public class EllipseQuadratic_F64
extends ConicGeneral_F64

In general quadratic form, an ellipse is described by 6-coefficients:
F(x,y) = a*x^2 + 2*b*x*y + c*y^2 + 2*d*x + 2*e*y + f = 0
a*c - b*b > 0
where [a,b,c,d,e,f] are the coefficients and [x,y] is the coordinate of a point on the ellipse.

NOTE: these parameters are unique only up to a scale factor.
