    Method
    Description
    void
    evaluate(double[] point, double[] result)
    Evaluates a multi variate function such as f1(x1, x2, ...), f2(x1, x2, ...) at provided multidimensional point and returns the result as a vectorial value
    int
    getNumberOfVariables()
    Number of variables of function f.

  • Method Details

    • evaluate

      void evaluate(double[] point, double[] result) throws EvaluationException
      Evaluates a multi variate function such as f1(x1, x2, ...), f2(x1, x2, ...) at provided multidimensional point and returns the result as a vectorial value
      Parameters:
      point - multidimensional point where function will be evaluated
      result - vector where function evaluation will be stored
      Throws:
      EvaluationException - if something failed during the evaluation

    • getNumberOfVariables

      int getNumberOfVariables()
      Number of variables of function f. This is equal to the length of the array obtained as function evaluations. Hence, a function f can be expressed as f = [f1, f2, ... fN], and the number of variables would be N
      Returns:
      number of variables of function f
