小波包分析提取振动信号中的特征频率，重要参数的提取，用于时频分析算法。( Wavelet packet analysis to extract vibration signal characteristic frequency, Extract important parameters, For time-frequency analysis algorithm.)

算术编码，matlab实现编码与译码，而且不考虑其精度(Arithmetic coding, matlab coding and decoding achieve, and do not take into account their accuracy)

HBM实行快速傅里叶变换，这是谐波平衡法中的一个重要的环节(Harmonic Balance Method is a very useful method in solving rotor dynamics, and fast fourier transform is an important part in it)

MATLAB的一些基本命令和常用函数，非常适合初学者(MATLAB commands and some basic common functions, ideal for beginners)

说明：  在耳语转化为正常音的过程中需要到的一些简单实用语音处理的程序(Whisper into the normal sound in the process to go to some of the simple and practical procedure for speech processing)

可以实现空间后方交汇,相对定位,光束法空间后方交汇(Space behind the convergence can be achieved relative positioning behind the convergence of the bundle space)

功率谱估计及其MATLAB仿真.经典功率谱估计是将数据工作区外的未知数据假设为零,相当于数据加窗。经典功率谱估计方法分为:相关函数法(BT法)、周期图法以及两种改进的周期图估计法即平均周期图法和平滑平均周期图法,其中周期图法应用较多,具有代表性。(The power spectrum estimation and simulation of MATLAB. Classic power spectrum estimation is unknown data in the data outside the workspace is assumed to be zero, equivalent to the data window. Classic power spectrum estimation method is divided into: the correlation function method (BT Act), the periodogram and two improved cycle diagram estimation method the average periodogram and smoothed average periodogram, which the periodogram method used more often, on behalf of sex.)
