Member Function Documentation

apply()

template<typename Op >

void CG< Op >::apply ( Field< vector_type > &  in, Field< vector_type > &  out  )

inline

The apply() -member runs the full conjugate gradient The operators themselves have the same structure. The conjugate gradient operator is Hermitean, so there is no dagger().
