<h2>Overview</h2>
Eigen is a C++ template library for vector and matrix math, a.k.a. linear algebra. It aims to concile speed, ease of use, and completeness.
<a name="license"></a>
<h2>License</h2>
Eigen is distributed under the GPL, version 2 or later, but with an <a href="#exception">exception allowing any software to use it</a>. Thus, to the question
"Can my own project use Eigen?", the answer is a definite <b>yes</b>.
Eigen's <a href="#exception">exception</a> is modeled after the one of the GNU C++ Standard Library, but is simpler and more liberal.
This is similar to the LGPL in spirit. The reason why we don't use the LGPL is that, as of version 2, it doesn't make sense for a pure template library like Eigen, where all the code is in headers.
<a name="features"></a>
<h2>Features</h2>
WARNING: this alpha release is NOT feature complete -- far from it! It contains only the Core module, while several other modules are planned.
<ul>
<li>Add items</li>
<li>Add more items</li>
</ul>

<a name="download"></a>
<h2>Download</h2>
The source code of the latest release is here: <a href="http://download.tuxfamily.org/eigen/eigen-2.0-alpha1.tar.gz">eigen-2.0-alpha1.tar.gz</a><br/>
Alternatively, you can checkout the development tree by anonymous svn, by doing:
<pre>svn co svn://anonsvn.kde.org/home/kde/branches/work/eigen2</pre>
or view it online at this address:
<a href="http://websvn.kde.org/branches/work/eigen2">http://websvn.kde.org/branches/work/eigen2</a>
<a name="kde"></a>
<h2>Relation to KDE</h2>
First of all: Eigen doesn't have any dependency. In particular, it doesn't depend on any part of KDE or on Qt.<br/>
Eigen is part of the KDE project, in the sense that:
<ul>
<li>Its <a href="http://websvn.kde.org/trunk/kdesupport/eigen/">development tree</a> is hosted in the <a href="http://websvn.kde.org">KDE repository</a>.</li>
<li>It has been founded by, and is developed by KDE people.</li>
<li>It has originally been designed for the needs of KDE applications, especially <a href="http://edu.kde.org/kalzium">Kalzium</a>.</li>
</ul>
However, we quickly realized that Eigen could be useful for non-KDE projects, whence our decision to make sure that it has no dependency on KDE or Qt.
Although Eigen itself doesn't have any dependency, the unit-tests require Qt.

// with other works to produce a work based on this file, this file does not
// by itself cause the resulting work to be covered by the GNU General Public
// License. This exception does not invalidate any other reasons why a work
// based on this file might be covered by the GNU General Public License.
