主要讲了一些matlab的一些实用方法和技巧，方便对matlab的入门学习及掌握(Mainly about some matlab some practical methods and techniques to facilitate the entry of matlab learn and master)

1998年, Watts和Strogatz 提出了小世界网络这一概念,并建立了WS模型。 实证结果表明,大多数的真实网络都具有小世界特性(较小的最短路径) 和聚类特性(较大的聚类系数) 。 WS小世界模型构造算法 1、从规则图开始：考虑一个含有N个点的最近邻耦合网络，它们围成一个环，其中每个节点都与它左右相邻的各K/2节点相连，K是偶数。 2、随机化重连：以概率p随机地从新连接网络中的每个边，即将边的一个端点保持不变，而另一个端点取为网络中随机选择的一个节点。其中规定，任意两个不同的节点之间至多只能有一条边，并且每一个节点都不能有边与自身相连。 (In 1998, Watts and Strogatz proposed the concept of the small world network, and the establishment of the WS model. The empirical results show that most real networks have small world (the smaller the shortest path) and clustering properties (high clustering coefficient). WS small-world model construction algorithm 1, from the rules FIG: consider a nearest neighbor coupling network with N points, they are surrounded by a ring, wherein each node and its left and right adjacent to each of K/2 connected to the node, K is an even number. The 2 randomized reconnection: randomly with probability p from the new connection on each side of the network, coming section of one of the endpoints remain unchanged, while the other endpoint is taken as the random selection of a node in the network. Which states that between any two different nodes can have at most one edge, and each node can not be connected to its own side.)

说明：  在MATLAB环境中，利用简单的加法和乘法实现基2时间抽取的FFT变换，并且能够计算出峰值点的最大值,数据点数为2的整数次幂。学习程序有利于对FFT变换的理解，以及在单片机环境或者是DSP环境中编写FFT变换C语言程序。(In the MATLAB environment, using simple addition and multiplication of time taken to achieve the base 2 FFT transform, and can calculate the maximum peak point. Learning process is conducive to the understanding of the FFT transform, and the DSP in the microcontroller environment, the environment or the preparation of FFT, C language program.)
