分形课件，介绍了分形的理论的一些概念和用法(Fractal courseware, introduced the theory of fractal)

说明：  这是本人用Matlab实现音频噪声滤除的试验，要求分析并选用适当滤波器(using Matlab audio noise filtering tests, requirements analysis and the choice of appropriate filter)

压缩感知，对人脸进行跟踪的程序,今年欧洲图像会议的程序(Compressive Sensing，face track ,program )

在matlab环境下基于压缩感知对nc格式文件所进行的压缩感知处理(Perceptual processing in Matlab environment based on compressed sensing nc format file compression)

信道划分代码。它是做通信算法的基础。可以模拟简单的信道变化。(Channel code division. It is the basis for the algorithm to do communications. Can simulate a simple channel change.)

matlab心形~压缩包内有两个function函数，代入数据，很容易使用(matlab is very easy to use heart-shaped ~)

DSP理论分析以及MATLAB详细程序实例 非常不错(DSP theory analysis and MATLAB examples of detailed procedures)

说明：  实现了非均匀采样线性调频信号的精确重建，主要分为两部分：实现对线性调频信号的非均匀采样；非均匀采样重建。(A perfect reconstruction algrithm for non-uniform sampling LFM signals.)

this program helps you simulate the classification task whit MLP (multilayer preceptron) neural network

测试文本，选用著名的gettysburg这篇英文文本做为测试文本(Second, it fuses the features of the first singular value component and the second one, and then gets the complex feature vectors which reflect not only the statistic frequency but also the sequential structure of letters. In the end, the cosine similarity of texts is used to measure the similarity between the query and documents.)
