说明：  旋转式永磁同步电动机的电压矢量PWM控制算法，可以作为比较参考。(Rotating permanent magnet synchronous motor voltage vector PWM control algorithm can be used as comparison reference.)

关于kmeans 的算法，和如何验证匹配准确率的算法(About kmeans algorithm, and how to verify the accuracy of the algorithm matches)

code for data preproccess in 3 steps :Swap lines with missing value NaN, zscore Normalization, Standardization process

matlab code for envelope detector for analog communications.

说明：  首先，对复杂振动信号进行EMD分解，得到各个频率分量，接着，对各分量进行Hilbert变换，得到瞬时频率(END resolve,hilbert chang,evry imf,instantaneous frequency)

本程序是用于图像去噪，使用的是多小波GHM去噪方法，对比单小波去噪效果明显。(This procedure is used for image denoising, the use of multi wavelet GHM denoising method, compared to Dan Xiaobo denoising effect is obvious.)

说明：  his work proposes two novel optimization algorithms called Salp Swarm Algorithm (SSA) and Multiobjective Salp Swarm Algorithm (MSSA) for solving optimization problems with single and multiple objectives. The main inspiration of SSA and MSSA is the swarming behaviour of salps when navigating and foraging in oceans. These two algorithms are tested on several mathematical optimization functions to observe and confirm their effective behaviours in finding the optimal solutions for optimization problems.

说明：  用于变量的降维，是目前为止最好的降维方法，是比较常用的降维方法之一。(For variable dimension reduction)

最小二乘支持向量机的一个小程序，非常简单，也很耗用(Least Squares Support Vector Machines, a small program, very simple and consumption)

这是一个用matlab做的绘制正弦和余弦图像的程序，是用m语言写的。(This is a matlab to do with sine and cosine image rendering procedures are written m language.)
