说明：  高斯光束matlab源程序，可以编译修改。(Gaussian beam matlab source, can compile changes.)

说明：  用MATLAB实现数字图像的傅里叶变换，显示图像频谱(Digital images using MATLAB Fourier transform, display the image spectrum)

matlab中有很多特殊符号需要表示，本文列出了常用的希腊字符的表示方法(Matlab has many special symbols need to say, this is a list of the commonly used method of Greek character says)

Matlab code for for Fourier Transform

matlab程序，经过多次调试可以运行，包含多个文件，可以准确得到结果。(matlab program, after several debugging can run, contain multiple files, you can get accurate results.)

介绍信号与系统分析的内容并应用matlab实现(The introduced signal and system analysis and application of matlab)

基于matlab环境编译的创建人脸数据库，特征提取，人脸识别源码程序，运行时识别率较高。( based on MATLAB environment， creates face database, Feature extraction ，face recognition program,having a high recognition rate)

说明：  matlab图形用户界面设计教程，像vc一样进行交互(tutorial matlab graphical user interface design, just as interactive as vc)

说明：  单级倒立摆的稳定控制，实际上是一单输入多输出系统的稳定控制。此时系统输入是电机控制电压u，输出是倒立摆竖直方向角度 和旋臂位置 。对方程(2.5)进行变形即得 与u 之间的输入输出方程,很明显,它是一个不稳定的二阶系统(Single inverted pendulum stability control, is actually a single-input multiple-output system stability control. At this point the system is a motor control input voltage u, the output is inverted pendulum angle and vertical position of spiral arms. Of the equation (2.5) for deformation of the gain and input-output equation between u, obviously, it is an unstable second-order system)
