Detailed Description

template<int mydim, int cdim, class GridImp>
class Dune::YaspGeometry< mydim, cdim, GridImp >

The general version that handles all codimensions but 0 and dim.

Template Parameters

mydim	the codimension
cdim	the coordinate dimension (NOT codim)

JacobianInverseTransposed

typedef std::conditional<dim==coorddim,DiagonalMatrix<ctype,dim>,FieldMatrix<ctype,coorddim,dim>>::type Dune::AxisAlignedCubeGeometry< GridImp::ctype , dim, coorddim >::JacobianInverseTransposed

inherited

Return type of jacobianInverseTransposed.

This is a fast DiagonalMatrix if dim==coorddim, and a FieldMatrix otherwise. The FieldMatrix will never contain more than one entry per column, hence it could be replaced by something more efficient.

JacobianTransposed

typedef std::conditional<dim==coorddim,DiagonalMatrix<ctype,dim>,FieldMatrix<ctype,dim,coorddim>>::type Dune::AxisAlignedCubeGeometry< GridImp::ctype , dim, coorddim >::JacobianTransposed

inherited

Return type of jacobianTransposed.

This is a fast DiagonalMatrix if dim==coorddim, and a FieldMatrix otherwise. The FieldMatrix will never contain more than one entry per row, hence it could be replaced by something more efficient.
