完美的ID3决策树分类算法源程序

基于SURF特征点的图像配准代码，可实现两幅图的特征提取及匹配(SURF feature points based on image registration code)

利用声卡采集声音，实现声音的滤波处理。很实用，实用matlabGUI写的。最好用matlab2008a以上的版本打开。(this is a sound filter GUI written by MATLAB.)

21世纪高等院校创新教材，对数值计算的多种方法进行说明，并有实验说明，是现在研究生教育使用教材。(Innovation teaching material in colleges and universities in the 21st century, a variety of methods of numerical calculation, and experiments shows that graduate education is now using the teaching materials. )

说明：  改进的差分粒子群算法，并用于求函数极值，程序中分别于DE PSO 蛙跳进行对比，结果显示，改进的差分粒子群更好(The improved Differential Particle Swarm Optimization (DPSO) algorithm is used to find the function extremum. The program is compared with DE PSO frog jump, and the results show that the improved DPSO is better.)

基本粒子群是计算智能领域，除了蚁群算法、鱼群算法之外的一种群体智能优化算法，PSO算法源于对鸟类捕食行为的研究，鸟类捕食时，找到事物最简单有效的策略就是搜寻当前距离食物最近的鸟的周围区域。
