• HarmonicOscillator.Parametric

  public HarmonicOscillator.Parametric()

Method Detail

• value

  public double value(double x,
             double... param)
               throws NullArgumentException,
                      DimensionMismatchException

  Computes the value of the harmonic oscillator at x.

  Specified by:

  value in interface ParametricUnivariateFunction

  Parameters:

  x - Value for which the function must be computed.

  param - Values of norm, mean and standard deviation.

  Returns:

  the value of the function.

  Throws:

  NullArgumentException - if param is null.

  DimensionMismatchException - if the size of param is not 3.

• gradient

  public double[] gradient(double x,
                  double... param)
                    throws NullArgumentException,
                           DimensionMismatchException

  Computes the value of the gradient at x. The components of the gradient vector are the partial derivatives of the function with respect to each of the parameters (amplitude, angular frequency and phase).

  Specified by:

  gradient in interface ParametricUnivariateFunction

  Parameters:

  x - Value at which the gradient must be computed.

  param - Values of amplitude, angular frequency and phase.

  Returns:

  the gradient vector at x.

  Throws:

  NullArgumentException - if param is null.

  DimensionMismatchException - if the size of param is not 3.
