Details:

Suppose I have in a directory on my Octave path, a subdirectory named @myclass
containing myclass.m with the following content:

classdef myclass < handle
end


In both, MATLAB and Octave the class works just fine. But exist('myclass')
returns 2 in MATLAB and 0 in Octave. On the other hand,
exist('@myclass/myclass') returns 2 on both.

MATLAB output:

>> obj = myclass

obj = 

  myclass with no properties.

>> exist('myclass')

ans =

     2

>> exist('@myclass/myclass')

ans =

     2


Octave output:

octave:1> obj = myclass
obj =

  myclass object with properties:


octave:2> exist('myclass')
ans = 0
octave:3> exist('@myclass/myclass')
ans = 2
