em algorithm - Find approximate solution to Sf = conv(s,f) = d using EM iteration. EM seeks to minimize the Poisson negative log likelihood function J(f) = sum_i {[Sf]_i - (d_i + sigma^2)*log([Sf]_i + sigma^2)}.

针对多径信道的信道均衡，演示了几种经典的算法。可以直接运行。画图时是动态的，做得很精细。(Multipath channel for the channel equalization, demonstrate several classic algorithms. Can be directly run. Paint is dynamic, so very fine.)

说明：  求解分岔问题，非常适合于求解非线性振动问题(Solving bifurcation problems)

MATLAB的一些操作命令，自己总结的一些常用命令，包括PPT，WORD各种格式都有(Some MATLAB command)

matlab程序，调频脉冲波雷达回波信号检测到速度信息(Radar Speed ​ ​ program)

对N个样本点进行主成分分析，并将结果可视化(N sample points on principal component analysis and visualization of results)

说明：  matlab灰色预测模型代码，仅供参考，非原创。(Grey-forecasting model code,for reference only,not original.)

F聚类算法（mathematica），简单实用，无数据(F clustering algorithm (mathematica), simple, practical, no data)

说明：  这些MATLAB的M文件分为两部分：程序清单A中收录了产生PPM-TH和PAM-DS这两个信号源的所有函数；程序清单B中收录了加性高斯白噪声（AWGN）信道建模，正交和非正交单脉冲PPM-TH接收机结构，以及反极性PAM-DS单脉冲接收机结构仿真所需的所有函数。(The MATLAB M-file is divided into two parts: A list of procedures in the collection of produce PPM-TH and PAM-DS two signal sources all functions Listing B, contains an additive white Gaussian noise (AWGN) channel construction mode, orthogonal and non-orthogonal single-pulse PPM-TH receiver structure, as well as anti-polarity PAM-DS receiver structure simulation of single-pulse all the necessary functions.)

this code is of median filtering. this code is only for 3x3 window.
