以Rossler方程!Duffing方程和Vanderpol方程为例,应用Matlab仿真工具进行模拟, 并对仿真结果作了简要说明和讨论,其中的示例对混沌研究和教学有一定的意义.(To Rossler equation! Duffing equation and the van der Pol equation as an example, the application of Matlab simulation tool for simulation, simulation results and a brief description and discussion, including examples of research and teaching on the chaos has a certain significance.)

noisegen.m：生成白噪声并按照指定信噪比对语音进行加噪； add_noisem.m：使用输入的噪音按照指定信噪比对语音进加噪； SNR_singlech.m：输入纯净语音和加噪后的语音，计算其信噪比； my_add_noise.m：调用上述函数进行加噪操作；(noisegen.m: white noise generated by the specified signal to noise ratio of the speech plus noise add_noisem.m: use the specified input noise into the signal to noise ratio of the speech plus noise SNR_singlech.m: pure voice input and processing after the noise voice, calculate the signal to noise ratio my_add_noise.m: call the above functions plus noise operation )

程序用于求解电力系统最优潮流，采用原-对偶内点算法，并辅以文献，有利于对内点法的学习。(Procedures for solving optimal power flow, the use of primal- dual interior point algorithm, supplemented by literature, internal point of law in favor of learning.)

Gradient calculation using first order derivative of Gaussian. by using a 2-D Gaussian kernel, derivatives along x and y directions are calculated

matlab的常用数据库表，另外还有一些个人搜集的数据库资料(matlab commonly used database tables, plus some personal information collected by the database)

Get reduce the size of an original sound file between half to three quarters of the initial size. The FLAC format is often used to sell music online, and as an alternative to MP3 to share when you want to reduce the file size would have

利用matlab开发的HSV空间分割的，手势识别程序，效果较好，背景复杂的情况下识别率也很高！！！(Recognition rate is also high in the case of using matlab development of gesture recognition program, the better the background is complex! ! !)
