Detailed Description

template<class RadialExtrapolationRule>
class SplineInterpolatorRTheta< RadialExtrapolationRule >

A class for interpolating a function using splines in polar coordinates.

Template Parameters

RadialExtrapolationRule The extrapolation rule applied at the outer radial bound.

Constructor & Destructor Documentation

template<class RadialExtrapolationRule >

SplineInterpolatorRTheta< RadialExtrapolationRule >::SplineInterpolatorRTheta	(	SplineRThetaBuilder_host const &	builder,
		evaluator_type const &	evaluator
	)

inline

Create a spline interpolator object.

Parameters

[in]	builder	An operator which builds spline coefficients from the values of a function at known interpolation points.
[in]	evaluator	An operator which evaluates the value of a spline at requested coordinates.

	)		const

inlineoverride

Approximate the value of a function at a set of polar coordinates using the current values at a known set of interpolation points.

Parameters

[in,out]	inout_data	On input: an array containing the value of the function at the interpolation points. On output: an array containing the value of the function at the coordinates.
[in]	coordinates	The polar coordinates where the function should be evaluated.

Returns: A reference to the inout_data array containing the value of the function at the coordinates.
