            public double getData(int index)

            {

                        return data[index];

            }

            public void setData(int index, double value)

            {

                        data[index] = value;

            }

            public double[ ] getData( )

            {

                        return data;

            }

            public void setData(double[ ] values)

            {

                        data = new double[values.length];

                        System.arraycopy(values, 0, data, 0, values.length);

            }

}
