boost::numeric::ublas::unit_vector< T, ALLOC > Class Template Reference

unit_vector represents a canonical unit vector unit_vector represents a canonical unit vector. The k-th unit vector of dimension $n$ holds 0 for every value $u_i$ s.t. $i \neq k$ and 1 when $i=k$. At construction, the value k is given after the dimension of the vector. More...

Public Member Functions

BOOST_UBLAS_INLINE unit_vector ()
 Simple constructor with dimension and index 0.
BOOST_UBLAS_INLINE unit_vector (size_type size, size_type index=0)
 Constructor of unit_vector.
BOOST_UBLAS_INLINE unit_vector (const unit_vector &v)
BOOST_UBLAS_INLINE size_type size () const
 Return the size (dimension) of the vector.
BOOST_UBLAS_INLINE size_type index () const
 Return the order of the unit vector.
BOOST_UBLAS_INLINE void resize (size_type size, bool=true)
 Resize the vector. The values are preserved by default (i.e. the index does not change).

Detailed Description

template<class T, class ALLOC>
class boost::numeric::ublas::unit_vector< T, ALLOC >

Template Parameters:
T is the type of elements in the vector. They must be 0 and 1 assignable in order for the vector to have its unit-vector semantic.
ALLOC a specific allocator can be specified if needed. Most of the time this parameter is omited.
