才用周期图法预测hurst指数。参数sequence为时间序列，isplot说明是否需要画图。(Have used the periodogram forecast hurst index. Parameter sequence for the time series, isplot explain the need for drawing.)

此程序为自适应信号处理中，求取LMS与GAL算法结合的性能的程序。(lms and gal algorythm)

三维有限差分算法，使用matlab编程，可以进行数值模拟(3-D FDTD code with PEC boundaries)

PCA based Feature Extraction and Matching

HHT工具箱，希尔伯特黄变换用的工具箱和emd程序代码(HHT toolbox, EMD decomposition of essential things, Hilbert-Huang Transform toolbox and program code used emd)

直方图是用面积表示各组频数的多少，矩形的高度表示每一组的频数或频率，宽度则表示各组的组距，因此其高度与宽度均有意义。 程序提取了很多直方图所需要的参数特征，如均值、方差、偏度、峰度、能量和熵。 (Histogram is that each group size the number of frequency, the height of the rectangular frequency of each group said that the number or frequency, the width of that group from each group, so the significance of height and width of both. Extraction procedures need a lot of parameters histogram features, such as mean, variance, skewness, kurtosis, energy and entropy.)

matlab源程序，可以仿真出来经典的BA无标度网络模型(Matlab source, can be simulated classic BA scale-free network model)

字符串动态显示，可以动态从左至右，也可重复显示，效果极佳(String dynamic display, you can dynamically from left to right, but also repeated showed excellent results)

高斯白噪声信道的仿真，自己写得，可以运行(Gauss　ｃｈａｎｎｅｌ)

FDTD Finite-Difference Time-domain in free space no ABC FDTD(t) runs FDTD for time t. FDTD implements the FDTD/staggered leapfrog scheme over time 0-max_time and space 0-max_space. This program simulates a gaussian pulse in the grid specified with max_time and max_space. The pulse is sent from the center of the problem space and disperses in both directions -Kira Heater
