initialize()

auto initialize	(	double	tstart,
		VectorConstRef	y
	)		-> void

Initializes the ODE solver.

This method should be invoked whenever the user intends to make a call to DaeSolver::integrate.

Parameters

tstart	The start time of the integration.
y	The initial values of the variables

integrate() [1/2]

auto integrate	(	double &	t,
		VectorRef	y
	)		-> void

Integrate the ODE performing a single step.

Parameters

[in,out]	t	The current time of the integration as input, the new current time as output
[in,out]	y	The current variables as input, the new current variables as output

integrate() [2/2]

auto integrate	(	double &	t,
		VectorRef	y,
		double	tfinal
	)		-> void

Integrate the ODE performing a single step not going over a given time.

Parameters

[in,out]	t	The current time of the integration as input, the new current time as output
[in,out]	y	The current variables as input, the new current variables as output
	tfinal	The final time that the integration must satisfy

solve()

auto solve	(	double &	t,
		double	dt,
		VectorRef	y
	)		-> void

Solve the ODE equations from a given start time to a final one.

Parameters

[in,out]	t	The current time of the integration as input, the new current time as output
	dt	The value of the time step
[in,out]	y	The current variables as input, the new current variables as output
