Differential Evolution optimized ELM with good introduction slides.

说明：  利用Matlab编写程序实现以下功能：以多项式形式输入系统前向通路传递函数和反馈回路传递函数，计算系统开环增益，判定型别，根据控制系统劳斯稳定判据原理，列出得到的任意阶次系统的劳斯表，判定闭环系统稳定性，若不稳定给出具有正实部极点的数目。 （1）根据用户输入的稳定度a，计算稳定的开环增益K的范围； （2）确定系统的最大稳定度a,计算相应的开环增益K的值。 (The use of Matlab programming to achieve the following functions: polynomial in the form of input system transfer function to the path and feedback loop transfer function, system open-loop gain calculation to determine type, according to Routh stability criterion control system theory, has been listed in the system of arbitrary order Routh table to determine the stability of the closed-loop system, if the stability of a positive real part gives the number of poles. (1) According to the stability of the user to enter a, calculation of the stability of the open-loop gain of the scope of K (2) to determine the most stable system a, the calculation of the open-loop gain of the corresponding K value.)

说明：  将pca和elman神经网络结合起来，找到了主要的变量(The PCA and the Elman neural network to combine to find the main variables)

说明：  这是一本超宽带通信书籍< 超宽带无线通信>>的原代码,ds_uwb,mb_ofdm,脉冲信号的形成(This is an ultra-wideband communications books lt; Lt; Ultra-wideband wireless communications gt; Gt; The original code, ds_uwb, mb_ofdm, pulse signal the formation etc.)

说明：  这是一个matlab和perl相互读取数据的程序，里面定义了数据读取的接口。(This is a mutual matlab and perl program to read data, which defines a data interface to read.)

无线传感器网络质心算法 matlab源程序代码(Wireless sensor network centroid algorithm matlab source code )

Solver for linear ecuations system (SOR-successive over relaxation), very usefull!!.

说明：  数据挖掘中的K均值聚类算法的MATLAB的实现(k means clustering algorithm)

Cluster generator。 By using this application it is possible to generate the well-known atomic clusters like Mackay-Icosahedron, Marks- and Ino-decahedrons and also fcc- and bcc-clusters.(Cluster generator。)
