Details:

= SUMMARY =

Octave treats relative paths added with addpath as relative to the current
directory. This used to be MatLab's behavior until it was changed around 2016,
see:

https://www.mathworks.com/help/matlab/release-notes.html?rntext=&startrelease=R2016b&endrelease=R2016b&category=Language+and+Programming&groupby=release&sortby=descending&searchHighlight=

= EXAMPLE =

The scripts below illustrate the changing behavior between MatLab versions:

$ mkdir -p x/foo y/foo
$ printf "function bar\ndisp('x')\n" > x/foo/bar.m
$ printf "function bar\ndisp('y')\n" > y/foo/bar.m
$ /usr/local/MATLAB/R2010b/bin/matlab -nodisplay -nosplash

                                                                              
               < M A T L A B (R) >
