set_points()

void aspect::Utilities::tk::spline::set_points	(	const std::vector< double > &	x,
		const std::vector< double > &	y,
		const bool	cubic_spline = true,
		const bool	monotone_spline = false
	)

Initialize the spline.

Parameters

x	X coordinates of interpolation points.
y	Values in the interpolation points.
cubic_spline	Whether to construct a cubic spline or just do linear interpolation
monotone_spline	Whether the cubic spline should be a monotone cubic spline. Requires cubic_spline to be set to true.

operator()()

double aspect::Utilities::tk::spline::operator()

(
