	<p>
  Having made all these nice AOs, you will be keen to save them to disk. You'll
  be delighted to hear that this is easy.
</p>
<p>
  To file formats are supported by LTPDA: the MATLAB binary MAT format, and
  an XML file format. The choice is made by the file extension.
</p>
<div class="fragment"><pre>
  save(a1, <span class="string">'foo.xml'</span>);
  save(a1, <span class="string">'foo.mat'</span>);
</pre></div>
<p>
  To load the files again, you use the AO constructor:
</p>
<div class="fragment"><pre>
  a1 = ao(<span class="string">'foo.xml'</span>);
  a2 = ao(<span class="string">'foo.mat'</span>);
</pre></div>
<p>
  That's all there is to it.
</p>
<p>
  To load files on the workbench, you use the relevant constructor block. For example, to load
  an AO XML file from disk, use the <tt>ao</tt> constructor with the parameter set "From XML File"
  (or "From MAT File" to load from a MAT file). This parameter set has one default parameter: <tt>FILENAME</tt>.
  If you double click the cell corresponding to the parameter value you will be presented with a 'load file' dialog
  from which you can choose the file to load.
</p>
<p>
  To save files from within the workbench, use the <tt>save</tt> block. The parameter list and key is the same.
  The only difference will be you will be presented with a 'save file' dialog box when editing the parameter value.
</p>
<p>
  The following pipeline shows the load and save in action:
