Detailed Description

template<class D, class R, int d>
class Dune::P0LocalBasis< D, R, d >

\brief Constant shape function

Defines the constant scalar shape function in d dimensions. Is
valid on any type of reference element.

\tparam D Type to represent the field in the domain.
\tparam R Type to represent the field in the range.
\tparam d Domain dimension

◆ partial()

template<class D , class R , int d>
void Dune::P0LocalBasis< D, R, d >::partial ( const std::array< unsigned int, d > &  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
orderOrder of the partial derivatives, in the classic multi-index notation
inPosition where to evaluate the derivatives
[out]outReturn value: the desired partial derivatives
