  public GaussIntegratorFactory()

Method Detail

• legendre

  public GaussIntegrator legendre(int numberOfPoints)

  Creates a Gauss-Legendre integrator of the given order. The call to the integrate method will perform an integration on the natural interval [-1 , 1].

  Parameters:

  numberOfPoints - Order of the integration rule.

  Returns:

  a Gauss-Legendre integrator.

• legendre

  public GaussIntegrator legendre(int numberOfPoints,
                         double lowerBound,
                         double upperBound)
                           throws NotStrictlyPositiveException

  Creates a Gauss-Legendre integrator of the given order. The call to the integrate method will perform an integration on the given interval.

  Parameters:

  numberOfPoints - Order of the integration rule.

  lowerBound - Lower bound of the integration interval.

  upperBound - Upper bound of the integration interval.

  Returns:

  a Gauss-Legendre integrator.

  Throws:

  NotStrictlyPositiveException - if number of points is not positive

• legendreHighPrecision

  public GaussIntegrator legendreHighPrecision(int numberOfPoints)
                                        throws NotStrictlyPositiveException

  Creates a Gauss-Legendre integrator of the given order. The call to the integrate method will perform an integration on the natural interval [-1 , 1].

  Parameters:

  numberOfPoints - Order of the integration rule.

  Returns:

  a Gauss-Legendre integrator.

  Throws:

  NotStrictlyPositiveException - if number of points is not positive

• legendreHighPrecision

  public GaussIntegrator legendreHighPrecision(int numberOfPoints,
                                      double lowerBound,
                                      double upperBound)
                                        throws NotStrictlyPositiveException

  Creates an integrator of the given order, and whose call to the integrate method will perform an integration on the given interval.

  Parameters:

  numberOfPoints - Order of the integration rule.

  lowerBound - Lower bound of the integration interval.

  upperBound - Upper bound of the integration interval.

  Returns:

  a Gauss-Legendre integrator.

  Throws:

  NotStrictlyPositiveException - if number of points is not positive

• hermite

  public SymmetricGaussIntegrator hermite(int numberOfPoints)

  Creates a Gauss-Hermite integrator of the given order. The call to the integrate method will perform a weighted integration on the interval \([-\infty, +\infty]\): the computed value is the improper integral of \(e^{-x^2}f(x)\) where \(f(x)\) is the function passed to the integrate method.

  Parameters:

  numberOfPoints - Order of the integration rule.

  Returns:

  a Gauss-Hermite integrator.
