          DerivativeStructure value(DerivativeStructure[] point)
                                    throws MathIllegalArgumentException

      Compute the value for the function at the given point.
      Parameters:
        `point` - Point at which the function must be evaluated.
      Returns:
        the function value for the given point.
      Throws:
        `MathIllegalArgumentException` - if `point` does not satisfy the function's constraints (wrong dimension, argument out of bound, or unsupported derivative order for example)
