public interface UnivariateDifferentiableFunction
extends UnivariateFunction

Interface for univariate functions derivatives.

This interface represents a simple function which computes both the value and the first derivative of a mathematical function. The derivative is computed with respect to the input variable.

                          throws MathIllegalArgumentException

Simple mathematical function.

UnivariateDifferentiableFunction classes compute both the value and the first derivative of the function.

Parameters:

t - function input value

Returns:

function result

Throws:

MathIllegalArgumentException - if t does not fulfill functions constraints (argument out of bound, or unsupported derivative order for example)
