I have a series of points whose coordinates are as follows
pts_x = 3 4 5 6 7 8 2 3 8 9 2 9 2 9 2 9 2 9 2 3 8 9 3 4 5 6 7 8
pts_y = 2 2 2 2 2 2 3 3 3 3 4 4 5 5 6 6 7 7 8 8 8 8 9 9 9 9 9 9
If I directly connect them following the current order, I get
But actually, I need a polygon. In order to re-ordere the points so that connecting them gives me a closed polygon, I come up with a solution that sorts the points in such a way that only one of x and y coordinates differs between two adjacent points.
How should I do this? I am in MATLAB.
