说明：  模糊模拟、神经网络以及遗传算法的结合，matlab程序(The combination of fuzzy simulation, neural network and genetic algorithm, matlab program)

整数位运算及二进制显示。指定整数类型（byte，short,char,int)输入若干整数，选择位运算（&、|、^),显示位运算结果及整数二进制形式(The integer bitwise operations and binary display. Specified integer types (byte, short, char, int) Enter the number of integer bit arithmetic (& , |, ^), showing the result of the operation and integer binary form)

地震记录的数据，可以用来绘制地震记录，也可以作为地震反演的数据(Seismic wave inverse time migration program can realize the inversion of seismic wave)

说明：  Optics聚类算法 OPTICS没有显示地产生一个数据集合簇，它为自动和交互地聚类分析计算一个簇次序。这个次序代表了数据基于密度地聚类结构。它包含地信息，等同于从一个宽广地参数设置范围所获得的基于密度的聚类(Optics do not show clustering algorithm OPTICS to produce a collection of data clusters, it is automatically and interactively computing cluster analysis a cluster order. This order represents the data to cluster based on the density structure. It contains in information from a broadly equivalent range of parameters obtained by density-based clustering)
