    • evaluate

      void evaluate(double x, double delta, com.irurueta.algebra.Matrix result) throws EvaluationException
      Evaluates a single dimension function such as f(x) at provided point and returns the result.
      Parameters:
      x - point where function will be evaluated.
      delta - value to handle singularities. If the function has no singularities, or the singularities are “mild” (e.g., no worse than logarithmic), this can be ignored.
      result - matrix where function evaluation will be stored.
      Throws:
      EvaluationException - raised if something failed during the evaluation.

    • getRows

      int getRows()

      Returns:
      number of rows.

    • getColumns

      int getColumns()
      Gets number of columns of matrix result of function f.
      Returns:
      number of columns.
