Function Documentation

static int f	(	realtype	t,
		N_Vector	y,
		N_Vector	ydot,
		void *	f_data
	)			[static]

Wrap function for solver f for computing of in .

This function makes the bridge between the Sundials ODE-solver and the evaluation function compute_state_dot()

Parameters:

	t	: time
	y	: state () in the datatype needed by the solver
	ydot	: evaluation output ()
	*f_data,:	pointer of type void, pointing on the ODE_data type struct containing all the model's data

Returns:

: 0 (no meaning yet <=> no integration error handling yet!!!)
