      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 DimensionMismatchException

      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:
        `DimensionMismatchException` - if t is inconsistent with the function's free parameters or order
