matlab的常用命令，对于matlab的初学者非常有用。都是关于matlab的最基本的函数命令。(matlab commonly used commands, very useful for matlab beginners. Are the most basic functions on matlab command.)

用MATALB做的曲柄滑块机构的动画（包括加速度、速度和位移的变化分析）代码(Do with MATALB animation slider-crank mechanism (including acceleration, velocity and displacement change analysis) code)

pendulum model, its non linear control

无迹卡尔曼滤波程序，主要子程序包括：轨迹发生器、系统方程、测量方程、UKF滤波器(UKF Filter)

对语音信号加入窄带噪声并用小波去除噪声并显示结果(add narrowband noise to signal and decrease it with wavelet)

this matlab code is of interpolation of some given points using newton s divided difference method.

单相矩阵变换器的经典模型，由整流级和虚拟逆变级组成(The classic model of the single-phase matrix converter, composed by the rectifier stage and virtual inverter stage)

读取语音信号（用matlab的wavread指令），把语音信号分帧、加窗，进行清浊分割，提取基 频，这一部分较简单，自己编程序做。参考文献自己到图书馆期刊网上查找。 提取语音信号的lpc参数，可调用lpcfit.m 程序（我提供，见附件），将源、目标语音的浊音 段的lpc系数进行DTW规整，调用pathita2.m 程序（我提供，见附件）。将规整得到的lpc系数 转换成lsp参数，调用lpcar2ls.m 程序（我提供，见附件）， 再进行转换映射，调用matlab 的指令newrbe。(read the speech signal (using Matlab wavread Directive), Voice Signal frames, Windowed, Qingzhuo segmentation, extracting fundamental frequency, this part is relatively simple, they programmed to do. References their online journals to the library search. Voice Signal Extraction lpc parameters can be called lpcfit.m (I provide, see Annex), the source, Voiced objective voice of the lpc coefficient DTW structured, Call pathita2.m (I provide, see Annex). Structured to the lpc lsp conversion coefficient parameters, calling lpcar2ls.m (I offer see Annex), the shift mapping, called the directive newrbe Matlab.)

一维小波降噪，该程序运用多尺度小波变换法进行降噪，效果不错(One-dimensional wavelet noise reduction, the program is the use of multi-scale wavelet transform for noise reduction and good results)
