Parameters

x	other vector

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.

operator-=()

std::enable_if< std::is_convertible< ValueType, value_type >::value, derived_type >::type & Dune::DenseVector< DynamicReferenceVector< K, A > >::operator-= ( const ValueType &  kk )

inlineinherited

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/=()

std::enable_if< std::is_convertible< FieldType, field_type >::value, derived_type >::type & Dune::DenseVector< DynamicReferenceVector< K, A > >::operator/= ( const FieldType &  kk )
