/**

* <p>
* This package holds the main interfaces and basic building block classes
* dealing with differentiation.
* The core class is {@link org.apache.commons.math3.analysis.differentiation.DerivativeStructure
* DerivativeStructure} which holds the value and the differentials of a function. This class
* handles some arbitrary number of free parameters and arbitrary differentiation order. It is used
* both as the input and the output type for the {@link
* org.apache.commons.math3.analysis.differentiation.UnivariateDifferentiableFunction
* UnivariateDifferentiableFunction} interface. Any differentiable function should implement this
* interface.
* </p>
* <p>
* The {@link org.apache.commons.math3.analysis.differentiation.UnivariateFunctionDifferentiator
* UnivariateFunctionDifferentiator} interface defines a way to differentiate a simple {@link
* org.apache.commons.math3.analysis.UnivariateFunction UnivariateFunction} and get a {@link
* org.apache.commons.math3.analysis.differentiation.UnivariateDifferentiableFunction
* UnivariateDifferentiableFunction}.
* </p>
* <p>
* Similar interfaces also exist for multivariate functions and for vector or matrix valued functions.
* </p>
