Octave should be able to parse the events section of a classdef definition but nothing is done with it.  Progress on this feature is tracked in bug report {{bug|56194}}.

==== built-in class as superclass ====
=== Open Bug Reports for Other Issues ===
 
Octave does not allow subclassing built-in classes.  In Matlab, classdef objects may subclass built-in integer, floating point, and logical types.  For example,
<source lang="octave">
classdef nonsense < uint32
  ...
end
</source>
 
does not work.
 
Progress on this feature is tracked in bug report {{bug|44035}}.
 
==== concatenation of classdef objects ====
 
Octave does not support concatenation of classdef objects to create classdef array objects.
 
Example:
 
<source lang="octave">
classdef MyClass < handle
end
 
c = MyClass();
cc = [c, c];  % won't work
</source>
 
For now you can use a cell-array of objects instead:
<source lang="octave">
cc = {c, c};  % ok
</source>
 
Progress on this feature is tracked in bug reports {{bug|44665}} and {{bug|53906}}.
 
==== Saving and loading classdef objects ====
 
Saving and loading classdef objects is not supported.
 
Progress on this feature is tracked in bug report {{bug|45833}}
 
=== Open Bug Reports for Issues not Described Above ===
