利用聚类算法实现的分类小程序，简单实用，很容易就可以提取出聚类算法，绝对无误运行。(Clustering algorithm using the classification of small program, simple and practical, it is easy to extract the clustering algorithm, is absolutely correct operation.)

说明：  控制安捷伦矢量信号源，在本地计算机上产生一个信号然后传入信号源，本代码含若干练习性的源代码，结合自己大量的调试经验，在signal1.m中对初学者甚至经常使用的用户极易犯得错误进行了详细标注，(Matlab generate data in the waveform file, downloaded to the Agilent signal sources. By reading it, you will get a lot.)

二维图像的读取，辨认，分析，并且用神经网络进行，判定哪些图片可以归为一类(Two-dimensional image reading, identifying, analyzing, and using neural network to determine which pictures can be classified as a class)

自己编写的polar码 编译码算法程序 matlab 可用(polarcode matlab)

对固定结构的网络结构进行线路损耗的计算。简单方便(The line loss of fixed structure network is calculated. Simple and convenient)

将一个m文件转成c /cpp文件并在VC中进行编译。这种方法有个烦人的地方，每次你都需要把matlab生成的一 大堆c和h文件考到vc中，比如我读入一副图片先做膨胀，再腐蚀，再进行小波变换，最后 显示。这样一个程序会生成大概150多个文件，每次都要拷贝这些文件很不方便。我试着用 了另外一种方法，可以简化这些工作。那就是不生成cpp文件交给VC去编译，而是直接在m atlab中生成一个dll交给VC去链接即可。这样无论matlab生成多少文件，都只需要拷贝三 个文件即可。 (m to a document conversion c/cpp files and compile VC. Such a method is a nagging place every time you need Matlab has generated a lot of c and h vc document examination, for example, I read a photo, first expansion, and corrosion, further wavelet transform, the last show. Such a procedure will probably generate more than 150 documents, each copy of these documents must be very inconvenient. I tried another kind of approach can simplify their work. It is not generating cpp documents to the VC to compile, but m atlab directly in the formation of a dll to the VC to link. No matter how many documents generated Matlab, only three need to copy documents.)

MATLAB在信号处理中的应用举例 三角波或锯齿波发生函数： sawtooth() 方波发生函数： square()? 常用窗的MATLAB函数表示(MATLAB in signal processing applications, for example triangular or sawtooth wave generating function: sawtooth () square wave generating function: square () ? window commonly used MATLAB function)

三水新安江模型Matlab的m文件，可运行。运行时自己先找好数据，然后放在同一个文件夹。(The Sanshui Xin anjiang model Matlab m-files can be run. Run-time to find a good data, and then placed in the same folder.)

该模型是模拟信号数字传输系统，可以把一个模拟信号通过PCM编码译码，信道2FSK编码译码，再通过一个二进制对称信道，可以恢复出原模拟信号(The model is the analog signal digital transmission system, an analog signal by the PCM codec, channel 2FSK codec, and then through a binary symmetric channel, you can restore the original analog signal)

Download the file town .jpg, which is a 1024×768, 256-grayscale image taken on a bright sunny day. The image was taken in the shadow of a building. As the result, the sunlight areas are glaring white and the shadow areas are dark and low contrast. Using the image enhancement techniques covered in class, increase the contrast and the brightness of the dark areas, and reduce the brightness of the sunny areas
