Detailed Description

Performs a cubic interpolation; this class can be chosen via the options factory mechanism as a possible SpanInterpolator.

Details

This interpolator is hand-coded to be identical to the SpEC implementation used for SpEC CCE so that comparison results can be as close as possible for diagnostics.

get_clone()

std::unique_ptr< SpanInterpolator > intrp::CubicSpanInterpolator::get_clone ( ) const

inlineoverridevirtual

Produce a std::unique_ptr that points to a copy of *this`.

Implements intrp::SpanInterpolator.

interpolate()

double intrp::CubicSpanInterpolator::interpolate ( const gsl::span< const double > & source_points, const gsl::span< const double > & values, double target_point ) const

overridevirtual

Perform the interpolation of function represented by values at source_points to the requested target_point, returning the interpolation result.

Implements intrp::SpanInterpolator.

required_number_of_points_before_and_after()

size_t intrp::CubicSpanInterpolator::required_number_of_points_before_and_after ( ) const

inlineoverridevirtual

The number of domain points that should be both before and after the requested target point for best interpolation. For instance, for a linear interpolator, this function would return 1 to request that the target is between the two domain points passed to source_points.

Implements intrp::SpanInterpolator.
