Detailed Description

template<class K>
class Dune::DynamicVector< K >

Construct a vector with a dynamic size.

Template Parameters

K	is the field type (use float, double, complex, etc)

Member Function Documentation

beforeBegin() [1/2]

Iterator Dune::DenseVector< DynamicVector< K > >::beforeBegin ( )

inlineinherited

Returns

an iterator that is positioned before the first entry of the vector.

beforeBegin() [2/2]

ConstIterator Dune::DenseVector< DynamicVector< K > >::beforeBegin ( ) const

inlineinherited

Returns

an iterator that is positioned before the first entry of the vector.

beforeEnd() [1/2]

Iterator Dune::DenseVector< DynamicVector< K > >::beforeEnd ( )

inlineinherited

Returns

an iterator that is positioned before the end iterator of the vector, i.e. at the last entry.

beforeEnd() [2/2]

ConstIterator Dune::DenseVector< DynamicVector< K > >::beforeEnd ( ) const

inlineinherited

Returns

an iterator that is positioned before the end iterator of the vector. i.e. at the last element

capacity()

template<class K >

size_type Dune::DynamicVector< K >::capacity ( ) const

inline

Number of elements for which memory has been allocated.

capacity() is always greater than or equal to size().

dot()

http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Vec/VecDot.html

Parameters

y	other vector

Returns

operator*()

PromotionTraits<field_type,typename DenseVector<Other>::field_type>::PromotedType Dune::DenseVector< DynamicVector< K > >::operator* ( const DenseVector< Other > &  y ) const

inlineinherited

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

http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Vec/VecTDot.html

Parameters

y	other vector

Returns
