电力系统中由于采用了很多电力电子设备，引入了大量谐波，致使电能质量降低，改程序可以求出谐波的幅值，频率和相位(Spectrum analysis)

LFM信号的分数傅里叶变换分析，包含LFM信号分数阶谱图产生及FrFt子程序，及峰值搜索。非常好(LFM signal s fractional Fourier transform, including the LFM signal generation and FrFt fractional spectrum of subroutines, and peak search. Very easy to use.)

使用MATLAB编写的一种简单的自适应滤波程序(Using a simple adaptive filtering program written in MATLAB)

说明：  VMD是通过迭代搜寻变分模型（具体怎么搜寻，请亲们自己看，我主要讲他的大概）最优解， 来确定我们所知的模态uk(t)及其对应的中心频率ωk和带宽。 每个模态都是具有中心频率的有限带宽（就是在频域中有在一定的宽度）。所有模态之和为源信号。(VMD is to determine the modal UK (t) and its corresponding central frequency, k and bandwidth by iteratively searching for the optimal solution of the variational model (see dear friends for details, and I will mainly talk about his approximate solution). Each mode is a finite bandwidth with a central frequency (that is, a certain width in the frequency domain).The sum of all modes is the source signal.)

用递推最小二乘法进行系统辨识，包括simulink环境下搭建模型以及源代码(recursive least square （RLS）source code)

使用线性回归的方法进行预测、训练，适合初学者使用(Using linear regression method to predict training for beginners)

MATLAB程序代码，对人数进行统计，对图像灰度进行处理。(MATLAB program code, statistics on the number, carries on processing to the image gray.)

用椭圆低通滤波器对语音信号进行滤波处理，实现降噪处理(The elliptic low pass filter is used to filter the speech signal, and the noise reduction processing is realized.)
