Member Enumeration Documentation

Enumerator
DEFAULT_BC	quadratic function over corresponding interval (first/last)
FIRST_BC	imposed first derivative at corresponding endpoint (left/right)
SECOND_BC	imposed second derivative at corresponding endpoint (left/right)

chrono::ChCubicSpline::ChCubicSpline	(	const std::vector< double > &	t,
		const std::vector< double > &	y
	)

Construct a cubic spline y = y(t).

It is assumed that the t values are sorted in ascending order.

void chrono::ChCubicSpline::SetLeftBC	(	BCType	type,
		double	val
	)

Set the boundary condition at the left endpoint.

The specified value is ignored if type = DEFAULT_BC.

void chrono::ChCubicSpline::SetRightBC	(	BCType	type,
		double	val
	)

Set the boundary condition at the right endpoint.

The specified value is ignored if type = DEFAULT_BC.
