| * <p> |
| * This package holds the main interfaces and basic building block classes |
| * dealing with differentiation. |
| * The core class is {@link org.apache.commons.math4.legacy.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.math4.legacy.analysis.differentiation.UnivariateDifferentiableFunction |
| * UnivariateDifferentiableFunction} interface. Any differentiable function should implement this |
| * interface. |
| * </p> |
| * <p> |
| * The {@link org.apache.commons.math4.legacy.analysis.differentiation.UnivariateFunctionDifferentiator |
| * UnivariateFunctionDifferentiator} interface defines a way to differentiate a simple {@link |
| * org.apache.commons.math4.legacy.analysis.UnivariateFunction UnivariateFunction} and get a {@link |
| * org.apache.commons.math4.legacy.analysis.differentiation.UnivariateDifferentiableFunction |
| * UnivariateDifferentiableFunction}. |
| * </p> |
| * <p> |
| * Similar interfaces also exist for multivariate functions and for vector or matrix valued functions. |
