Class ScalarSecondOrderDifferentiator

  • All Implemented Interfaces:

    public class ScalarSecondOrderDifferentiator
    extends Object
    implements Differentiator<Double,​Double,​Double>
    Differentiates a scalar function with respect to its argument using finite difference.

    For a function $y = f(x)$ where $x$ and $y$ are scalars, this class produces a function that returns the second derivative value for each point, i.e., $\frac{d^2 f}{dx^2}$.
