Parameters

x	other vector

constexpr PromotionTraits< field_type, typenameDenseVector< Other >::field_type >::PromotedType Dune::DenseVector< StaticArray< T > >::operator* ( const DenseVector< Other > & x ) const

inlineconstexprinherited

indefinite vector dot product \(\left (x^T \cdot y \right)\) which corresponds to Petsc's VecTDot

inlineconstexprinherited

vector space multiplication with scalar

we use enable_if to avoid an ambiguity, if the function parameter can be converted to field_type implicitly. (see FS#1457)

The function is only enabled, if the parameter is directly convertible to field_type.

inlineconstexprinherited

vector space add scalar to all comps

we use enable_if to avoid an ambiguity, if the function parameter can be converted to value_type implicitly. (see FS#1457)

The function is only enabled, if the parameter is directly convertible to value_type.

◆ operator-=()

constexpr std::enable_if< std::is_convertible< ValueType, value_type >::value, derived_type >::type & Dune::DenseVector< StaticArray< T > >::operator-= ( const ValueType & kk )

inlineconstexprinherited

vector space subtract scalar from all comps

we use enable_if to avoid an ambiguity, if the function parameter can be converted to value_type implicitly. (see FS#1457)

The function is only enabled, if the parameter is directly convertible to value_type.

◆ operator/=()

constexpr std::enable_if< std::is_convertible< FieldType, field_type >::value, derived_type >::type & Dune::DenseVector< StaticArray< T > >::operator/= ( const FieldType & kk )

inlineconstexprinherited

vector space division by scalar

we use enable_if to avoid an ambiguity, if the function parameter can be converted to field_type implicitly. (see FS#1457)

The function is only enabled, if the parameter is directly convertible to field_type.

◆ operator==()

template<class T >

bool Dune::Fem::StaticArray< T >::operator== ( const ThisType & other ) const

inline

comparison operator: checks for object identity, i.e. if this and other are the same objects in memory rather than containing the same data
