Detailed Description

template<class Backend, class BasisTraits>
class Dune::PowerInterpolation< Backend, BasisTraits >

Meta-interpolation turning a scalar interpolation into vector-valued interpolation.

Template Parameters
BackendType of the scalar interpolation.
BasisTraitsTraits type of the corresponding PowerBasis.

Constructor & Destructor Documentation

◆ PowerInterpolation()

template<class Backend , class BasisTraits >
Dune::PowerInterpolation< Backend, BasisTraits >::PowerInterpolation ( const Backend &  backend_)
inline

Construct a PowerInterpolation.

Parameters
backend_Backend interpolation object to construct this object from. This object holds a reference to the backend object. This reference is also copied when this object is copied.

Member Function Documentation

◆ interpolate()

template<class Backend , class BasisTraits >
template<typename F , typename C >
void Dune::PowerInterpolation< Backend, BasisTraits >::interpolate ( const F &  ff,
std::vector< C > &  out 
) const
inline

Determine coefficients interpolating a given function.

Parameters
ffAn object supporting the expression ff.evaluate(x,y), where x is of type Traits::DomainLocal and y of the type Traits::Range. When f.evaluate(x,y) is evaluated, x will be a local coordinate, and the expression should set y to the function value at that position. The initial value of y should not be used.
outVector where to store the interpolated coefficients.
