Nonsubsampled contourlet transform

初始采样点对于IEC检测的影响，不加任何窗函数的情况下(The initial sampling point for the IEC test the impact, without any window function case)

matlab 的句柄实现过程及实例解析 (matlab instance handle and resolve implementation process)

说明：  对简单闭环系统的PID控制参数进行优化，得到最佳的控制效果。使用时将该文件夹设为matlab默认文件夹，用simulink打开.mdl文件，在命令行窗口输入.txt文档中命令，可以得到优化后的P、I和D参数。(The PID control parameters of the simple closed-loop system are optimized to obtain the best control effect. With using these codes, the folder must be set as the default folder of matlab, then open the. MDL file, and input the commands of . TXT document in the command line window. The optimized P, I and D parameters will be obtained.)

说明：  参考文件MAT-FILE打包下载visualC加加MATLAB(MAT-FILE)

说明：  主要介绍Matlab的一个函数的使用，如此Matlab(Matlab introduces a function of use, so Matlab)

Ising model 2D simulation

基于粒子群算法的PID控制器优化设计，注释说明清晰，程序运行顺畅(Based on Particle Swarm Optimization Design of PID controller, clear explanatory notes, the program runs smoothly)

开关磁阻电机，直接瞬时转矩控制，速度闭环，三相6/4 SRM Simulink仿真，可用(Switched reluctance motor, direct torque control, closed loop speed, three-phase 6/4 SRM Simulink simulation, available)

pca、svd、mds 数据降维，用来对数据进行预处理 新人学习，叨扰(pca data dimension reduction)
