这是关于用MATLAB实现遗传算法程序的原理介绍，包括也选择、交叉、变异等算子的程序。(This is about using MATLAB genetic algorithm program to achieve the principle of description, including also selection, crossover and mutation operators of the program.)

This is also related to shift keying mod technique.....it is also very helpfull for the biggner who want to do digital mod techniques.........

二极管箝位五电平电路建模与仿真的mdl文件，本人所作作业，绝对可以运行。(Diode-clamped five-level circuit modeling and simulation mdl file, I made the job can definitely run.)

二分类逻辑回归matlab代码,运行有效，包含图形说明。(Binary logistic regression matlab code to run efficiently, including graphical instructions.)

local mean decomposition 软件原理描述(local mean decomposition Software Principles)

基于矩量法仿真的笼形天线宽带化设计 (Method of Moments simulation cage antenna design is based on broadband)

dijkstra算法和例程，里面有相关的中文说明，容易学习！(dijkstra algorithms and routines, which have the relevant Chinese instructions, easy to learn!)

因为傅立叶变换对应的是无限信号,信号经过分帧后变成有限信号,分帧的信号再进行傅立叶变换后,高频部分将有 泄露 ,所以要加窗. 窗函数的拼谱都是在某高频部分截止,所以每帧信号加窗后的傅立叶变化,频谱基本 泄露 (Because Fourier transform corresponding is infinite signals, signals after framing become limited, framing signal again after Fourier transform, the high frequency part will have leaked , so to add window. Window function spell spectrum are in a high frequency part of the globe, so each frame and window after Fourier transform, signal spectrum basic leak )

本段程序实在MATLAB环境下对输入的语音序列x进行MFCC参数的提取，返回MFCC参数和一阶差分MFCC参数。(Voice input sequence x extracted MFCC parameters, return parameters and the first-order difference MFCC MFCC parameters)
