此程序为matlab的关于辐射增强的一段代码，已经用于开发的软件中(This procedure matlab section on the radiation code has been used to develop the software)

说明：  本程序是在MATLAB环境采用ADABOOST算法实现手势识别。(This program uses AdaBoost algorithm to realize gesture recognition in Matlab environment.)

Generates a noise parameter

Matlab M-Files:There are four ways of doing code in Matlab. One can directly enter code in a terminal window. This amounts to using Matlabas a kind of calculator, and it is good for simple, low-level work. The second method is to create a script M-fi le. Here, one makes a fi le with the same code one would enter in a terminal window. When the fi le is “run”, the script is carried out. The third method is the function M-fi le. This method actually creates a function, with inputs and outputs. The fourth method will not be discussed here. It is a way to incorporate C code or FORTRAN code into Matlab this method uses .mex fi les. We will not disucss it here.

本程序用来模拟当前研究很热门的自旋阀满足的LLG方程，并作图研究其性态。具体数据公式文件包里有详细说明(the procedures used to simulate the current research is very popular spin valves to meet the LLG equation, and mapping study its behavior. Specific data document bundle formula are described in detail)

Matlab 数学工程应用，对想用matlab编程的人是一个非常好的东东(matlab math project apply)

采用蚁群算法求取TSP问题 1基本原理： 本质上也是一种概率算法，通过大概率收敛到最佳值，和其他的智能算法很相似。蚁群分泌的信息素存在正反馈，使得较佳的解具有大概率被选到，当全局都选用较佳的解，变可以得到整体的最优解。 2几个关键点：  1）概率选择：受信息素浓度和启发函数影响，启发函数为距离的倒数   2）信息素挥发：考虑到信息素随时间的挥发，加入挥发因子  3程序设计步骤：  1）初始化各个参数：包括各点的距离，信息素的初始浓度，蚂蚁数量，信息素挥发因子，信息素和启发函数的重要度因子，启发函数，最大迭代次数，路径记录表等等 2）迭代：对每个蚂蚁随机制定初始值，再根据概率选择，选择出每只蚂蚁的路径，确定每只蚂蚁的路径总长度，以及蚁群的最佳路径长度和平均长度，并对信息素进行更新。   3）展示：展示出最佳路径，以及最佳路径对迭代的变化图  4Matlab代码 程序说明：采用蚁群算法求取TSP问题，共有34个城市，从txt文件加载数据： 运行结果：

Ucsd编写的matlab的GARCH模型分析与预测。包括两个安装包和安装说明（各种matlab版本都有），很详细。主要是好多网上其他无法运行，这个步骤我刚刚试试过，可以运行，(UCSD matlab prepared the GARCH model analysis and forecast. Includes two installation package and installation instructions (there are a variety of matlab version), in great detail. Is mainly a lot of other can not run the Internet, the steps I have just had a try, you can run,)
