Eigenvalues and eigenvectors of a symmetric matrix.

基本粒子群优化算法Matlab源程序 网上找到的别人做的很简单的程序，写的很精练很工整，据说优化效果不是很理想，由于没有时间去做很多测试，所以就先摆在这里，但愿以后能用得上。 下面是主函数的源程序，优化函数则以m文件的形式放在fitness.m里面，对不同的优化函数只要修改fitness.m就可以了通用性很强。 (Particle Swarm Optimization Algorithm Matlab source code online to find others to do the procedure is very simple, very concise writing is very neat, is said to optimize the effect is not very satisfactory, because there is no time to do a lot of testing, so I have to put in here, I hope that can use later. The following is the main function of the source, optimizing the function form of the document on Zeyi m fitness.m inside, as long as the different optimization functions can modify the fitness.m highly generic.)

　　利用matlab程序实现对一维信号进行连续小波变换，进而在程序的编辑过程理解一位连续小波变换的小波系数矩阵的含义。 　　同时通过对预算的到的小波系数矩阵进行分析解释，得到原始信号的频谱分布以及了解小波系数在尺度和位移两个分量上的意义。(Matlab program to achieve continuous wavelet transform of one-dimensional signal, and then in the editing process of the program to understand the meaning of a continuous wavelet transform coefficient matrix. Analysis to explain the budget to the wavelet coefficients matrix, the spectral distribution of the original signal, and understand the significance of the wavelet coefficients on the two components of scale and displacement.)

修改自wiley的书中的各种遗传算法（GA）matlab代码，还包括其他一些算法如粒子群优化，蚁群优化等，均已修改好用！(Modified since the book wiley various genetic algorithms (GA) matlab code, also includes a number of other algorithms such as PSO, ant colony optimization and so on, have been modified handy!)

给定一个数据集german.txt 通过libsvm来实现一定范围内参数C和sigma的最优值(需要先安装配置好matlab libsvm)
