Package georegression.struct.curve

Class PolynomialCubic1D_F64

java.lang.Object

georegression.struct.curve.PolynomialCubic1D_F64

All Implemented Interfaces:

PolynomialCurve_F64, MapFormattable

public class PolynomialCubic1D_F64
extends Object
implements PolynomialCurve_F64

Quadratic curve in 1D: f(x) = a + bx + c x² + d x³

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