说明：  基于泰勒级数的灰度预测，这个里面的好多东西都写成了函数(Taylor series based on the gray prediction, the inside of a lot of things written in the function)

PCA matlab程序，可以通过改解释率，确定主元个数(PCA matlab code)

1.参数的设计 1）系统的变量比较多而且应用非常频繁，所以运用的变量要具有特征性 2）尽量使用课本上的变量，如果课本上的变量无法实现，在考虑其他自己定义变量 3）由于MATLAB使用变量可以不用先定义生命变量，所以可以直接使用变量 4）但是一些全局性的变量必须要定义( 1. Parameter design 1) system variables and the application is more frequent, so the use of the variable to have the characteristics of 2) the use of textbooks on the variables as possible, if the books can not be achieved on the variables, taking into account their other define the variable 3) use of the MATLAB variable life and variable can not be defined, so you can directly use the variable 4), but some global variables must be defined)

Analysis K-SVD: A Dictionary-Learning Algorithm for the Analysis Sparse Model.

基于MATLAB利用Particle-in-cell模型,对梯形管内壁等离子体离子注入过程,进行了二维数值模拟.计算结果表明在中心电极附近出现了“阳极鞘层”,该鞘层内部不存在离子,而且在鞘层边缘离子密度最高.在上下管壁上的离子注入剂量呈现“m”形分布.通过对注入过程中等离子体密度分布和不同时间段管壁不同位置离子注入剂量的跟踪,发现“阳极鞘层”扩展行为是导致“m”形分布的原因.由于梯形管形状的不对称性,“阳极鞘层”的边缘向梯形长底方向扩展较快.在注入初始时刻离子注入的能量很低,随着时间延长离子能量逐渐升高,这是由离子初始位置决定的.可见梯形管自身形状决定了鞘层形状和最终的离子注入能量和剂量分布.(Based on MATLAB use Particle-in-cell model, the trapezoidal pipe wall plasma ion implantation process, the numerical simulation of two-dimensional calculation results show that in the vicinity of the center electrode to a "anode sheath," which does not exist inside the plasma sheath, and the highest in the sheath edge ion density ion implantation dose showing the upper and lower walls of the "m"-shaped distribution through the process of injecting the plasma density distribution and the wall at different locations in different time periods ion implantation dose tracking, found that "anode sheath "extension behavior is leading to" m "-shaped distribution of the reasons due to the asymmetry of the trapezoidal shape of the tube," Edge anode sheath "extension to the end of a long trapezoid direction quickly in the initial moment of implantation energy ion implantation is low ion energy with time gradually increased, which is determined by the initial position of the ion. visible trapezoida)

OPtiFDTD reference OptiFDTD Technical Background and Tutorials Time Domain Photonics Simulation Software

根据 DVB-T 欧洲标准写的一个OFDM matlab 仿真，其中包括发射器和接收器。文章中有matlab程式的详细介绍，有仿真方框图，还有每步的实验结果分析，特别适合OFDM的初学者。算是OFDM比较简单的一个入门介绍。英文也比较浅显，可读性很强(According to the European DVB-T standard to write a OFDM matlab simulation, which comprises a transmitter and a receiver. Article has a matlab program in detail, there is a block diagram of the simulation, as well as analysis of the experimental results of each step, especially for OFDM for beginners. OFDM considered a relatively simple introduction to. English is also relatively simple, readable)
