本程序是用MATLAB实现的小波零树图像压缩算法，请阅读附件中的README得到用法。注意，目前只是适用128×128的图像。(This procedure is used MATLAB realize the wavelet zerotree image compression algorithm, please read the README in the annex to be usage. Note that currently only applies to 128 × 128 images.)

对已知的数据进行勒让德多项式拟合，并求出计算点的函数值(Fitting the known data with Legendre polynomial and findding the function value at calculated point)

说明：  this is simple signal processing matlab code

人脸检测，使用的是matlab来做的，可以自由改动(facial detection)

说明：  本课题基于MATLAB平台的数字信号处理仿真演示系统。数字信号即离散信号，本设计带有一个丰富得GUI人机交互界面，一共包括4个部分，分别为：离散时间信号的卷积，基本函数的Z变换（单位阶跃信号，脉冲信号，斜变信号，正余弦信号，指数系列信号），Z变换的基本性质（线性，位移，z域尺度变换，时域卷积），傅里叶变换的基本性质。是一个不错的选题，GUI设计逻辑清晰，章节清晰，层次明了。(This project is based on MATLAB platform of digital signal processing simulation demonstration system. Digital signal is discrete signal. This design has a rich GUI human-computer interface, including four parts: convolution of discrete-time signal, Z-transform of basic function (unit step signal, pulse signal, oblique signal, sine cosine signal, exponential series signal), basic properties of Z-transform (linear, displacement, z-domain scale transformation, time-domain convolution), The basic properties of Fourier transform. GUI design logic is clear, chapter is clear, level is clear.)

本程序完成地震信号的提取检测。以往都是利用地震信号的能量比，此处创新选择地震信号的过零点作为边缘提取的判断。新方法效果不错。(The process is complete extraction of seismic signal detection. Past, the energy ratio of seismic signal, where innovation and choice as the seismic signal zero-crossing edge detection judgments. The new approach is very effective.)

自编的matlab验证各种计量经济学中正态性无偏性等一系列理论问题的程序(Directed the matlab verify various econometric CKS state of a series of theoretical issues without bias and other procedures)
