This would be my sugguestion.
Have the user run screen. When the job starts, do a
<ctrl>-a d
This will detach the screen.
The person can log out then come back on and type in screen -r to
reattach it.
Or do a
<ctrl>-a c
This will create two windows over the telnet session. By pressing <ctrl-a>
twice, it will toggle between screens.
I am not familiar with matlab, but if it either runs a job and puts it to
screen or writes it out to disk, (it is not interactive), you may want to
make use of the batch command.
