<h4 class="subsection">11.9.2 Subfunctions</h4>
<p>A function file may contain secondary functions called
<em>subfunctions</em>. These secondary functions are only visible to the
other functions in the same function file. For example, a file
<samp>f.m</samp> containing
</p>
<div class="example">
<pre class="example">function f ()
printf ("in f, calling g\n");
g ()
endfunction
function g ()
printf ("in g, calling h\n");
h ()
endfunction
function h ()
printf ("in h\n")
endfunction
</pre></div>
<p>defines a main function <code>f</code> and two subfunctions. The
subfunctions <code>g</code> and <code>h</code> may only be called from the main
function <code>f</code> or from the other subfunctions, but not from outside
the file <samp>f.m</samp>.
