<blockquote><p>Register a function to be called when Octave exits. For example,
<pre class="example"> function last_words ()
disp ("Bye bye");
endfunction
atexit ("last_words");
</pre>
<p class="noindent">will print the message "Bye bye" when Octave exits.
<p>The additional argument <var>flag</var> will register or unregister
<var>fcn</var> from the list of functions to be called when Octave
exits. If <var>flag</var> is true, the function is registered, and if
<var>flag</var> is false, it is unregistered. For example,
after registering the function <code>last_words</code> above,
<pre class="example"> atexit ("last_words", false);
</pre>
<p class="noindent">will remove the function from the list and Octave will not call
<code>last_words</code> when it exits.
<p>Note that <code>atexit</code> only removes the first occurrence of a function
from the list, so if a function was placed in the list multiple
times with <code>atexit</code>, it must also be removed from the list
multiple times.
