Detailed Description

template<class MI, class IMS, class... SPB>
class Dune::Functions::CompositePreBasis< MI, IMS, SPB >

A pre-basis for composite bases.

This pre-basis represents a composition of several given pre-bases. Its node type is a CompositeBasisNodes for the given subnodes.

Template Parameters
MIType to be used for global multi-indices
IMSAn IndexMergingStrategy used to merge the global indices of the child pre-bases
SPBThe child pre-bases
