<h4 class="subsection">11.7.2 Subfunctions</h4>
<p>A function file may contain secondary functions called
<dfn>subfunctions</dfn>. These secondary functions are only visible to the
other functions in the same function file. For example, a file
<samp><span class="file">f.m</span></samp> containing
<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>
<p class="noindent">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><span class="file">f.m</span></samp>.
