Kui kasutad Windowsi:
Enne GNU Octave installimist loo oma (kui sinu nimi on "Jaan") 
kataloog ("octavel") GNU Octaves kirjutatud programmide salvestamiseks:
C:/Users/Jaan/octavelbr/
  GNU Octave installimis vaata: http://staff.ttu.ee/~kaspar/Mehaanika/EhMeh_abi/Octave/oct_inst_win.pdf
  http://octave.sourceforge.net/
Selleks, et GNU Octave leiaks ülesse programmid kataloogis ("octavelbr") ja programmid mälupulgalt 
(Z:/octaveProgrammid), leia installitud GNU Octave fail "octaverc":
C:\Program Files (x86)\Octave\share\octave\3.0.3\m\startup
C:\Program Files (x86)\Octave\share\octave\3.0.3\m\startup\octaverc
Kirjuta selle faili ("octaverc") lõppu järgmised read: 
   addpath (genpath ("C:/Users/Jaan/octavelbr/"));
   addpath (genpath ("file:///Z:/octaveProgrammid"));
Salvesta fail. Käivita arvuti uuesti. Käivita GNU Octave. Sisesta käsk: path
Nüüd peaks ekraanile ilmuma teed kataloogide juurde kust GNU Octave otsib faile.
Seal peab olema ka teed:
        C:/Users/Jaan/octavelbr/
        file:///Z:/octaveProgrammid

Kui kasutad Linuxit:
Loo oma kodukataloogi: /home/jaan  fail ".octaverc" ja fail "octavelbr"
 /home/jaan/.octaverc
 /home/jaan/octavelbr
Selle  faili (".octaverc") sisu on järgmine:
## System-wide startup file for Octave.
##
## This file should contain any commands that should be executed each
## time Octave starts for every user at this site.

## On a Debian GNU/Linux system, Octave also searches for local files and 
## directories below /usr/local/share/octave/site-m/.  Please see the Octave 
## documentation for other variables you might want to set here.

#addpath (genpath ("/usr/local/share/octave/site-m/"))
addpath (genpath ("/home/jaan/octavelbr/"))
addpath (genpath ("/media/E_OPE/octaveProgrammid"))

/home/jaan/octavelbr - siia saad panna oma ja allalaaditud .m failid
/media/E_OPE/octaveProgrammid - siit mälupulgalt käivitab GNU octave funktsioone
ja programme
