Details:

The following describes an issue related to path
<http://www.mathworks.com/help/matlab/search-path.html>, packages
<http://www.mathworks.com/help/matlab/matlab_oop/scoping-classes-with-packages.html#brfynt_-3>
and classes
<http://www.mathworks.com/help/matlab/matlab_oop/organizing-classes-in-folders.html#br5wlnh>,
and private functions
<http://www.mathworks.com/help/matlab/matlab_prog/private-functions.html>:


./testdir/+foo/
./testdir/+foo/bar.m
./testdir/+foo/private/baz.m


where "bar.m" is a function that calls a private function "baz.m".


function x = bar()
    x = baz();
end


and


function x = baz()
    x = pi;
end


In Octave the following fails (while it works fine in MATLAB):


>> addpath('C:\testdir')
>> foo.bar()
error: 'baz' undefined near line 2 column 9
error: called from
    bar at line 2 column 7


I had to explicitly add the private folder to the path for it to work:


>> addpath('C:\testdir\+foo\private')
>> foo.bar
ans =  3.1416


----

Similarly, private functions inside @-class folders:


./testdir/@MyClass/
./testdir/@MyClass/MyClass.m
./testdir/@MyClass/private/myfunc.m


Trying to call "myfun.m" from class methods will generate a similar 'undefined
function' error... 

----

This was initially reported in #45410, but I'm creating a separate bug report
for it.
