unit_vector represents a canonical unit vector unit_vector represents a canonical unit vector. The k-th unit vector of dimension
holds 0 for every value
s.t.
and 1 when
. At construction, the value k is given after the dimension of the vector.

| 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) |
| Copy-constructor. | |
| 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). | |
| BOOST_UBLAS_INLINE const_pointer | find_element (size_type i) const |
| Return a const pointer to the element of index i. | |
| BOOST_UBLAS_INLINE const_reference | operator() (size_type i) const |

| 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. |
