中文说明：matlab栅格法仿真，直接复制到matlab里面仿真就行。可以实现栅格法路径规划，用来生成初始的路径，此方法生成的路径的栅格简洁，可以实现良好的人机交互界面，有利于初学者对栅格法的理解与掌握栅格法的内容，可以实现良好的人机交互界面。
English Description：
Matlab grid method simulation, directly copied to Matlab inside the simulation on the line. It can realize the path planning of grid method, which is used to generate the initial path. The grid of the path generated by this method is simple, which can achieve a good human-computer interaction interface. It is conducive for beginners to understand and master the content of grid method, and can achieve a good human-computer interaction interface.
