Description: NSEDFEllipsoid fits ellipsoid based on ellipse fitting method NESEDF.
Function alpha = NSEDFEllipsoid(X,Y,Z) gives the 10 parameter vector of the algebraic ellisoid fit to a(1)x^2+ a(2)y^2+ a(3)z^2+ a(4)xy+ a(5)xz+ a(6)yz+ a(7)x+ a(8)y+ a(9)z+ a(10) = 0， where X & Y & Z are lists of point coordinates and must be column vectors.
