中文说明：资源描述曲线曲率的计算，其中数据是自己带的，如果要更改数据的话，自己导入mat文件，直接加载，mat文件里边必须有曲线的上的点的坐标，以及每个线段的左右两点的坐标矩阵，好好看看里边的说明，你就会清楚原来数据的结构，很适合初学者，招了很长时间才找到的适合分享
English Description：
Application backgroundCurve curvature calculation, the data is their own, if you want to change the data, then import mat file, directly loaded, mat file must have the coordinates of the points on the curve, as well as the coordinates of each line around two points, a good look inside the structure, you will know the structure of the original data, it is suitable for beginners, a very long time to find the right to share
