<p>Since version 4.0, Octave has limited support for <code class="code">classdef</code> classes.  In
contrast to the aforementioned classes, called <em class="dfn">old style classes</em> in this
section, <code class="code">classdef</code> classes can be defined within a single m-file.  Other
innovations of <code class="code">classdef</code> classes are:
</p>
<ul class="itemize mark-bullet">
<li><b class="b">access rights</b> for properties and methods,

</li><li><b class="b">static methods</b>, i.e., methods that are independent of an object, and

</li><li>the distinction between <b class="b">value and handle classes</b>.
</li></ul>

<p>Several features have to be added in future versions of Octave to be fully
compatible to <small class="sc">MATLAB</small>.  An overview of what is missing can be found at
<a class="url" href="https://wiki.octave.org/Classdef">https://wiki.octave.org/Classdef</a>.
