粒子群算法的matlab实现，由主函数swarm和6个辅助函数：fitness（适应度函数）、congstrict(约束函数)、getNeighborIndex、getNeighborIndexVector、getNeighborIndexWithBestFitness、randint组成。其中fitness由使用者自行编写。-SO algorithm matlab realize, from the main function of swarm and six auxiliary functions: fitness (fitness function

Number), congstrict (constraint function), getNeighborIndex, getNeighborIndexVector,

getNeighborIndexWithBestFitness, randint composition. Compiled by the user which fitnessTo write.
