用BP神经网络解决分类问题的MATLAB实现

说明：  matlab光线追迹例子，用于三片式光学结构追迹仿真(matlab for optic ray tracing)

利用Matlab编程实现主成分分析,从数学角度来看，这是一种降维处理技术(Using Matlab programming principal component analysis, from a mathematical point of view, this is a dimension reduction process technology)

鉴于本人去年7月份发布的《关于粗糙集和邻域粗糙集的基本理论和程序算例》其中有一些错误，可能给相关研究人员带来了误解，在此向大家道歉！ 同时在此资源中新增加了本人编写的邻域粗糙集的matlab计算程序，包括正域计算，约简计算，重要度计算，权重计算。 欢迎大家下载并交流学习！ 我所发布的两个版本的说明，以第二版本为主，第一个版本就不要下载了。 版权所有，除百度文库和中国程序员联合开发网上能下载到相关资源外，其他网站上的均为盗用。请尊重知识产权！(Given that I released last July, " the basic theory and procedures for rough sets and neighborhood rough set of examples," of which there are some errors, researchers may be brought to the relevant misunderstanding here to apologize! While a new addition to this resource I prepared matlab calculation procedures neighborhood rough set, including the positive domain calculation, reduction calculation, it is important calculation, the weight calculation. Welcome to download and share their knowledge! Two versions of the instructions I have released the second version of the main, the first version, do not download.

该软件利用Matlab的GUI功能,设计了一个人机交互界面,通过输入相应的参数来计算相应数据,在界面上即时显示相应的矩形和圆波导的场分布图,并可以根据需要进行电场和磁场的单独显示.(The software uses Matlab' s GUI functions, designed a human-machine interface, by entering the appropriate parameters to calculate the corresponding data, real-time display in the interface of the rectangular and circular waveguide the corresponding field distribution, and can be electric and magnetic fields as needed a separate display.)

基于MATLAB的小波变换，源码很有用,可以直接运行(using VC++ Wavelet image enhancement)
