实例，简单的介绍了matlab的基本知识，适合初学者，希望对大家有帮助(Instance, a simple introduction to the basics of matlab, suitable for beginners, we want to help)

保证全局收敛的随机微粒群算法。当最优粒子的解无进化，则对其位置、速度进行变异，而使算法不致过早收敛，只要迭代次数足够，算法保证全局收敛。(ensure global convergence of random particle swarm algorithm. When the optimal solution without particles of evolution, its location, speed variation, which might not premature convergence algorithm, as long as sufficient number of iterative algorithm to ensure global convergence.)
