QPSK的MATLAB仿真,仅供大家学习(QPSK the MATLAB simulation, for everyone to learn)

matlab 本身没有箭头功能，只有梯度，梯度不能精确，这是编写的箭头功能，可以精确定位箭头三维位置(matlab function itself has no arrows, only gradient, the gradient is not accurate, it is written in the arrow function, you can pinpoint the location of the arrow D)

Graph-Based Segmentation 是经典的图像分割算法，该算法是基于图的 贪心聚类 算法，实现简单，速度比较快，精度也还行。(Graph based Segmentation is a classical image Segmentation algorithms, the algorithm is Based on the figure of greedy clustering algorithm, speed is faster, and easy to implement precision is also ok.)

通过这一算法可以实现二维平面内无人机的路径规划。在该平面内存在已知的障碍，势场法通过给终点添加引力，对障碍增加斥力，使得无人机能够顺利的避障并到达终点。通过对传统势场法的改进，避免了无人机容易陷入极值的问题，使搜索更易实现。(Through this algorithm, the path planning of the UAV in the two-dimensional plane can be realized. There are known obstacles in the plane. The potential field method adds gravity to the terminal to increase the repulsion for obstacles, so that the UAV can avoid obstacles and reach the terminal smoothly. Through the improvement of the traditional potential field method, it avoids the problem that the UAV is easily trapped in the extreme value and makes the search more easy to be realized.)

This method handles the border by repeating the closest values to the point accessed. This is different from matlabs border handling.

包括了MATLAB相关的工具箱的详细介绍，是学习matlab的很好的参考资料。(Including the MATLAB toolbox related details is a good learning matlab reference.)
