AdaBoost

说明：  用matlab绘制史密斯圆图，电子通信专业必备源码(Smith Chart in Matlab)

matlab最近点插值程序，通过这个程序可以实现影像配准前需要进行的匹配工作(matlab nearest point interpolation procedure, this procedure can be achieved by matching image registration work needs to be done before)

本电子书是针对初学者及中级学者对使用matlab的帮助 。(This book is for beginners and intermediate scholars use matlab help.)

chapter7 多种群遗传算法的函数优化算法(Chapter7 Function optimization algorithm based on multi population genetic algorithm)

carrier_count= 200 bits_per_symbol = 2 symbols_per_carrier = 50 loop=10 num=5 循环次数 10 子载波数 200 位数/ 符号 2 符号数/ 载波 50 训练符号数 5 循环前缀长度 T/4 调制方式 QAM 多径信道数 2（缺省） 信道最大时延 5 (单位数据符号) 仿真条件 收发之间严格同步 一个OFDM系统 在瑞利信道环境下 包括信道估计 比较适合初学者(carrier_count = 200 bits_per_symbol = 2 symbols_per_carrier = 50 loop = 10 num = 5 10 cycles 200 of the median number of subcarriers/symbol and the number of symbols of 2 /50 of the carrier the number of training symbol cyclic prefix length of 5 T/4 modulation QAM Number of multi-path channel 2 (default) 5 channel maximum delay (in the data symbol) strict synchronization between the simulation conditions receive an OFDM system in Rayleigh channel environment, including more suitable for channel estimation beginner)

PID极点配置控制（二阶系统，对象参数已知）(PID pole placement control (second-order system, object parameters are known))

说明：  用MATLAB编写的粒子群基本算法－PSO算法来求无约束函数的极值问题，得出比较好的结果(MATLAB prepared using the basic algorithm PSO-PSO algorithm to seek non-binding function of the extremal problem, arrive at some more good results)

这个函数也要被melcepst函数调用，用来进行计算Mel倒谱系数。这个函数的作用是构造mel滤波器组。(This function must be called melcepst function is used to calculate Mel cepstral coefficients. The role of this function is to construct mel filter bank.)

这是一个计算复杂网络参数closeness centrality 的程序，已调试(this program is used to caltulate closeness centrality)

基于matlab的窗函数滤波器设计 kaiser 窗(Filter design onmatlab)
