/**
 * Some checks for the getCoefficients() method.
 *//*from   www  .j  ava  2 s .c  o  m*/
@Test
public void testGetCoefficients() {
    PolynomialFunction2D f = new PolynomialFunction2D(new double[] { 1.0, 2.0 });
    double[] c = f.getCoefficients();
    assertTrue(Arrays.equals(new double[] { 1.0, 2.0 }, c));

    // make sure that modifying the returned array doesn't change the
    // function
    c[0] = 99.9;
    assertTrue(Arrays.equals(new double[] { 1.0, 2.0 }, f.getCoefficients()));
}
