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.

      <T extends Derivative<T>> T value(T x) throws MathIllegalArgumentException
      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)
