毕设使用的粒子群算法求函数最小值测试源程序

一个是用matlab实现指纹识别程序。里面附带指纹图片，并用其作为例子实现指纹图像的匹配。(One is to use matlab to achieve fingerprint identification procedure. Which comes with the fingerprint image, and use it as an example to achieve the matching fingerprint images.)

MATLAB基本函数集，对学习MATLAB指令有很大的帮助！！！(Basic set of MATLAB functions, MATLAB commands to learn a great help! ! !)

这是个MATLAB 得程序，有关的内容是 无线传感器网络得会直接点和拓扑图问题，一共有2个算法，希望对对无线传感器网络感兴趣的得大大们有一定的帮助。谢谢大家。 (it is the problem of wsn topology control, if you are interested in it please download it . )

MSChart操作实例，可以轻松编码实现饼图，折线图，柱状图(MSChart operation example, you can easily Coding pie charts, line charts, bar charts)

心理声学模型，频谱绘制，把人听到的声音模型展示出来，它解释人各种听感的生理原理。有需要的可以下载参考(Psychoacoustic model, spectral rendering, there is a need to download the reference)

说明：  基于MATLAB设计的声纹识别系统，目前是主要的研究方向，拥有广阔的前景，具有很高的研究价值(The voiceprint recognition system designed based on MATLAB is the main research direction at present, and has a broad prospect and high research value)

基于DWT-SVD的数字水印算法，经过调试，可以运行，附有图片
