Use MATLAB to write a code about obstacle avoidance path planning, and use the plot function in MATLAB for visualization. ...

You can use the Path Planning Toolbox provided in MATLAB, which can implement automatic path planning. Among them, there are four different obstacle avoidance strategies: random obstacle avoidance, collision avoidance, adaptive trajectory tracking and minimum path planning. For specific implementation, please refer to the sample code in the MATLAB documentation, and use the plot function to visualize the results.
