This is a Simulation for Hysteresis Band PWM Technique for Power COnverters in MATLAB Simulink.

重装系统后恢复matlab文件关联,重装系统后，若没动MATLAB安装目标，则MATLAB不用重新安装。（同样的原因，可以移动MATLAB安装目标）对MATLAB相关文件，建立重新关联就行了。(Reinstall the system restore matlab file association, reinstall the system, if no action MATLAB installation target, MATLAB without having to reinstall. (For the same reason, you can move MATLAB installation target) on MATLAB related files, to establish re-associate on the line.)

利用朴实贝叶斯方法求解有关肺炎的问题。肺炎对应有四个特征：发烧、疼痛、咳嗽和血细胞异常，当确定了患肺炎与否时，四个特征条件独立。假设患肺炎与否和四个特征都可表示为Ture和False。 根据pneumonia.tex文件中的数据（500行，每行前4个数对应4个特征变量，第5个数对应患肺炎是否为真，以0表示False，1表示Ture），编写Matlab 程序 maininference.m，从example.txt中读取病人的症状信息（0表示False，1表示True，-1表示not given），并计算对应的患肺炎的可能性。所给的信息按发烧、疼痛、咳嗽、血细胞异常的顺序排列。将计算结果保存在answer.txt中。(Simple Bayesian method to solve the question of pneumonia. Pneumonia corresponding four characteristics: fever, pain, cough and blood cell abnormalities, determine the risk of pneumonia or not, the four characteristics of conditional independence. Assumptions suffering from pneumonia or not and four features can be represented as Ture and False. According to the data pneumonia.tex file (500 lines, each line of the first four numbers corresponding to the four characteristic variables, number 5 corresponds to the risk of pneumonia is true, 0 represents False, said Ture), to write Matlab program maininference. m from example.txt read the information of the patient' s symptoms (0 = False, said True, the-1 indicates not given), and to calculate corresponding to the likelihood of suffering from pneumonia. The information given by the order of fever, pain, cough, blood cell abnormalities. The calculated results is be saved in answer.txt.)

Reads a ply file (text format). ply files can be in binary format as well this function can read ply files in txt format only e.g. created by makePly.m.

很好用的9节点故障仿真图，本仿真是以matlab中的psat工具箱为开发工具，对感兴趣的同学有一定的参考价值。(Well with the simulation of Figure 9-node failure, the simulation is based on the psat matlab toolbox for the development of tools for students interested in a certain reference value.)

SQP method 的matlab程序代码(programming in sqp method of matlab )

说明：  这是一本关于matlab的教程，同时也是一本信号处理的教程，其特点是将matlab用于信号处理(This is a tutorial on matlab, but also a signal processing tutorial, and its characteristic is used in signal processing matlab)

说明：  采用db1基本小波来分解信号,比较第三层近似信号与原始信号,重构最大误差,比较第三层近似信号与原始信号.(used db1 to the basic wavelet decomposition signal, the third layer approximate comparison with the original signal signal, the largest reconstruction error Comparing the third layer similar to the original signal with the signal.)

通信原理课程的实验，接收机模型。模拟了最佳接收机模型的建立，高斯噪声(Communication- Receiver in matlab.)

自己根据书编的利用遗传算法实现tsp问题的程序(Own program based on the book series of the utilization of genetic algorithm tsp problem)
