通过对语音的读入，对起进行语谱分析，以前，接着对语音进行了基音的提取，对语音进行分析！(Through the voice to read the language have been carried out spectral nalysis, in the past, followed by a pitch on the voice of the extraction, analysis of the audio!)

说明：  高等通信原理16_QAM symbol sequence of 2000 symbols and plot the constellation(Advanced Communication Theory 16_QAM symbol sequence of 2,000 symbols and plot the constellation)

learn Kalman smoother

说明：  调用函数可以使用拉格朗日插值公式、牛顿插值公式计算多项式，附有案例。(Call function can use Lagrange interpolation formula, Newton interpolation formula to calculate polynomials, with cases.)

一个指纹识别系统，用于提取指纹的特征。采用Matlab编译。包括若干测试图片。(A fingerprint identification system used to extract the fingerprint features. Compiled using Matlab. Including a number of test images.)

本程序基于Matlab，可以对特定波长光线在透镜系统中进行光线追迹。可以生成任意方向平行光，点光源任意角度光线，并对全反射，光线射出系统等特殊情况用红色标出。透镜数任意，透镜参数可设。(The program is based on Matlab, with a specific wavelength of light in the lens system for ray tracing. Parallel light can be generated in any direction, at any angle point source of light, and the reflection of light injection system and other special circumstances marked in red. Any number of lenses, lens parameters can be set.)

scalogram.m Function to calculate the phase and amplitude scalograms of a 1D signal. The analysis is done using quadrature pairs of log Gabor wavelets.

对一段语音进行端点检测并对检测的语音画出方框图，不同于一般只画竖线(Endpoint detection of a voice to draw the block diagram and detection of voice is different from the vertical line is generally drawn)

matlab编写的信号处理工具箱，很多程度，对于信号处理的很有用(matlab program for signal processing)
