Constructor Detail

FieldODEState

public FieldODEState(T time,
                     T[] state)

Simple constructor.

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

Parameters:

time - time

state - state at time

FieldODEState

public FieldODEState(T time,
                     T[] state,
                     T[][] secondaryState)

Simple constructor.

Parameters:

time - time

state - state at time

secondaryState - state at time (may be null)

Method Detail

getTime

public T getTime()

Get time.

Returns:

time

getStateDimension

public int getStateDimension()

Get main state dimension.

Returns:

main state dimension

getState

public T[] getState()

Get main state at time.

Returns:

main state at time

getNumberOfSecondaryStates

public int getNumberOfSecondaryStates()

Get the number of secondary states.

Returns:

number of secondary states.

getSecondaryStateDimension

public int getSecondaryStateDimension(int index)

Get secondary state dimension.

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:

secondary state dimension

getSecondaryState

public T[] getSecondaryState(int index)

Get 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:

secondary state at time
