<h4>1.1 <span class="Heading">Overview over this manual</span></h4>
<p>Chapter <a href="chap1_mj.html#X7DFB63A97E67C0A1"><span class="RefLink">1</span></a> is concerned with the technical details of installing and running this package. Chapter <a href="chap2_mj.html#X823150E97BE77525"><span class="RefLink">2</span></a> answers the question why and how the <strong class="pkg">GAP</strong> functionality concerning a sparse matrix type and gaussian algorithms was extended. The following chapters are concerned with the workings of the sparse matrix type (<a href="chap3_mj.html#X7901751583E1B976"><span class="RefLink">3</span></a>) and sparse Gaussian algorithms (<a href="chap4_mj.html#X86443AB17C0AD00C"><span class="RefLink">4</span></a>). Included is a documented list of the most important methods and functions needed to work with sparse matrices and the algorithms provided by the <strong class="pkg">Gauss</strong> package. Anyone interested in sourcecode should just check out the files in the <code class="file">gap/pkg/Gauss/gap/</code> folder (--> Appendix <a href="chapA_mj.html#X78EED4F77E698478"><span class="RefLink">A</span></a>).</p>
<h4>1.2 <span class="Heading">Installation of the <strong class="pkg">Gauss</strong> Package</span></h4>
<p>To install this package just extract the package's archive file to the GAP pkg/ directory. The Gauss package utilizes some C-code by Max Neunhoeffer that has to be compiled before you can load Gauss. To compile the code, first run ./configure. If the package is not installed in the pkg/ subdirectory of GAP's root directory you will need to provide the correct path to the latter. This will create a makefile. Complete the installation of the package by running <code class="code">make</code>. Recompiling the documentation is possible by the command <code class="code">make doc</code> in the Gauss directory, but this should not be necessary.</p>
<p>By default the <strong class="pkg">Gauss</strong> package is not automatically loaded by <strong class="pkg">GAP</strong> when it is installed. You must load the package with <code class="code">LoadPackage("Gauss");</code> before its functions become available. Please, send me an e-mail if you have any questions, remarks, suggestions, etc. concerning <strong class="pkg">Gauss</strong>. Also, I would like to hear about applications of this package.<br /> Simon Goertzen<br /></p>
