matlab的行波法算法实现。可以验证simulink仿真时候产生的行波故障测距(Matlab algorithm for traveling wave method. The traveling wave fault location can be verified by Simulink simulation.)

说明：  改进的差分粒子群算法，并用于求函数极值，程序中分别于DE PSO 蛙跳进行对比，结果显示，改进的差分粒子群更好(The improved Differential Particle Swarm Optimization (DPSO) algorithm is used to find the function extremum. The program is compared with DE PSO frog jump, and the results show that the improved DPSO is better.)
