smuggling vessel to accelerate to a certain speed and draw the trajectory chart!)

最大流问题的算法，思路清晰，很值得收藏。大家赶快下载(Algorithm for maximum flow problem is clearly thought worthy of collection. U.S. soon to download)

matlab源程序，可以仿真出来经典的BA无标度网络模型(Matlab source, can be simulated classic BA scale-free network model)
