一个模拟退火matlab程序，由m文件构成的工具箱，方便大家学习。(a simulated annealing procedures Matlab, m documents constitute the toolkit to facilitate learning.)

这是MATLAB课件，有很多matlab常用的命令及使用方法，适合想学matlab的人(This is the MATLAB software, there are a lot of matlab commonly used commands and how to use, suitable for people who want to learn matlab)

核极限学习机，引入核函数解决ELM求解问题，一旦参数选定，结果就稳定下来，不再混入随机。在原来版本上加入自己理解改写，使得代码更容易理解。(Kernel extreme learning machine, kernel function is applied to deal with ELM to solve the problem, once the parameters selected, the result is stabilized, not randomly in the original version on becoming a member of their understanding, makes the code easier to understand)

说明：  可以实现对Excel中数据的读取和聚类，并输出聚类结果(It can read and cluster data in Excel and output clustering results.)

由于利用fft变换存在频谱泄露和栅栏效应，本程序利用加窗fft算法，来解决这方面的问题(As the use of fft transform existing fence effect of spectrum leakage and the procedure used windowed fft algorithm to solve this problem)

说明：  关于雨点的散射程序，希望和有关同行探讨探讨(The scattering process on the rain, hope, and the study of peer)

用matlab解齐次线性方程，一般的二元三元或四元一次方程均不在话下，有了它，线性代数就不用愁啦(With matlab solution of homogeneous linear equations, the general binary three yuan or quaternary linear equation are mention, with it, do not worry friends of linear algebra)

认知无线电技术是当前缓解频谱资源紧张的有效解决方案，频谱感知是认知无线电的关键技术，其中，能量检测是经典的频谱感知算法，对于研究频谱感知的初学者来说比较重要。(Cognitive radio technology is an effective solution to alleviate the tension of spectrum resources. Spectrum sensing is the key technology of cognitive radio. Among them, energy detection is a classical spectrum sensing algorithm, which is important for the study of spectrum-aware beginners.)
