void Circle::evaluate_f	(	const double	t,
		const Vector< double > &	v,
		const double	tolerance,
		Vector< double > &	result
	)		const [inline, virtual]

evaluate the right--hand side f at (t,v), up to some tolerance (w.r.t. the ||.||_2 norm)

Implements MathTL::AbstractIVP< Vector< double > >.

void Circle::evaluate_ft	(	const double	t,
		const Vector< double > &	v,
		const double	tolerance,
		Vector< double > &	result
	)		const [inline, virtual]

evaluate the derivative f_t at (t,v), up to some tolerance (w.r.t. the ||.||_2 norm)

Implements MathTL::AbstractIVP< Vector< double > >.

void Circle::solve_ROW_stage_equation	(	const double	t,
		const Vector< double > &	v,
		const double	alpha,
		const Vector< double > &	y,
		const double	tolerancs,
		Vector< double > &	result
	)		const [inline, virtual]

Up to a given tolerance (w.r.t. the ||.||_2 norm), solve the special linear system

(alpha*I-J)x = y,

where J = f(t,v) is the (exact) Jacobian of f. This routine will primarily be used to solve the stage equations of an ROW-method.

Implements MathTL::AbstractIVP< Vector< double > >.
