Detailed Description

template<class D, class R, int dim>
class Dune::Q1LocalBasis< D, R, dim >

Lagrange shape functions of order 1 on the reference cube.

Also known as \(Q^1\).

Template Parameters

D	Type to represent the field in the domain.
R	Type to represent the field in the range.
dim	Dimension of the cube \nosubgrouping

void Dune::Q1LocalBasis< D, R, dim >::partial ( const std::array< unsigned int, dim > &  order, const typename Traits::DomainType &  in, std::vector< typename Traits::RangeType > &  out  ) const

inline

Evaluate partial derivatives of any order of all shape functions.

Parameters

	order	Order of the partial derivatives, in the classic multi-index notation
	in	Position where to evaluate the derivatives
[out]	out	Return value: the desired partial derivatives
