Package georegression.struct.curve

Class PolynomialQuadratic1D_F64

java.lang.Object

georegression.struct.curve.PolynomialQuadratic1D_F64

All Implemented Interfaces:

PolynomialCurve_F64, MapFormattable

public class PolynomialQuadratic1D_F64
extends Object
implements PolynomialCurve_F64

Quadratic curve in 1D: f(x) = a + bx + c x².

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