One program to simulation light passing through a glass sphere. It is interesting and can be used in geometric optics.

matlab let工具箱，Lyapunov的计算(matlab let toolbox, Lyapunov Calculation)

说明：  这个模型可以在MATLAB中，为数据库的进入，提供时间倒数，以防止过多地试密码，从而提高系统的保密性( TIMEOUT = LOGINTIMEOUT(FIRSTARG,SECONDARG) returns the current value of time allowed for a connection to a database to be successful. FIRSTARG, an optional argument, is a string that specifies the JDBC driver to be used establishing the database connection. SECONDARG, an optional argument, is an integer that specifies the length of time the driver will attempt to make a connection to a database. If FIRSTARG is not specified then the default JDBC/ODBC bridge is used to establish the connection to the database. If function is used without arguments then the current time out value is returned. )

说明：  利用小波包变换对一个二维含噪图像进行分析处理。(using wavelet transform packets of a two-dimensional images with noise analysis.)

利用S函数的PID解耦控制器实现单元机组解耦控制(The use of S function decoupling PID controller to achieve decoupling control unit)

说明：  基于matlab的人脸识别程序，可以实现简单的人脸识别功能，算法基于LDA（linear discriminant analysis）(Matlab-based face recognition program, you can achieve a simple face recognition algorithm based on LDA (linear discriminant analysis))

说明：  matlab 6.x的使用指南，较为详细的介绍了matlab 6.x的使用及编程(matlab 6.x use guide describes in detail the use and programming matlab 6.x)

说明：  相干增强扩散，可用于去噪，去噪的同时可较好的保持边缘特征 (failed to translate)

用MATLAB实现SOM算法改进，非常实用的程序！可以直接使用的！(SOM algorithm using MATLAB to achieve improvements, a very useful program! Can use!)

目标跟踪，程序利用卡尔曼滤波器实现了对机动目标的跟踪。效果较好的运动模型。 (Target tracking, procedures realize the use of Kalman filter for maneuvering target tracking. Better model of the movement.)
