Detailed Description

template<typename V>
class Dune::DenseVector< V >

Interface for a class of dense vectors over a given field.

Template Parameters

V	implementation class of the vector
T	value type
S	size type

V has to provide the following members:

T &       _access (size_type);
const T & _access (size_type) const;
size_type _size   () const;

Member Enumeration Documentation
