说明：  matlab常用算法之一，MATLAB初学者可好好利用(One commonly used algorithm matlab, MATLAB beginner can make good use of)

用matlab对M=8的PSK系统进行蒙特卡罗仿真，分析其误码率(Using matlab for M = 8 the PSK system Monte Carlo simulation, to analyze the bit error rate)

Chebfun找到一个类似的问题已经解决了别人使用作为一个模板。这一页将你们连接到几十个这样的模板,称为Chebfun例子。每一个例子是一个M-file生产文本和/或图形输出,执行,在大多数情况下,在少于5秒。你也可以执行的例子,用Matlab命令的出版得到一个包含更多的信息的故事。一类开路(出版(“文件名”))去看在你的屏幕上最快的版本或出版(“文件名”)为一个更好的格式化乳胶版本,它将出现在一个目录叫做html。公布的产量也可直接下载作为一个pdf档案。(The quickest way to solve your problem with Chebfun may be to find a similar problem someone else has solved to use as a template. This page connects you to dozens of such templates, called Chebfun Examples. Each example is an M-file producing text and/or graphical output which executes, in most cases, in less than 5 seconds. You can also execute the example with Matlab s PUBLISH command to get a more informative story. Type open(publish( filename )) to see the quickest version on your screen or publish( filename , latex ) for a better formatted LaTeX version, which will appear in a directory called html. The published output is also available for direct download as a pdf file.)

运用分步傅里叶法求解NLS方程，最终输出时序图和频域图(Using split-step Fourier method for solving NLS equation, the final output timing diagrams and frequency domain)

matlab通带滤波，是在频域内实现的，最好用于地震波，或其他一些信号逐渐衰减的情况(bandpass filter,used for strong motion data process for better. because the software carry out the filter function through fft)

零相移滤波器m函数，优点是克服了滤波器产生的相位滞后，缺点是本仿真不能保证实时性，其原理为输入一次序列，正反各变换一遍。(Zero phase shift filter m function, the advantages of the filter to overcome the phase lag, the disadvantage is that the simulation can not guarantee real-time, the principle of the input sequence, the pros and cons of each conversion.)

说明：  xfoil项目机翼demo的matlab代码，可以进行测试(Xfoil project wing demo matlab code, can be tested)

一个数据预处理过程中消除多项式趋势项的程序(this is a program about eliminating polynomial trend)

Kernel principal component analysis (kernel PCA) [1] is an extension of principal component analysis (PCA) using techniques of kernel methods. Using a kernel, the originally linear operations of PCA are done in a reproducing kernel Hilbert space with a non-linear mapping.
