      void evaluateGradient(double[] params, double[] result) throws EvaluationException
      Computes/retrieves a multidimensional function's gradient.
      Parameters:
      params - Array of input parameters of a multidimensional function
      result - Array containing estimated gradient. This parameter must contain an already instantiated array having the same length as params. The values of this gradient will be rewritten after executing this method and this array will contain the estimated or evaluated gradient
      Throws:
      EvaluationException - Raised if something fails.
