levyPSO是一个函数,它使用基于levy特征分布的随机PSO算法，搜索n维函数的全局最小值。-[gbest, xb] = levyPSO(@func, vars) is a function that searches for the global minimum of an n-Dimensional function defined in func using the PSO algorithm based on Levy distribution randomization.

用matlab实现levy概率分布，并作图，用于进化算法中调整步长(Using MATLAB to realize levy probability distribution and make a map for adjusting step size in evolutionary algorithm)
