系统辨识的作业，是自己写的，有需要的可以参考参考(System identification of the work is your own writing, there is a need that can refer to reference)

三相光伏逆变并网的仿真，基于欧几里得距离的聚类分析，基于kaiser窗的双谱线插值FFT谐波分析。( Three-phase photovoltaic inverter and network simulation, Clustering analysis based on Euclidean distance, Dual-line interpolation FFT harmonic analysis kaiser windows.)

有关Matlab课件，效果好值得借鉴，希望大家喜欢(On the Matlab software, the effect is worth learning well, I hope you like)

it is used to remove noise from images

说明：  通信系统的matlab仿真实例,有源代码和仿真图在里面，可供参考(Matlab simulation example communication system, source code and simulation diagram on the inside, for reference)

本文介绍在研究生阶段研究的最新卷积程序，希望有用。(This article describes the stages of postgraduate study at the latest convolution process, seek to help.)

本代码的方法是借助旋转不变技术估计信号参数(Estimation of Signal Parameters via Rotational Invariance Techniques)，现已成为谐波恢复（即正弦波个数及频率估计）的一种主要特征分解法。(This code is to help the estimated ESPRIT signal parameters (Estimation of Signal Parameters via Rotational Invariance Techniques), has now become the harmonic retrieval (that is, the number and frequency sine wave estimated) of one of the main characteristics of decomposition.)

We see that HTH matrix is almost diagonal as the off diagonal elements are nearly zero. So we are getting exact estimation in case of PRN INPUT due to diagonality of HTH matrix. As seen that the unknown inpulse response ( h ) and estimated impulse response ( hth ) are coming out to be exactly same. The estimation even gets better for large N .as we get the HTH matrix perfect diagonal. So we come to know that we can estimate the unknown parameters exactly when PRN input is used.

说明：  自己编写的计算光流场的MATLAB程序，基于梯度的方法，非常简单(I have written a MATLAB calculation of optical flow procedures, based on the gradient method and it is very simple)
