Perfect. This works for me now.

Closing as fixed.

This is still the same with Octave 6.0.90.

Hmm, I just assumed that those were classdef .m files.  So instead, what happens when we really do have a classdef .m file?  If there is something simple like

classdef myclass

in a file called myclass.m in the path, what does "which myclass" report?

Running online, I get

inputParser is a built-in method  % inputParser constructor

containers.Map says the same thing.

What does Matlab display for

which inputParser


Does it just show the path to the .m file (I assume there is one) or does it also print a message like Octave does with something like "inputParser is the classdef file found in:..."?

+1 I saw this problem as well.

Also of note:

>> which inputParser
'inputParser' is a built-in function

>> __which__ inputParser
ans =

  scalar structure containing the fields:

    name = inputParser
    file =
    type = built-in function

>> file_in_loadpath inputParser.m
ans = C:\Octave\4.2.0\share\octave\4.2.0\m\general\inputParser.m

This probably hints at somethin deeper, but which() returns the wrong answer for a classdef file like inputParser.

octave:1> which inputParser
'inputParser' is a built-in function
