Which Matlab native classes are sealed?
<p>The <code>Sealed</code> attribute when applied to a Matlab class prevents it from being subclasses, per <a href="http://au.mathworks.com/help/matlab/matlab_oop/class-attributes.html" rel="nofollow">http://au.mathworks.com/help/matlab/matlab_oop/class-attributes.html</a></p>

<p>I am interested to find out which of the native Matlab classes (in R2015b) are sealed.</p>
