说明：  本压缩包中还有13个程序，模拟了光在光纤中传输时的模式。希望能够给大家一点帮助(The compression package also 13 procedures, simulation of optical transmission in fiber mode. Want to give us some help)

主要阐述的是使用差分法解一类Bessel方程在不同边界条件下的离散解(elaborated in the main difference is the use of a solution like Bessel equation in different boundary conditions of the Discrete Solutions)

IIR filters are one of two primary types of digital filters used in Digital Signal Processing (DSP) applications (the other type being FIR). IIR means Infinite Impulse Response .

Fast search for Dirichlet process mixture models (This code implements the search algorithms (modulo a few minor changes) described in the Fast search for DPMMs paper at AI-Stats 2007. It should work out of the box with a reasonably recent version of matlab. Currently the code only contains the Dirichlet/Multinomial case, but the Gaussian case can be hacked in in about 5 minutes.)

遗传算法的详细仿真程序（matlab),算法详细介绍了遗传算法的功能和主要实现原理。难得的源码程序。(Genetic algorithms detailed simulation program (matlab), algorithm described in detail the function of genetic algorithm and the main achievement of the principle. Rare source procedures.)

函数作用： cwstd.m——用综合标准化法标准化矩阵 Cwfac.m——计算相关系数矩阵，计算特征向量和特征值，对主成分进行排序，计算各个特征值的贡献率，挑选主成分（贡献率达与85 ），输出主成分个数，计算主成分载荷 Cwscore.m——计算各主成分得分，综合得分并排序 Cwprint.m——读入数据文件，调用以上三个函数，并输出结果 原始数据：存储在src.txt中是一个30×8的矩阵 敲入命令： (PCA)

说明：  蒙特卡洛方法的MATLAB的m文件，看看有用没有(Monte Carlo method of MATLAB m-files to see if there is no useful)

optisystem联合matlab仿真基于m序列的一种调制格式，适合远距离传输，虽然调制效率较低，但传输距离很远(optisystem joint matlab simulation based on an m-sequence modulation format, suitable for long-distance transmission, although lower modulation efficiency, but the transmission distance is very far)

说明：  雷达信号脉冲多普勒的MATLAB源程序，可同时测得目标速度和距离信息(Doppler radar signal pulse of MATLAB source code, can be measured simultaneously target speed and distance information)
