512点FFT程序，分10级蝶形运算完成。(512-point FFT program, sub-10 butterfly to complete.)

This is a simple function which caculates the spherical harmonic.The archive includes four M files ,and the file Comx_Sph.m is the main function.Given the degree l ,the index m and the variable x ,you can get the value of spherical harmonic.For more details ,you may read the programs.

用于车道线检测的代码，其中用到了hough变换，能有效实现车道线的检测(For lane detection code, very practical, using hough translate,achieve lane detection)

hilbert变换的程序，输入一个时间序列，既可以得到希尔伯特变换之后的复信号，输出结果是复信号(hilbert transformation)

我在网上找了一份Lee滤波的程序，但实际使用发现是均值滤波，我自己重新写了一份，应该可以使用。(I find the Internet a Lee filter process, but the actual use is found to mean filtering, I re-wrote a, should be used.)

说明：  粒子群算法，很有用的一个设计程序，如果需要优化，可以使用(Particle Swarm Optimization )

BACK PROPOGATION ALGORITHM FOR MATLAB

说明：  关于迭代学习算法的简单例程，其中迭代次数可自行更改，次数越高跟随效果越好(example of ILC you can exchange the parameter i_nby yourself it will perform better when the praameter get larger value)
