Tutorial of filter: design a lowpass FIR filter of cutoff requency 0.3*pi. Plot the impulse responses h(n) and magnitude responses of the designed filters

说明：  1、主要是产生0，1，2，3，阶贝赛尔函数图形。 2、产生线性调频信号和它的的频谱图。 3、产生单个脉冲的三维模糊图以及对应的等值图。 4、它是程序3的嵌套子程序，用于产生单个脉冲。 5、用于产生高斯和瑞利分布函数。 (These programs can produce 1、Bessel graph；2、LFM signal and its amplitude spectrum；3、ambiguous graph 4、Gaussian and Rayleigh function. )

说明：  MATLAB的完全教程，详细介绍了MATLAB的功能，给使用者参考。(MATLAB complete tutorial, detailing the MATLAB functions to users.)

　K-means算法是最为经典的基于划分的聚类方法，是十大经典数据挖掘算法之一。K-means算法的基本思想是：以空间中k个点为中心进行聚类，对最靠近他们的对象归类。通过迭代的方法，逐次更新各聚类中心的值，直至得到最好的聚类结果。(K-means algorithm is based on the division of the classic clustering method, is ten classic one of data mining algorithm. K-means the basic idea of the algorithm is: to the space K point as the center of the cluster analysis, near their object classification. Through the iterative method, each successive update clustering center value, until get the best clustering results. )

这是一个matlab代码包，里面包括一百多个数学问题的求解方法，非常实用(this package of matlab code contains more than 100 mathematical problem s solutions)

参考外国文献，通过MATLAB程序编写了以两个简单的blcOzp映射构造一个双混沌互扰 ZaUxxYq系统,提出了采用先进的两混沌调制模型的无线加密算法，具有防窃听的能力，调试无错误。(References to foreign literature, through MATLAB programming the blcOzp with two simple mapping to construct a mutual interference ZaUxxYq dual chaotic systems is proposed based on the wireless encryption algorithm dual chaotic mutual interference system has the ability of anti-wiretapping, debugging errors. )
