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.

Compute the value for the function.

Type Parameters:

T - the type of the field elements

Parameters:

x - the point for which the function value should be computed

Returns:

the value

Throws:

MathIllegalArgumentException - if x does not satisfy the function's constraints (argument out of bound, or unsupported derivative order for example)
