基于non-local means的maltab算法(nlm' s maltab algorithm)

这是Victor C.Chen"The Micro-Doppler Effect in Radar With DVD"的书还有它的Matlab的程序。(This is Victor C.Chen s book "The Micro-Doppler Effect in Radar With DVD" with Matlab codes.You have to put the codes on the Matlab folder that you can excute it.)

Log Spectral Distance Signal

画出BA模型，BA模型度分布，平均路径程度，集聚系数(Draw BA model, BA model distribution, average path degree, clustering coefficient)

matlab模拟退火智能优化算法，求取最短路径，已通过验证(matlab simulated annealing optimization algorithm intelligent, calculating the shortest path has been verified)

这是一个用matlab里面的simulink编写的一个wimax的链路，里面有很直观的链路图，可以对wimax有一个更为直观的理解。(This is a simulink with matlab written inside a wimax link, there are very intuitive link diagram, wimax can have a more intuitive understanding.)

Deterministic Maximum likelihood algorithm

基于混沌扰动算法来解决pso算法早熟问题，并用二者结合来训练灰色预测模型参数(Perturbation algorithm based on chaotic PSO algorithm to solve the early problems and to train with a combination of both gray prediction model parameters)

此程序是关于经济学中布莱克斯科尔斯模型 的matlab实现(This procedure creates a three-dimensional plot showing how gamma changes relative to price for a Black-Scholes option. Recall that gamma is the second derivative of the option price relative to the underlying security price. The plot shows a three-dimensional surface whose z-value is the gamma of an option as price (x-axis) and time (y-axis) vary. It adds yet a fourth dimension by showing option delta (the first derivative of option price to security price) as the color of the surface)

1 录入一段语音，对其进行时域频域处理，通过变频、变速达到变声目的，且使处理后的语音信号不影响正常收听与理解。 2 用图形用户界面（GUI）对上述变声前变声后进行时域频域图形输出，不同的频率、速度有不同的输出，且对前后波形进行比较 (1 entry a voice, the frequency domain and time domain by frequency conversion variable speed, processing to make the treatment and voice purpose, after the speech signal shall not affect the normal to listen to and understand. 2 with the graphical user interface (GUI) voice of the above voice before after the frequency domain in the time domain graphics output, different frequency, speed have different output, and compared before and after waveform )
