Detailed Description

template<class IMS, class SPB, std::size_t C>
class Dune::Functions::PowerPreBasis< IMS, SPB, C >

A pre-basis for power bases.

This pre-basis represents a power of a given pre-basis. Its node type is a PowerBasisNodes for the given subnode.

Template Parameters
IMSAn IndexMergingStrategy used to merge the global indices of the child factories
SPBThe child pre-basis
CThe exponent of the power node
