自己用matlab编写的求FFT的程序，程序简单易懂！(Seeking FFT program written using matlab, the program is simple and easy to understand!)

根据一组样本数据的均值和协方差矩阵随机产生正态分布以及对数正态分布的任意规模的样本数据。(According to a set of sample data mean and covariance matrix randomly generated normal and lognormal distribution of the sample data of any size.)

几个简单的遗传算法例子，一般有点相关基础的都能看懂，很容易的。(Few simple examples of the genetic algorithm, based on the general correlation can understand a little bit, very easy.)

用有限时域差分方法编写的光子晶体一个程序，计算了透射系数。( applies finite difference time domain method to analyze the band gap of Two-Dimensional cirque Photonic Crystal. )

采用四种埪制律进行单神经元PID控制，即无监督的Hebb学习规则；有监督的Delta学习规则；有监督的Hebb学习规则；改进的Hebb学习规则。(Kong legal system of four single-neuron PID control, the Hebb learning rule is unsupervised a supervised learning rule Delta a supervised Hebb learning rule modified Hebb learning rule.)

说明：  利用改进的粒子群算法实现了分布式电源的优化配置！有详细的中文注释！(The improved particle swarm optimization algorithm is used to optimize the configuration of distributed power supply. Detailed Chinese notes!)

说明：  值得深刻阅读的基于CP的OFDM同步程序 这是一个非常好的用于OFDM的基于CP的 最大似然符号定时同步和载波同步的MATLAB仿真程序，经本人深入阅读吸收经典文献，反复编程调试而提炼而成，代码精炼有序，绝对没有错误，由此程序仿真得到的同步曲线与经典文献完全一致。同仁们阅读此程序一定受益匪浅！ 这里不吝成果，特上载与诸位网友共享。也欢迎同仁们提供更多的优秀程序。 由于文献要求采用N＝1024个子载波的OFDM，运行此程序需2分钟－3分钟的时间。 (Worthy of profound reading of the CP-based OFDM synchronization process this is a very good CP for OFDM-based maximum likelihood symbol timing synchronization and carrier synchronization of the MATLAB simulation program, after I read the absorption of classical literature in depth, repeated programming and debugging extracted from the symbol of refined and orderly, there is no error, this procedure has been synchronized simulation curve is fully consistent with classical literature. Tongren have read this procedure will definitely benefit! Spared the outcome here, especially to upload to share with you friends. Tongren also welcome to provide more excellent program. Documentation required as a result of N = 1024 sub-carrier OFDM, to run this process will take 2 minutes-3 minutes.)

Kriging插值工具箱，可做可历尽内插(Kriging interpolation toolbox, can be experienced all kinds of interpolation)

说明：  混沌时序多步预测函数的MATLAB程序,对于研究混沌时间序列的朋友来说是个好程序(Chaos forecast sequential multi-step procedures MATLAB functions for research chaotic time series of friends is a good procedure)
