Detailed Description

template<class coef_tt, class index_tt = ptrdiff_t>
class Interpolation< coef_tt, index_tt >

Class for interpolation (set of indices in some array and coefficients).

Indices and coefficients are recorded in a vector This vector could be stored in this class or in some external class, which records other interpolations to this vector as well (see InterpPacker) coef_tt is type for interpolation coefficients (for example, double or complex) index_t is type for array indexation (int for 32-bit architecture)

Member Function Documentation

remap()

template<class coef_tt , class index_tt = ptrdiff_t>

int Interpolation< coef_tt, index_tt >::remap ( const std::map< index_t, index_t > &  cmap )

inline

Calculates buffer indices from mesh indices indices according to the map.

Unfound indices are not changed.

Returns

the number of unfound indices
