Method Summary

Modifier and Type	Method and Description
Complex[]	computeDerivatives(double t, Complex[] y) Get the current time derivative of the state vector.
int	getDimension() Get the dimension of the problem.
default void	init(double t0, Complex[] y0, double finalTime) Initialize equations at the start of an ODE integration.

Method Detail

getDimension

int getDimension()

Get the dimension of the problem.

Returns:

dimension of the problem

init

default void init(double t0,
                  Complex[] y0,
                  double finalTime)

Initialize equations at the start of an ODE integration.

This method is called once at the start of the integration. It may be used by the equations to initialize some internal data if needed.

The default implementation does nothing.

Parameters:

t0 - value of the independent time variable at integration start

y0 - array containing the value of the state vector at integration start

finalTime - target time for the integration

computeDerivatives

Complex[] computeDerivatives(double t,
                             Complex[] y)

Get the current time derivative of the state vector.

Parameters:

t - current value of the independent time variable

y - array containing the current value of the state vector

Returns:

time derivative of the state vector
