CRC生成程序，可以自定义CRC位数等参数。十分具有参考价值(CRC generator, you can customize the CRC bits and other parameters. Is a reference value)

有效实行数据分类和图像分割的源码， 非常适合学习实用(image and data segmentation)

求函数最大值，可用于一元和二元函数，采用鱼群算法计算(Maximum demand function can be used for unary and binary functions, using fish algorithm)

iris normalization with convertion of cartesian to polar

说明：  利用小波分析的方法，来实现数字图像的分解(using wavelet for image)

聚类算法，不是分类算法。分类算法是给一个数据，然后判断这个数据属于已分好的类中的具体哪一类。聚类算法是给一大堆原始数据，然后通过算法将其中具有相似特征的数据聚为一类。这里的k-means聚类，是事先给出原始数据所含的类数，然后将含有相似特征的数据聚为一个类中。所有资料中还是Andrew Ng介绍的明白。首先给出原始数据{x1,x2,...,xn}，这些数据没有被标记的。初始化k个随机数据u1,u2,...,uk。这些xn和uk都是向量。根据下面两个公式迭代就能求出最终所有的u,这些u就是最终所有类的中心位置。(Clustering algorithm, not a classification algorithm. Classification algorithm is to give a figure, and then determine the data belonging to a specific class of good which category. Clustering algorithm is to give a lot of raw data, and then through the algorithm which has similar characteristics data together as a class. Here k-means clustering, is given in advance the number of classes contained in the raw data, then the data contain similar characteristics together as a class. All information presented in or Andrew Ng understand. Firstly, raw data {x1, x2, ..., xn}, the data is not labeled. K random initialization data u1, u2, ..., uk. These are the vectors xn and uk. According to the following two formulas can be obtained final iteration all u, u is the ultimate all these classes the center position.)

产生一个连续信号，包含低频，中频，高频分量，对其进行采样，进行频谱分析，分别设计三种高通，低通，带通滤波器对信号进行滤波处理，观察滤波后信号的频谱。(generating a continue time singal,which contains low,middle and high frequences,sampling it.analisize its spetrum.Then designing three kind filters are lowpass,highpass,bandpass filters and processing it.Observing its spetrum.)

基于matlab的人脸识别，不包含图像库，使用PCA分析方法(Matlab-based face recognition, image database does not include the use of PCA analysis)
