This is related to bug #61521.

Suppose you have a self-contained classdef file and you ask for the help with
.m tacked on:


>> help classdef_infile.m  # <-- Note .m here, and *file* below
                               /
                              /
 'classdef_infile.m' is a file from the file
/home/cbm/src/tmp/classdef_infile.m

CLASSDEF_INFILE  A classdef living in a single m-file

   Some tests:
   >> 6 + 7
   ...


>> a = classdef_infile()
error: class not found: classdef_infile
error: called from
    classdef_infile at line 39 column 18




Restart, try again without the .m:


>> help classdef_infile
'classdef_infile' is a class constructor from the file
/home/cbm/src/tmp/classdef_infile.m

CLASSDEF_INFILE  A classdef living in a single m-file

   Some tests:
   ...
 
>> classdef_infile()
ans =
class name = "default", age = 42


## BUT we can break it again by doing .m:

>> help classdef_infile.m
'classdef_infile.m' is a file from the file
/home/cbm/src/tmp/classdef_infile.m

CLASSDEF_INFILE  A classdef living in a single m-file

   Some tests:
   ...

>> classdef_infile()
error: class not found: classdef_infile
error: called from
    classdef_infile at line 39 column 18
