41 Having made all these nice AOs, you will be keen to save them to disk. You'll
42 be delighted to hear that this is easy.
43 </p>
44 <p>
45 To file formats are supported by LTPDA: the MATLAB binary MAT format, and
46 an XML file format. The choice is made by the file extension.
47 </p>
48 <div class="fragment"><pre>
49 save(a1, <span class="string">'foo.xml'</span>);
50 save(a1, <span class="string">'foo.mat'</span>);
51 </pre></div>
52 <p>
53 To load the files again, you use the AO constructor:
54 </p>
55 <div class="fragment"><pre>
56 a1 = ao(<span class="string">'foo.xml'</span>);
57 a2 = ao(<span class="string">'foo.mat'</span>);
58 </pre></div>
59 <p>
60 That's all there is to it.
61 </p>
62 <p>
63 To load files on the workbench, you use the relevant constructor block. For example, to load
64 an AO XML file from disk, use the <tt>ao</tt> constructor with the parameter set "From XML File"
65 (or "From MAT File" to load from a MAT file). This parameter set has one default parameter: <tt>FILENAME</tt>.
66 If you double click the cell corresponding to the parameter value you will be presented with a 'load file' dialog
67 from which you can choose the file to load.
68 </p>
69 <p>
70 To save files from within the workbench, use the <tt>save</tt> block. The parameter list and key is the same.
71 The only difference will be you will be presented with a 'save file' dialog box when editing the parameter value.
72 </p>
73 <p>
74 The following pipeline shows the load and save in action:
