Constructor Detail

FieldODEStateAndDerivative

public FieldODEStateAndDerivative(T time,
                                  T[] state,
                                  T[] derivative)

Simple constructor.

Calling this constructor is equivalent to call FieldODEStateAndDerivative(time, state, derivative, null, null).

Parameters:

time - time

state - state at time

derivative - derivative of the state at time

FieldODEStateAndDerivative

public FieldODEStateAndDerivative(T time,
                                  T[] state,
                                  T[] derivative,
                                  T[][] secondaryState,
                                  T[][] secondaryDerivative)

Simple constructor.

Parameters:

time - time

state - state at time

derivative - derivative of the state at time

secondaryState - state at time (may be null)

secondaryDerivative - derivative of the state at time (may be null)

Method Detail

getDerivative

public T[] getDerivative()

Get derivative of the main state at time.

Returns:

derivative of the main state at time

getSecondaryDerivative

public T[] getSecondaryDerivative(int index)

Get derivative of the secondary state at time.

Parameters:

index - index of the secondary set as returned by FieldExpandableODE.addSecondaryEquations(FieldSecondaryEquations) (beware index 0 corresponds to main state, additional states start at 1)

Returns:

derivative of the secondary state at time
