QR

说明：  音频水印算法实现，其中包括水印的嵌入，音频水印常用攻击，以及检测算法的实现。(Audio watermarking algorithms, including the watermark embedding, audio watermarking common attacks, and the detection algorithm.)

Traveling Salesman Problem (TSP) Nearest Neighbor tour construction

Rife算法matlab仿真程序，并且给出了非常详细的说明注释。(Rife algorithm matlab simulation program, and gives a detailed description of annotation.)

Matlab/Simulink model of asynchronous machine

本文介绍的是一种改进的SPIHT算法，是基于图像编码的小波系数块的，它主要是把四个系数分成一个块，与阈值比较，分出重要与非重要，在进行编码。(This article is a modified SPIHT algorithm is based on the wavelet coefficients of image coding block, it is mainly divided into the four coefficients of a block, compared with the threshold value, separate the important and non important, during the encoding.)

数据测试，数据分析，数据还原，数据载入。(Data testing, data analysis, data reduction, data load.)

matlab处理图像代码，很不错，值得看看(matlab image processing code, very good, worth a look)

这是一个粒子群算法（pso）的MATLAB源程序(This is a particle swarm optimization (pso) the MATLAB source code)

说明：  可计算任意波形THD的小工具，非常方便；修改其输入波形即可得出结果(A tool for calculate THD)

说明：  通过调用IIR5函数对所给的信号进行滤波，其中通过fdatool 设计的直接1型切比雪夫滤波器的参数保存在coefficients1.mat文件中。(by calling IIR5 function as a signal to the filter, which it adopted fdatool design a direct-Chebyshev filter parameters stored in coefficients1.mat document.)
