Member Function Documentation

◆ interpolate()

template<typename F , typename C >
void Dune::InterpolationInterface::interpolate ( const F &  f,
std::vector< C > &  out 
) const

Determine coefficients interpolating a given function.

Parameters
fAn object supporting the expression f.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.
