说明：  有关学习MATLAB的WORD文档，很全，在我刚学习MATLAB的时候给了我很大帮助，希望也能帮助大家(MATLAB-WORD documents about learning, it is all in my time just to learn MATLAB gave me great help, hope that we can help you)

说明：  matlab小波包去噪举例，对初学者很有用的一个短程序(matlab wavelet packet denoising for example, very useful for beginners a short program)

本程序适用于论文Robust Sparse Coding for Face Recognition(this code is for Robust Sparse Coding for Face Recognition)

电力线通信多径信道模型-Manfred Zimmermann模型，多径效应的传递函数H(f)可以用N条传输路径的叠加以及含有频率f、延时τ、距离d的方程来表示： H(f)=∑g_i *A(f,d_i )*e^(-j2πfτ_i ) 式中，i 为路径号， g_i为路径 i的加权系数(包含了传输系数和反射系数的作用)，A(f,d_i )为衰耗，其大小由长度、频率决定，τ_i是每条路径上的延时。 (Powerline Communication multipath channel model-Manfred Zimmermann model)

本程序给出了从背景中分离出行人的matlab源代码.采用提取好的背景和行人的HOG特征,而这些特征又分为未分块和分块两组,所谓分块就是将图片进行细分,提取的特征更细.最后用最小欧氏距离法分类.(This procedure gives the background to separate from the travel people matlab source code. By extracting a good background and pedestrian HOG features, and these features are not divided into blocks and blocks Liangzu, the so-called sub-block is to carry out detailed pictures points, the extracted features more detailed. Finally, the smallest Euclidean distance classification.)

As we know, the energy needed for sensors should be electrical. So the rst step before start to work is to convert environmental energy to electrical one. Inside the node there are dierent components for sensing the area, collecting data and processing the data. So the main dierent part of this kind of nodes, in compare of WSN nodes, is the power part. Once the stored energy reach to a certain amount, the power supply for micro controller and transceiver will start to work. They will continue to work until they have energy, as soon as the energy nish, they stops and energy storage device start to work to save energy again. The other fact should be consider about EH-WSN node is that the available energy can change in dierent nodes. So every node has its own harvesting rate.

L-M(Levenberg—Marquardt)是一种非线性最优化里面最常用的方法之一，改方法能快速而准确的逼近收敛值。本文简述了改方法的操作原理和具体运用，如可以方便的用于有约束与无约束最优化的求解。本文件里面有源码和测试码以及对该方法的具体介绍PDF文件。欢迎下载。(L- M (Levenberg- Marquardt) is a kind of nonlinear optimization inside one of the most commonly used method, change method can fast and accurate approximation convergence value.This paper briefly describes the operating principle of change method and concrete application, such as easy to solve constrained and unconstrained optimization.This document there are source code and test code as well as to the PDF file the detailed introduction of the method.Welcome to download.)

本程序是快速独立成分分析算法的主程序，包含了详细的注释，不含子程序。(This procedure is fast independent component analysis algorithm of the main program, including detailed notes, excluding subroutine.)
