<p>This module provides an interface to the <a href="http://pastix.gforge.inria.fr/">PaSTiX</a> library. PaSTiX is a general <b>supernodal</b>, <b>parallel</b> and <b>opensource</b> sparse solver. It provides the two following main factorization classes:</p>
<ul>
<li>class PastixLLT : a supernodal, parallel LLt Cholesky factorization.</li>
<li>class PastixLDLT: a supernodal, parallel LDLt Cholesky factorization.</li>
<li>class PastixLU : a supernodal, parallel LU factorization (optimized for a symmetric pattern).</li>
</ul>
<div class="fragment"><div class="line">* #include <Eigen/PaStiXSupport></div>
<div class="line">* </div>
</div><!-- fragment --><p>In order to use this module, the PaSTiX headers must be accessible from the include paths, and your binary must be linked to the PaSTiX library and its dependencies. The dependencies depend on how PaSTiX has been compiled. For a cmake based project, you can use our FindPaSTiX.cmake module to help you in this task. </p>
