Constructor Details

FieldODEStateAndDerivative

public FieldODEStateAndDerivative(T time,
 T[] primaryState,
 T[] primaryDerivative)

Simple constructor.

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

Parameters:

time - time

primaryState - primary state at time

primaryDerivative - derivative of the primary state at time

FieldODEStateAndDerivative

public FieldODEStateAndDerivative(T time,
 T[] primaryState,
 T[] primaryDerivative,
 T[][] secondaryState,
 T[][] secondaryDerivative)

Simple constructor.

Parameters:

time - time

primaryState - primary state at time

primaryDerivative - derivative of the primary state at time

secondaryState - state at time (may be null)

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

Method Details

getPrimaryDerivative

public T[] getPrimaryDerivative()

Get derivative of the primary state at time.

Returns:

derivative of the primary state at time

See Also:

• getSecondaryDerivative(int)
• getCompleteDerivative()

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(FieldSecondaryODE) (beware index 0 corresponds to primary state, secondary states start at 1)

Returns:

derivative of the secondary state at time

See Also:

• getPrimaryDerivative()
• getCompleteDerivative()

getCompleteDerivative

public T[] getCompleteDerivative()

Get complete derivative at time.

Returns:

complete derivative at time, starting with primary derivative, followed by all secondary derivatives in increasing index order
