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>. </body></html>
