Hello, I have an interesting problem and I hope it is possible to solve it using sage. I have a scanned digitized graph of a magnetic hysteresis loop. That is, I have a list of points [(H0,B0),(H1,B1)....(Hn,Bn)] however, the points are not ordered in any meaningful way. In order to calculate the hysteresis loss, which is the area enclosed by the loop, I need to somehow convert the list of points into a polyngon (clockwise or counterclockwise). I am not sure about the definition of this polygon. Perhaps it is a simple polygon (not intersecting) which includes all the points in the list as vertices and encloses the maximum area.
Is there some algorithm that does it ? Is there such a thing in sage ?
