I am not a mathematician and I don´t know much about it but i need help to fit an ellipse to a series of points and calculate its eccentricity. I have coordinates in the cartesian plane. I managed to do that using Matlab and the least Square approximation but i got many inconsistencies (transalting all the points in the plane led to different ellipse equation).
Serching the net I found out that Fitzgibbon, Pilu, Fisher fitting technique might be more reliable. Can someone who know better then me confirm that? Do you have a function in matlab i can enter to use that kind of fitting?
Thanks
