主成分分析算法（PCA），这是一个外国人编写的，很具有参考价值(principal component analysis algorithm (PCA), which was prepared by a foreigner, it is very valuable reference)

matlab初学者可以看一看，可以对matlab编程有初步了解。(Matlab beginners can take a look at a preliminary understanding of the matlab programming.)

粒子群优化算法。这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。只有几十行代码。(Particle Swarm Optimization. This program is the most basic particle swarm optimization program using Matlab, very simple. Only a few dozen lines of code.)

matlab源代码，很好的用得 很好的东东哦个(matlab source code, very good with very good Dongdong Oh months)

Classical artificial neural network course information

说明：  简单的评分系统 实现去掉一个最高分与去掉一个最低分然后取平均值的运算(Simple scoring system to achieve the highest score and remove to remove a minimum score and then taking the average of a computing)

层状压电圧磁结构中表面波的传播，表面波分SH表面波和瑞丽表面波(Layered magnetic structure of piezoelectric pressure wave propagation, wave and wave of SH wave Ruili)

数字语音是信号的一种，我们处理数字语音信号，也就是对一种信号的处理，那信号是什么呢？ 信号是传递信息的函数。离散时间信号——序列——可以用图形来表示。 按信号特点的不同，信号可表示成一个或几个独立变量的函数。例如，图像信号就是空间位置（二元变量）的亮度函数。一维变量可以是时间，也可以是其他参量，习惯上将其看成时间。 (Digital Voice is a signal that we deal with digital voice signal, that is, the processing of a signal, that signal what is it? Signal is a function of transmitting information. Discrete-time signal- sequence- can be used to indicate the graphics. According to the different signal characteristics, signal or can be expressed as a function of several independent variables. For example, the image signal is the spatial location (binary variables) of the brightness function. Variables can be one-dimensional time and other parameters can be, habits will be time to treat it as a.)

是用于建模方面的,很有用,所上传的5个程序文件要协同工作才行(Is used for modeling, very useful, 5 program files uploaded to work for the job)

关于CoVaR和Copula的R代码，大部分Copula都可以通过此代码计算对应的CoVaR(You can use this package to estimate the CoVaR based on various copulas)
