说明：  粒子群优化算法是一种进化优化技术，源于对鸟群扑食的行为，是一种基于迭代的优化工具。此文件提供了基本粒子群算法、带压缩因子的粒子群算法、二阶粒子群算法、二阶振荡粒子群算法、权重改进的粒子群算法、混沌粒子群算法、基于杂交的粒子群算法、基于模拟退火的粒子群算法的MATLAB源代码。(PSO is an evolutionary optimization technique, derived from the behavior of the birds of prey, is based on iterative optimization tools. This document provides basic particle swarm algorithm, with a compression factor of the particle swarm algorithm, particle swarm optimization order, second order oscillating particle swarm algorithm, the weight particle swarm algorithm, chaotic particle swarm algorithm, based on hybrid particle swarm algorithm, based on Simulated annealing particle swarm optimization MATLAB source code.)

Automatic detection of eyes,nose and mouth in an image using inbuilt matlab functions

1.升余弦窗首尾8点数据值:12bit-> 1-1RAM_OUT_CNT_RN10 formal 采用移位相加的方式来取代相乘运算，节省资源。 (1 liter inclusive 8:00 cosine window data values​ ​ : 12bit-> 1-1RAM_OUT_CNT_RN10 formal using shift and add a way to replace multiplication, save resources.)

使用matlab程序编写的ACO算法过程，适合初学者(Use of matlab programming process of the ACO algorithms, suitable for beginners)

说明：  function [ret,x0,str,ts,xts]=s4(t,x,u,flag) s4 is the M-file description of the SIMULINK system named s4. The block-diagram can be displayed by typing: s4. SYS=s4(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

说明：  可实现三相交流电的24脉波整流，可以出图，请放心使用(It can realize 24-pulse rectifier of three-phase alternating current. The drawing can be drawn. Please feel free to use it.)
