在matlab 2012a 下，将一段avi视频分割成序列帧，并保存。程序比较简单，就是用到了VideoReader(In matlab 2012a under the avi video into a sequence of frames, and save. Procedure is relatively simple, it is used in the VideoReader)

排队系统仿真,考虑一个排队系统，顾客到达后，若无空闲服务台则等待，否则接受服务后离开。仿真目的是统计服务台前的平均队长和服务台的忙闲程度。要求能利用离散事件系统仿真的方法对该系统进行仿真，系统的规则和参数自定。(queue up system simulation)

PID解耦，用于多变量解耦，是个很好的例子，希望对大家有用(PID decoupling, for multi-variable decoupling is a good example, in the hope it would be useful)

用于圆形金属波导模式求解，得到特征方程的根，可设定误差范围。(Circular metal waveguide model for solving the characteristic equation has been the root of error range can be set.)

基于SVM的混沌时间序列分析 把SVM优化算法用于混沌时间序列分析 可以得到优于一些方法的结果(SVM-based chaotic time series analysis of the SVM optimization algorithm for chaotic time series analysis methods can be superior to the results of)

说明：  智能天线方向图——波束形成最小均方(LMS)算法(Smart antenna pattern- beam forming least mean square (LMS) algorithm)

用G-N法求解非线性最小二乘优化问题 用修正G-N法求解非线性最小二乘优化问题 用L-M法求解非线性最小二乘优化问题 (GN method for solving nonlinear least squares optimization problems using a modified GN method for solving nonlinear least squares optimization problems using LM method for solving nonlinear least squares optimization problem)

比较有名的matlab图像处理工具包，常见的一些图像处理功能里面都有，该工具包是一位从事计算机视觉研究的人写的，很好用，用起来也很方便(More famous matlab image processing toolkit, some common image processing functions which has the toolkit is a person engaged in computer vision research to write good use, and very convenient to use)

这个函数提供灰度拉伸功能，输入图像应当是灰度图像，但如果提供的不是灰度图像的话，函数会自动将图像转化为灰度形式。x1，x2，y1，y2应当使用双精度类型存储，图像矩阵可以使用任何MATLAB支持的类型存储。(This function provides a gray scale stretching function of the input image should be grayscale image, but if not provided, then gray image, the function will automatically be converted to grayscale image form. x1, x2, y1, y2 should use double precision storage, image matrix can store any type of MATLAB support.)

说明：  用Matlab/simulink所实现的bpsk性能仿真系统，信道为AWGN信道。运行后，可以看到经过bpsk以后信噪比的增益。(using Matlab/Simulink BPSK achieved by the performance simulation system for the channel AWGN. After the operation, we can see the future through BPSK SNR gain.)
