说明：  包络谱的求取程序，已经过matlab运行，没有问题。(envelope,in matlab code)

说明：  核主成分分析方法是将主成分分析方法与核方法的有机融合，核心思想是通过引入核方法将输入空间的数据映射到特征空间，并在特征空间进行主成分分析，实现降维与提取非线性数据特征的双重目标。(The kernel principal component analysis (KPCA) is an organic fusion of principal component analysis (PCA) and kernel method. The core idea is to map the data from input space to feature space by introducing the kernel method, and carry out principal component analysis in feature space, so as to achieve the dual goals of dimensionality reduction and feature extraction of nonlinear data.)

着光纤光栅的技术的日益成熟，由于其具有插入损耗低,偏振相关性低,尺寸小以及成本低等优势(Fiber grating technology has become more sophisticated, because of its low insertion loss, low polarization dependent, small size and low cost advantage)

说明：  运用matlab求矢量x的均值和方差。代码实现简单，运行正确(Using matlab find the mean and variance of the vector x. Code is simple, right)

波形atom的提取，里边有应用实例，很不错(Waveform extraction atom inside application has several examples)

Monte Carlo方法的实质是通过大量随机试验，利用概率论解决问题的一种数值方法，基本思想是基于概率和体积间的相似性。它和Simulation有细微区别。单独的Simulation只是模拟一些随机的运动，其结果是不确定的；Monte Carlo在计算的中间过程中出现的数是随机的，但是它要解决的问题的结果却是确定的。(The essence of the Monte Carlo method is a numerical method to solve the problem through a large number of randomized trials, the use of probability theory, the basic idea is based on the similarity between the probability and volume. There are subtle differences between it and Simulation. Separate the Simulation simulation of random movement, the result is uncertain number of the Monte Carlo calculations in the middle of the process is random, but it is to solve the problem the result is determined.)

说明：  改进型的人工势场matlab代码，有注释(Oussama Khatib Real Time obstacle Avoidance for Manipulators and Mobile Robots. Proc of The 1994 IEEE.)

重采样，轮廓波变换，新型技术……Matlab轮廓波工具箱有用(backsample)

BP神经网络仿真 MATLAB仿真程序的程序文件(BP neural network simulation program MATLAB simulation program files)

一种蚁群算法的源程序 大家看看，如果需要联系我 还有其他的(an ant colony algorithm we look at the source code, if I need to contact the other)
