深度优先搜索算法Matlab源码 ％ 此程序从国外网站收集得到，是标准的深度优先搜索算法，可实现节点遍历和检测回路的功能，详细情况请看原英文注释 ％ 我在此程序中添加了随机性，即遇到分叉时，随机选下一个节点，成为随机深度优先搜索算法(Depth-first search algorithm Matlab source this procedure site collected from abroad, is the standard depth-first search algorithm, can be achieved and the detection circuit node traversal functions, details see the original English Notes I added this procedure randomness, that is, bifurcation encountered when a randomly selected node, become a random depth-first search algorithm)

用于判断数据属于什么分布，有正态分布、泊松分布等(For the judgment under what distribution, normal distribution, Poisson distribution)

对利用录音设备对手机、电话等按键式密码输入终端进录音盗取银行卡密码的不法行为进行技术分析，利用MATLAB软件编程对按键式密码输入终端的按键音进行音频分析，基于短时能量和过零率对所采集的音频文件进行端点检测，提取出单个拨号音，然后对处理后的音频进行频谱分析、对比，从而识别按键式密码输入终端的按键音。(On the use of recording equipment on the phone, telephone touchtone input terminal password into the recording steal bank card passwords wrongful conduct technical analysis using MATLAB software programming for touch-tone touchtone password input terminal for audio analysis, based on short-term energy and zero-crossing rate of the acquired endpoint detection audio files, extract single dial tone, and then processed audio spectrum analysis, comparison, to identify key tone touchtone password input terminal.)

一种基于matlab/simulink的风力力发电建模系统，里面有非常多实用的模型能直接使用 (A wind power generation modeling system based on matlab/simulink, there are very practical model can be used directly)

说明：  本设计为基于MATLAB特征点匹配的指纹识别系统。带有一个GUI界面。主要对指纹图像进行三方面处理：图像预处理、特征提取和特征匹配。图像预处理包括四个步骤：图像分割、滤波增强、二值化、细化，对指纹图像进行预处理后，去除了原图像的冗余部分，方便后续的识别处理；特征提取主要是提取指纹图像细化后的端点和分叉点；特征匹配是利用两个指纹的图像进行特征点比较，来确定两幅图像是否来自于同一手指。(This design is a fingerprint recognition system based on MATLAB feature point matching. With a GUI interface. Fingerprint image is mainly processed in three aspects: image preprocessing, feature extraction and feature matching. Image preprocessing includes four steps: image segmentation, filter enhancement, binarization and thinning. After preprocessing the fingerprint image, the redundant part of the original image is removed to facilitate the subsequent identification processing; feature extraction is mainly to extract the refined endpoint and bifurcation point of fingerprint image; feature matching is to determine the two images by comparing the feature points of two fingerprint images Is it from the same finger.)

信道化接收发射机设计，很好用。供大家一起研究学习。(Channelized receiver transmitter design, easy to use. Research for everyone to learn.)

当我完成了我的运动检测里卖软饮料在matlab和更新代码,后来我改变了对C实现过程对DSP板。这是一份报告,对DSP板工作但是你可以发现这背后的概念。 (As I Initally performed my motion detection on matlab and updated the code, later I shifted the process on C to implement on DSP board. This is a report that works on DSP board but you can find the concept behind this.)
