混沌映射(序列)matlab算法“小全”：Logistic、Henon、帐篷、kent(含混沌二值图像生成函数)的matlab程序(Chaotic map (sequence) matlab algorithm " Souvenir" : Logistic, Henon, Tent, kent (including chaotic binary image generating function) matlab program)

用matlab的各种编程例子，可以供大家更好的理解掌握MATLAB，自己觉得挺有用的。(Various matlab programming examples for all to better understand and grasp the MATLAB feel quite useless.)

This program is able to obtain the maximun value of a given matrix NxM. The output arguments are the maximun value,the row ande the column in wich this value locates.The input value is a matrix os NxM.

给定一组数据，利用特征值方法简单的计算其主成分，简单易懂，适合初学者学习(simple matlab code of PCA)

该文件使用FIR滤波器滤除采集的心电信号中的工频干扰，实测滤波效果不错，不过并不能处理基线漂移。文件中提供了滤波器的定点系数。(The file uses the FIR filter to remove the collected ECG frequency interference, measured the filtering effect is good, but does not deal with the baseline drift. Document provides a fixed filter coefficients.)

粒子群算法，也称粒子群优化算法（Particle Swarm Optimization），缩写为 PSO， 是近年来发展起来的一种新的进化算法(（Evolu2tionary Algorithm - EA）。PSO 算法属于进化算法的一种，和遗传算法相似，它也是从随机解出发，通过迭代寻找最优解，它也是通过适应度来评价解的品质，但它比遗传算法规则更为简单，它没有遗传算法的“交叉”(Crossover) 和“变异”(Mutation) 操作，它通过追随当前搜索到的最优值来寻找全局最优。这种算法以其实现容易、精度高、收敛快等优点引起了学术界的重视，并且在解决实际问题中展示了其优越性。(Particle swarm optimization, also known as particle swarm optimization (Particle Swarm Optimization), abbreviated as PSO, is a new evolutionary algorithm developed in recent years ((Evolu2tionary Algorithm- EA) .PSO algorithm is an evolutionary algorithm, and similar genetic algorithm, it is also starting random solutions, through iterative search for the optimal solution, which is also uated by the quality of the fitness solution, but it is much simpler than genetic algorithms rule, it does not have the genetic algorithm cross (Crossover) and variant (Mutation) operation, which by following the current search to find the optimal value to the global optimum. the algorithm for its easy implementation, high accuracy, and fast convergence advantages attracted academic attention, and in solving practical problems demonstrated its superiority.)
