利用MATLAB实现一维FDTD，希望对初学者有所帮助！(Using MATLAB to realize a d FDTD, hope it is helpful for beginners!)

In implementing this project, four types of gray wolves like Alpha, Beta, Delta and Omega is the use to simulate the leadership hierarchy in which the three main steps of the hunt, searching for prey, surrounded prey, and attack the bait, are implemented. The simulation results with particle swarm algorithm (PSO) is compared, show that the algorithm has achieved better performance Grey Wolf GWO.
