public class LineBracketInterpolatorHermiteParabola
extends AbstractLineBracketInterpolatorPolynomial<DifferentiableUnivariateScalarFunction>

Interpolates using a parabola with two points, at least one of which must have slope information. If slope information is not present, then the interpolator will call the differentiate() method on the Evaluator.
