说明：  matlab的简单练习，对图像进行基本操作。课堂练习而已(matlab simple exercises, perform basic operations on the image. Workshop only)

说明：  CCNA中文笔记第2章 　DoD模型被认为是OSI参考模型的浓缩品,分为4层,从上到下是1.DoD模型的Process/Application层对应OSI参考模型的最高3层 　　2.DoD模型的Host-to-Host层对应OSI参考模型的Transport层 　　3.DoD模型的Internet层对应OSI参考模型的Network层 　　4.DoD模型的Network Access层对应OSI参考模型的最底2层 (CCNA Chinese Notes Chapter 2 DoD model OSI reference model is considered concentrated products, divided into four layers, from top to bottom is 1.DoD Model Process/Application layer of OSI reference model corresponds to the maximum 3-layer model 2.DoD Host-to-Host layer corresponds to OSI reference model Transport Layer 3.DoD model Internet layer corresponds to OSI reference model Network model Network Access Layer 4.DoD OSI reference model layer corresponds to the bottom layer 2)

利用matlab产生dll的方法、步骤。可以利用matlab来生成dll(Step method, produced by DLL matlab. You can use matlab to generate DLl)

计算常用指标Gmean,F-score,sensitivity,specificity,precision,roc和auc曲线，输入test_label,predict_label两个列向量，即可获得以上指标(calculate some indexes)

根据地理坐标求两点之间的距离,应用在物流、交通运输领域(Geographical coordinates for the basis of the distance between two points, used in logistics, transportation)

里面是关于matlab最基本的学习资料，有两个版本的，大家可以根据自己不同的要求，去学习它。(Matlab inside on the most basic learning materials, there are two versions, we can according to their different requirements, to study it.)

关于高精度加法运算的无误差变换matlab算法程序。(Accurate floating point sum programs)

基于内容的图像检索程序 实现图像的检索 图像处理 图像特征提取 图像检索 (Content-based image retrieval to extract image retrieval program for image retrieval of image processing image features)

小波包法去除放电信号中的白噪声，采用db4小波分解4层(Removal of wavelet packet discharge signal white noise, using four-layer wavelet decomposition db4)

很多的都想用自已的和序控制自己的电脑,这里有一些常用函数,希望对大家有用(Many want to use their own and the sequence to control their own computer, here are some commonly used functions, in the hope that useful to everybody)
