数字信号处理LMS算法，处理输入信号与参考信号的误差，显示收敛曲线(LMS algorithm for digital signal processing, processing the input signal and reference signal of the error, shows the convergence curve)

说明：  一个关于主成分分析的matlab演示，十分有用(A principal component analysis on matlab demo, very useful)

利用Matlab软件编写的轨道不平顺数据分析程序能够对轨检车测得的不平顺数据进行处理,得到功率谱密度分布函数.轨道不平顺分析程序包括轨道不平顺数据预处理、轨道不平顺谱分布函数计算以及根据实测的车体振动加速度,对轨道不平顺与车体振动加速度进行相干分析、提出对行车运行有不利影响的不平顺波长范围等.研究结果表明:车辆的动力特性与轨道不平顺有密切关系.高低不平顺对车体垂向振动影响显著,轨向不平顺对车体水平振动影响显著,水平不平顺对列车垂向、横向振动均有显著影响.(Matlab software written track irregularity data analysis program able to track inspection car irregularity measured data are processed to obtain the power spectral density function. Track Irregularities track irregularity analysis procedures including data preprocessing, track irregularity spectrum distribution function calculations, and based on the measured vibration acceleration of the vehicle, with the body of track irregularity acceleration coherent analysis, have an adverse impact on traffic running irregularity wavelength range, etc. the results show that: the dynamic characteristics of the vehicle and the track irregularity closely related. rough along the vertical vibration of the vehicle significantly, rail irregularity vibration to levels significantly affect the body, the level of irregularity to train the vertical and horizontal vibration significantly affected.)

相位累加器，即DDS频率合成器的MATALB实现，采用M文件编写的S函数(Phase accumulator, that is, the DDS frequency synthesizer MATALB realized, the use of M' s S function documentation)

SVPWM 矢量控制系统仿真源码 没太看明白 大家试着看看吧(SVPWM vector control system based source did not quite understand this we try to look at it)

ROLE OF POWER ELECTRONICS IN RENEWABLE ENERGY SYSTEMS

matlab环境下开放的心理声学模型，基于Matlab标准，包括FFT分析，掩蔽阈值分析等(psychoacoustic model open in the Matlab environment, Matlab-based standards, including FFT analysis, masking threshold analysis)

说明：  面阵中二维角度DOA估计算法，采用ESPRIT，经典算法，注释清晰，可拿来直接用(Two dimensional angle DOA estimation algorithm in array, using ESPRIT, classic algorithm, clear notes, can be used directly)

matlab7.0这本书的源代码，应该对学习这本数的朋友们有很大的帮助(matlab7.0 this book)

Here s is a code for alamouti scheme having transmitter diversity! :) njoooy!
