qpsk仿真系统框图，实现四项调制系统仿真实验。(qpsk diagram of simulation system to achieve four modulation system simulation experiments.)

异步电机矢量控制模型，包裹调速等 (Vector control induction motor model, speed control, such as parcel)

说明：  采用混沌和小波相结合的方式实现的图像加密matlab程序(Using chaos and wavelet methods to achieve a combination of image encryption matlab program)

说明：  主成分分析算法，用于建立主成分分析模型，采用累计贡献率的方法(pca )

这个是对PL-logdist和PL-lognormal的一个仿真。程序简单易懂，但是意义不小。有专门的画图子程序。(This is a PL-logdist and PL-lognormal a simulation. Procedures are simple, but the meaning is not small. Have a special drawing routines.)

单面全矢动平衡，萨拉过后而后感觉请啊饿哦韩国(Single vector dynamic balance, and then feel hungry oh please South Korea after Sarah)

pak msk gmsk的性能比较.功率谱以及误码率的比较，可以出图。(psk msk gmsk)

最新飞行程序设计，具体的编码过程与结果描述。(The latest flight program design, concrete description coding process and results. )

本文介绍了如何利用excel link实现Excel与Matlab混合编程。通过连接Excel和Matlab，用户可以在Excel工作表空间和宏编程工具中使用Matlab的数值计算，图形处理等功能，不需要脱离Excel环境。(This article describes how to use excel link Excel and Matlab achieve. By connecting Excel and Matlab, Matlab users can use the numerical calculations, graphics and other functions in an Excel worksheet and macro programming tool space, without departing from the Excel environment.)

这是一个用matlab实现的人脸识别的pca方法，正确识别率不错。(err)
