§ 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
xX coordinates of interpolation points.
yValues in the interpolation points.
cubic_splineWhether to construct a cubic spline or just do linear interpolation
monotone_splineWhether the cubic spline should be a monotone cubic spline. Requires cubic_spline to be set to true.

§ operator()()

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

Evaluate spline at point x.
