georegression.struct.curve.PolynomialQuadratic2D_F64

public class PolynomialQuadratic2D_F64
extends Object

Quadratic curve in 2D: f(x,y) = a + b·x + c·y + d·xy + e·x² + f·y².

NOTE: The coefficient order is the reverse of what you will find for sake of consistency as the order of the polynomial is increased.
