很有用的支持向量机的工具箱，工具箱里包含LS-SVM的核心算法以及DEMO,内附有工具箱的使用说明(well-known svm toolbox and user guide)

初学随机过程在MATLAB仿真上会有不懂，关于谱密度的几个例题(Some examples about spectral density are not clear in MATLAB simulation of initial stochastic process.)

说明：  1.此处主要探究的是嫦娥三号探测器在月球表面的软着陆问题。2.分析着陆轨道的特点，设计着陆轨道与各阶段的控制策略，对我国太空探测计划具有重要意义。3.此处主要采用微分动力学方程、最优控制策略等方法对问题进行分析和解决。(1. This paper mainly discusses the soft landing of chang'e-3 on the lunar surface. 2. It is of great significance to analyze the characteristics of the landing orbit, design the landing orbit and control strategy of each stage. 3. Differential dynamic equation and optimal control strategy are used to analyze and solve the problem.)

一款效果非常酷的纯js和CSS3分散式宝丽来图片画廊插件(A Very Cool Pure JS and CSS3 Decentralized Polaroid Gallery Plug-in)

说明：  设计一八木天线，振子数目为4，长度分别为：反射器长度0.39，主馈振子长度0.356，引向器长度均为0.3；反射器和主馈振子的距离0.265，主馈振子和第一引向器的距离0.2575，第一引向器和第二引向器的距离0.225。天线工作频率为400MHz，各振子分段数为9。 利用矩量法模拟该天线的电流分布，并绘制方向图。(A eight wood antenna is designed. The number of vibrators is 4 and the length is 0.39 for the reflector, 0.356 for the main feeder and 0.3 for the director. The distance between the reflector and the main feeder is 0.265, 0.2575 for the main feeder and the first director. The distance between the first director and the second director is 0.225. The working frequency of the antenna is 400MHz and the number of segments of each vibrator is 9.)

VB托盘图标的显示、隐藏，任务栏操作示例，可以隐藏任务栏，隐藏“开始菜单”、是否显示任务栏程序、是否显示托盘里的时间，是否不显示整个任务栏等，主要是对任务栏及其各个小功能的操作，若需要此方面编程技巧的，本源码相当有参考性。

PHP编码规范(第一版)(CHM)，这是程序员必备的编码规范了，非常实用。-PHP coding standard (first edition) (CHM), which is an essential feature of programmers coding standard, very practical.
