Template Function combigrid::hierarchize_biorthogonal_boundary_kernel

Function Documentation

template<typename FG_ELEMENT, bool periodic = false>
inline void combigrid::hierarchize_biorthogonal_boundary_kernel(FG_ELEMENT *data, LevelType lmax, LevelType lmin = 0)

mass-conserving hierarchization with biorthogonal wavelet and scaling function; the hierarchical basis function W corresponds to the wavelet [-1/8 -1/4 3/4 -1/4 -1/8], cf. Cohen-Daubechies-Feauveau

Template Parameters:

FG_ELEMENT – data type on grid

Parameters:

  • data – pointer to data begin

  • lmax – maximum level

  • lmin – minimum level (if > 0, hierarchization is not performed all the way down)
