求出多个信号的FFT频率并显示谱图，同时求出多个信号的功率谱并显示谱图(The FFT frequency of multiple signal and display the spectrum diagram, at the same time, the power spectrum of multiple signal and display spectrogram )

标准粒子群算法的实现思想基本按照粒子群算法(2) 标准的粒子群算法的讲述实现。主要分为3个函数。第一个函数为粒子群初始化函数 InitSwarm(SwarmSize......AdaptFunc)其主要作用是初始化粒子群的粒子，并设定粒子的速度、位置在一定的范围内。本函数所采用的数据结构如下所示： 表ParSwarm记录的是粒子的位置、速度与当前的适应度值，我们用W来表示位置，用V来代表速度，用F来代表当前的适应度值。在这里我们假设粒子个数为N，每个粒子的维数为D。(His thought of the implementation of the standard particle swarm algorithm according to the particle swarm algorithm (2)- the standard particle swarm algorithm about implementation. Mainly divided into three functions. The first function of particle swarm initialization function InitSwarm (SwarmSize... AdaptFunc), its main function is to initialize particle swarm particle, and set the particle s velocity, position in a certain range. The function of data structure is as follows: ParSwarm record table is the particle s position, speed and the current fitness value, we use W to represent the position, represented speed with a V, to represent the current fitness value with F. Here we assume that the number of particles N, each particle dimension for D.)

本程序是用于信号频谱分析的实验程序。 主要功能是进行信号的幅值谱计算；同时可完成在选定范围内谱峰的精确计算。( This procedure is used to test the program signal spectrum analysis. Main function is to calculate the signal amplitude spectrum the same can be done accurately calculate the spectral peaks within the selected range.)

计算近似熵、改进的样本熵及优化的模糊熵,均为matlab下编辑的程序，是很好的复杂度指标(approxy entropy, sample entropy and fuzzy entropy matlab code )

猴子摘桃海滩上有一堆桃子，五只猴子来分。第一只猴子把这堆桃子凭据分为五份，多了一个，这只 猴子把多的一个扔入海中，拿走了一份。第二只猴子把剩下的桃子又平均分成五份，又多了 一个，它同样把多的一个扔入海中，拿走了一份，第三、第四、第五只猴子都是这样做的， 问海滩上原来最少有多少个桃子？(Peach Monkeys on the beach there is a pile of peaches, five monkeys for points. The first monkey peach credentials this heap is divided into five copies, more than one, the monkey to more than one thrown into the sea, took a. The second monkey the rest of the peaches and what the average is divided into five, and there are one, and it is likewise more than one thrown into the sea, took a third, fourth, fifth monkeys are actually doing that , the question on the beach for at least the number of the original peach?)

对matlab初学者很有帮助，尤其是simulink的爱好者。(helpful to beginners Matlab, Simulink is particularly fond.)
