Detailed Description

template<typename ValueType>
class gko::multigrid::EnableMultigridLevel< ValueType >

The EnableMultigridLevel gives the default implementation of MultigridLevel with composition and provides set_multigrid_level function.

A class inherit from EnableMultigridLevel should use the this->get_compositions()->apply(...) as its own apply, which represents op(b) = prolong(coarse(restrict(b))).
