厌倦了使用大型库，比如OpenSSL，

应用背景功能强大的Matlab零相移数字滤波器filtfilt函数的C语言实现。数字信号处理非常有用的哦关键技术滤波器的频率响应由幅度响应和相位响应两部分组成，在信号处理的某些场合中, 希望设计的滤波器的相位响应能够严格为零。那就要用到Matlab的这个函数，这里将Matlab语言翻译了为C语言。主要就是一些矩阵的运算，高等数学的知识

FaceDetection是一个静态人脸检测程序，注意FaceDetection需要OpenCV提供的库支持， 因此请首先到相关网站上下载并安装OpenCV， 此外本程序需要导入一个分类器文件haarcascade_frontalface_alt.xml， 该文件在OpenCV中提供，请将该文件复制到程序同一目录下，程序即可正确运行。

应用背景 Fifty Years of Shannon Theory： A brief chronicle is given of the historical development of the central problems in the theory of fundamental limits of data compression and reliable communication. 关键技术Shannon’s A mathematical theory of communication”published in July and October of 1948 is the Magna Carta of the information age. Shannon’s discoveryof the fundamental laws of data compression and transmission marks the birth of Information Theory. A unifying theory with profound intersections with Probability, Statistics, Computer Science, and other fields, Information Theory continues to set the stage for the development of communications, data storage and processing, and other information technologies.
