说明：  遗传算法通过源代码 选择交叉编译 有较好的收敛性(Genetic selection through cross-compile the source code has a better convergence)

一个根据互功率谱求时延的例子,先加噪声，再延时得到两路信号(A according to each other for delay of the power spectrum example, first add noise, and then delay to get two signals)

小波包能量谱的计算，对信号进行频段分析，特征提取，用于模式识别(wavelet packet energy spectrum)

全方位入門學習matlab的書籍,從基本操作到資料分析與顯示都是做研究必備的基本工具.(a ebook for learning matlab, you can learn matlab basic operations and programming for your research.)

Scott Hudson, WSU Tri-Cities 1D electromagnetic finite-difference time-domain (FDTD) program. Assumes Ey and Hz field components propagating in the x direction. Fields, permittivity, permeability, and conductivity are functions of x. Try changing the value of "profile".(Scott Hudson, WSU Tri-Cities 1D electromagnetic finite-difference time-domain (FDTD) program. Assumes Ey and Hz field components propagating in the x direction.

对数据先进行经验模态分解得到不同特征尺度的信号分量，然后对所有的信号分量用AR模型进行预测得到预测后的分量，然后将预测后的分量进行重构得到最终的预测信号。(The data first empirical mode decomposition characteristics of the signal components of different scales, and then for all signal components obtained by AR model to predict the component forecasts, and then predict the components are reconstructed to obtain final predicted signal.)

利用：plot，stem，grid，line，axis，xlabel，ylabel，title 等绘制阶跃函数的图像。(draw the map of step function.)
