LMS自适应算法，对不同信道参数进行仿真，并输出计算结果(LMS adaptive algorithm, for different channel simulation parameters and output results)

说明：  第17章： 数据统计和分析 MultiLineReg 用线性回归法估计一个因变量与多个自变量之间的线性关系 PolyReg 用多项式回归法估计一个因变量与一个自变量之间的多项式关系 CompPoly2Reg 用二次完全式回归法估计一个因变量与两个自变量之间的关系 CollectAnaly 用最短距离算法的系统聚类对样本进行聚类 DistgshAnalysis 用Fisher两类判别法对样本进行分类 MainAnalysis 对样本进行主成分分析 (data)

In MATLAB, usually we use function bvp4c() to solve boundary value problem (BVP) of ODE. However, we also can use function ode45() to solve BVP of ODE too. However, ode45() needs all initial values at one point. Therefore we have to construct an auxiliary function, whose input argument is the missing initial value and the return output is the given boundary value, Then we can call function fsolve() to get the missing initial value. This method is particularly efficient it the ODE has one or more parameters. Also this method is essentilal for GNU Octave, because whose function bvp4c() is not programmed for parameter ODE yet.

正规化的逻辑回归，可实现图像的分类识别,如人脸识别，数字识别(Logistic Regression with regularisation, can be used for image classification)

说明：  排列熵算法是一种动力学突变检测方法，能够方便、准确的定位系统发生突变的时刻，并且对于信号的微小变化具有放大作用(Permutation entropy algorithm is a dynamic mutation detection method, which can easily and accurately locate the moment of system mutation and amplify the small change of signal)

数学建模比赛训练的代码，里面有matlab软和lingo软件的一些代码(Mathematical modeling training game code, there are some code matlab soft lingo software)

请用多层感知器（MLP）神经网络误差反向传播（BP）算法实现异或问题（输入为，要求可以判别输出为0或1），并画出学习曲线。其中，非线性函数采用S型Logistic函数。(Please use the Multilayer Perceptron (MLP) back propagation neural network (BP) algorithm XOR problem (input is required to determine the output is 0 or 1), and draw the learning curve. Among them, the non-linear function using S-type Logistic functions. )

DCT域的数字水印的嵌入和提取算法，针对的载入原始图像和水印图像都是二值图像(DCT digital watermarking embedding and extraction algorithm for the load are the binary image of the original image and the watermark image)
