说明：  有关于滑模变结构的S函数的例程2，用来学习S函数结构(About SMVSC S-function routines 2, S-function structure for learning)

IIR filter synthesis algorithm with almost linear group delay

霍夫曼编码，随机生成10个概率，和为1，用霍夫曼编码输出，采用map函数(Huffman coding, the probability of a randomly generated 10, and 1, with the Huffman code output, the use of map functions)

用于计算电位。采用有线差分法迭代实现。显示出图像(Used to calculate the potential. Difference method using an iterative wired.)

说明：  运用各种机器学习算法，检测人脸是否为照片(Various machine learning algorithms are used to detect whether a face is a photo)

适用于本人开发的抽号器WindowsFormsAppkication.rar。 可以运行后在in.txt中第一行输入总人名数，之后从第二行开始，每一行输入一个人名。之后运行程序（eze等同于exe），会生成Form1.cs，用记事本打开后复制到原Form1.cs进行替换。可以应对多种情况。(I developed suitable for pumping number is WindowsFormsAppkication.rar. After the run in the first row in.txt enter the total number of names, and then start from the second row, enter a name for each row. After running the program (eze equivalent exe), will generate Form1.cs, copy after use Notepad to open Form1.cs to replace the original. You can respond to a variety of situations.)
