Sparse Vector</h1>
<h2><a name="mapped_vector" id="mapped_vector"></a>Mapped Vector</h2>
<h4>Description</h4>
<p>The templated class <code>mapped_vector<T, A></code> is
the base container adaptor for sparse vectors using element maps. For a
<em>n</em>-dimensional sparse vector and <em>0 <= i < n</em>
the non-zero elements <em>v</em><sub><em>i</em></sub> are mapped to
consecutive elements of the associative container, i.e. for
elements <em>k</em> =
<em>v</em><sub><em>i</em></sub><sub><sub><em>1</em></sub></sub>and
<em>k + 1 =
v</em><sub><em>i</em></sub><sub><sub><em>2</em></sub></sub>of the
container holds <em>i</em><sub><em>1</em></sub> <em><
i</em><sub><em>2</em></sub>.</p>
<h4>Example</h4>
<pre>
#include <boost/numeric/ublas/vector_sparse.hpp>
#include <boost/numeric/ublas/io.hpp>
int main () {
using namespace boost::numeric::ublas;
mapped_vector<double> v (3, 3);
for (unsigned i = 0; i < v.size (); ++ i)
v (i) = i;
std::cout << v << std::endl;
}

<h4>Notes</h4>
<p><a name="mapped_vector_1" id="mapped_vector_1">[1]</a> Supported
parameters for the adapted array are
<code>map_array<std::size_t, T></code> and
<code>map_std<std::size_t, T></code>. The latter is
equivalent to <code>std::map<std::size_t, T></code>.</p>

<p>The templated class <code>compressed_vector<T, IB, IA,

For a <em>n</em>-dimensional compressed vector and <em>0 <= i
< n</em> the non-zero elements <em>v</em><sub><em>i</em></sub>
are mapped to consecutive elements of the index and value
container, i.e. for elements <em>k</em> =
<em>v</em><sub><em>i</em></sub><sub><sub><em>1</em></sub></sub>and
<em>k + 1 =
v</em><sub><em>i</em></sub><sub><sub><em>2</em></sub></sub>of these
containers holds <em>i</em><sub><em>1</em></sub> <em><
i</em><sub><em>2</em></sub>.</p>

<h4>Description</h4>
<p>The templated class <code>coordinate_vector<T, IB, IA,
TA></code> is the base container adaptor for compressed vectors.
For a <em>n</em>-dimensional sorted coordinate vector and <em>0
<= i < n</em> the non-zero elements
<em>v</em><sub><em>i</em></sub> are mapped to consecutive elements
of the index and value container, i.e. for elements <em>k</em> =
<em>v</em><sub><em>i</em></sub><sub><sub><em>1</em></sub></sub>and
<em>k + 1 =
v</em><sub><em>i</em></sub><sub><sub><em>2</em></sub></sub>of these
containers holds <em>i</em><sub><em>1</em></sub> <em><
i</em><sub><em>2</em></sub>.</p>
<h4>Example</h4>
<pre>
#include <boost/numeric/ublas/vector_sparse.hpp>
#include <boost/numeric/ublas/io.hpp>
int main () {
using namespace boost::numeric::ublas;
coordinate_vector<double> v (3, 3);
for (unsigned i = 0; i < v.size (); ++ i)
v (i) = i;
std::cout << v << std::endl;
}
