一个用于对汽车销售公司进行财务数据回归分析的实例(A car sales company financial data regression analysis instance)

分数阶系统的计算工具，解决一般解及动力学行为的问题(tools for solving fractional-order systems)

说明：  取u=0.0375，阶数L=11，比较w取不同值时LMS算法的运算结果之间所存在的差异(observing the diferent result of LMS when "w" is diferent (u=0.0375 and L=11))

In this presentation the method of least squares will be used to derive a recursive algorithm for automatically adjusting the coefficients of a tapped-delay-line filter, without invoking assumptions on the statistics of the input signals. This procedure, called the recursive least-squares (RLS) algorithm.

this matlab code reads the data text files UCI Spoken Arabic Digits and save the results in a mat file which user can easily use.

用七元线形天线阵（ULA） 已知：信号中心波长为2,天线阵元的间距为1米,快拍数为2000，空中有四个 源信号,假设它们的频率：0.015, 0.05, 0.02, 0.035 四个源信号的方向分别为：pi/4 pi/3 pi/6 3pi/4 求： 1）在不加入噪声的情况下,画出传统波束形成法、Bartlett波束 形成法、Capon波束形成法的空间谱图； 2）在加入高斯白噪声的情况下,假设信噪比为10dB，画出传统波束 形成法、Bartlett波束形成法、Capon波束形成法的空间谱图。(7-element linear antenna array (ULA) Known: the signal center wavelength is 2, the antenna element spacing of 1 m, the number of snapshots for 2000, the air there are four Source signal, assuming that their frequency: 0.015, 0.05, 0.02, 0.035 The direction of the four source signals: pi/4 pi/3 pi/6 3pi/4 Requirements: 1) not to join the noise, to draw the traditional beam-forming method, Bartlett, beam Formation method, Capon beamforming method of the space spectrum 2) by adding Gaussian white noise, assuming that the SNR is 10dB, to draw the traditional beam Formation method, Bartlett, beamforming, Capon beamforming method of the space spectrum.)

MATLAB6.5接口编程(本人加了目录).(MATLAB6.5 Programming Interface (I added a directory).)

一个eemd的程序，对于初学者非常的适用，程序只需要输入实验数据就可以调试出来，可以下下来看看(A eemd program for beginners, very applicable, can debug program only need to input experimental data, can be down and have a look)
