According to the MATLAB documentation it is possible to define a class without
explicitly defining a constructor. MATLAB supplies a default constructor. But
Octave classdefs currently need an explicitly defined constructor.

"If a class does not define a constructor, MATLAB supplies a default
constructor that takes no arguments and returns a scalar object whose
properties are initialized to property default values. The default constructor
supplied by MATLAB also calls all superclass constructors with no arguments or
with any argument passed to the default subclass constructor."[1]
Example of a class without an explicitly defined constructor:

classdef class_without_ctor

end
