Thanks!
I managed to isolate the issue. On both machines, when I connect with ssh
with no X forwarding then I get the error
Error: Environment variable EDITOR is not set.
Error using edit (line 61)
"Unknown service"
However, if I connect with X forwarding then everything is ok (editing /
debugging works).
Since I would like to use tmux, and keep the session alive even when I
disconnect from the ssh, then I cannot use X forwarding, because otherwise,
matlab will crash.
So anyone has any idea why I get "Error: Environment variable EDITOR is not
set." when I don't use X fwding? and how to fix it?
Many Thanks!
Yuval
PS: that's my .emacs file contents:
