All Implemented Interfaces:: PolynomialCurve_F64

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.
