<h2>Release 1.52.0</h2>
|
|
|
|
<h3>improvements</h3>
|
|
|
|
<ul>
|
|
<li><a href="https://svn.boost.org/trac/boost/ticket/4024">[4024]</a> improve performance of inplace_solve</li>
|
|
<li><a href="https://svn.boost.org/trac/boost/ticket/6511">[6511]</a> Division by scalar should use enable_if<></li>
|
|
<li><a href="https://svn.boost.org/trac/boost/ticket/7297">[7297]</a> Make the free functions 'num_columns' and 'num_rows' support the uBLAS traits system and better work with expression types</li>
|
|
</ul>
|
|
|
|
<h3>bug fixes</h3>
|
|
|
|
<ul>
|
|
<li><a href="https://svn.boost.org/trac/boost/ticket/7296">[7296]</a> fixes and improvements to test utility functions</li>
|
|
<li><a href="https://svn.boost.org/trac/boost/ticket/7363">[7363]</a> fixed coordinate_matrix::sort() for gcc 4.7 and others</li>
|
|
</ul>

<h2>Release 1.43.0</h2>
|
|
|
|
<h3>bug fixes</h3>
|
|
|
|
<ul>
|
|
<li><a href="https://svn.boost.org/trac/boost/ticket/3968">[3968]</a> fixed coordinate_matrix sort problem on MSVC10
|
|
</li>
|
|
<li><a href="https://svn.boost.org/trac/boost/ticket/3539">[3539]</a>
|
|
changed computation of <code>norm_inf</code> for complex types to match
|
|
mathematical definition. <br />
|
|
<b>Note:</b> This might cause a performance drop
|
|
because now <code>std::abs(z)</code> is called for each vector element.
|
|
The old implementation used <code>std::max(std::abs(real(z)),std::abs(imag(z))</code>.
|
|
Further <code>norm_inf</code> and <code>norm_1</code> will now return
|
|
the same values for complex vector.
|
|
</li>
|
|
<li><a href="https://svn.boost.org/trac/boost/ticket/3501">[3501]</a> Moved free functions in <code>concepts.hpp</code> into anonymous namespace.
|
|
</li>
|
|
</ul>
|
|
|
|
<h2>Release 1.41.1</h2>
|
|
|
|
<h3>new features</h3>
|
|
|
|
<ul>
|
|
<li>Move semantics of vector/matrix container assignments have been
|
|
implemented. They can be enabled by setting
|
|
BOOST_UBLAS_MOVE_SEMANTICS. More details are on the <a
|
|
href="options.html">preprocessor options page</a>.
|
|
</li>
|
|
<li>Introduce new free functions. See <a href="https://svn.boost.org/trac/boost/ticket/3449" target="_blank">[3449]</a>,
|
|
