	<p>
  Up to now, all the activity of the tutorial has been carried out on the MATLAB
  command terminal. It is, of course, much more convenient to collect the commands
  together in to a MATLAB script. In this sense, LTPDA scripting is just the same
  as normal MATLAB scripting; just using LTPDA commands.
</p>
  Here's an example script which makes two white-noise time-series and estimated the 
  power-spectral-density of each.
</p>
<div class="fragment"><pre>
<span class="comment">%% Make two test AOs</span>

a1 = ao(plist(<span class="string">'tsfcn'</span>, <span class="string">'randn(size(t))'</span>, <span class="string">'fs'</span>, 10, <span class="string">'nsecs'</span>, 100));
a2 = ao(plist(<span class="string">'tsfcn'</span>, <span class="string">'randn(size(t))'</span>, <span class="string">'fs'</span>, 10, <span class="string">'nsecs'</span>, 100));

<span class="comment">%% Make TFE</span>

psds = psd(a1, a1);
a1xx = psds(1);
a2xx = psds(2);

<span class="comment">% The following works!.</span>
b1xx = psd(a1); 
b2xx = psd(a2); 

</pre></div>
<p>
  You can explore the commands used to rebuild the object by using the <tt>type</tt>
  method. Or you can plot the history as we did earlier. For example, try this command 
  for each of the cases above:
</p>
<div class="fragment"><pre>
  type(a1xx)
  type(b1xx)
</pre></div>
