Constructor Details

ComplexODEState

public ComplexODEState(double time,
 Complex[] primaryState)

Simple constructor.

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

Parameters:

time - time

primaryState - primary state at time

ComplexODEState

public ComplexODEState(double time,
 Complex[] primaryState,
 Complex[][] secondaryState)

Simple constructor.

Parameters:

time - time

primaryState - state at time

secondaryState - primary state at time (may be null)

Method Details

copy

protected Complex[][] copy(Complex[][] original)

Copy a two-dimensions array.

Parameters:

original - original array (may be null)

Returns:

copied array or null if original array was null

getTime

public double getTime()

Get time.

Returns:

time

getPrimaryStateDimension

public int getPrimaryStateDimension()

Get primary state dimension.

Returns:

primary state dimension

See Also:

• getSecondaryStateDimension(int)
• getCompleteStateDimension()

getPrimaryState

public Complex[] getPrimaryState()

Get primary state at time.

Returns:

primary state at time

See Also:

• getSecondaryState(int)
• getCompleteState()

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 ExpandableODE.addSecondaryEquations(SecondaryODE) (beware index 0 corresponds to primary state, secondary states start at 1)

Returns:

secondary state dimension

See Also:

• getPrimaryStateDimension()
• getCompleteStateDimension()

getSecondaryState

public Complex[] getSecondaryState(int index)

Get secondary state at time.

Parameters:

index - index of the secondary set as returned by ExpandableODE.addSecondaryEquations(SecondaryODE) (beware index 0 corresponds to primary state, secondary states start at 1)

Returns:

secondary state at time

See Also:

• getPrimaryState()
• getCompleteState()

getCompleteStateDimension

public int getCompleteStateDimension()

Return the dimension of the complete set of equations.

The complete set of equations correspond to the primary set plus all secondary sets.

Returns:

dimension of the complete set of equations

See Also:

• getPrimaryStateDimension()
• getSecondaryStateDimension(int)

getCompleteState

public Complex[] getCompleteState()

Get complete state at time.

Returns:

complete state at time, starting with primary state, followed by all secondary states in increasing index order
