To install odepkg, from octave prompt, execute:
>> pkg install -forge odepkg

Confirm install by:
>> pkg list

To active the package:
>> pkg load odepkg

The package to be auto loaded at octave start-up:
>> pkg rebuild -auto odepkg
Then restart octave and confirm by:
>> pkg list
(Activated package are marked by '*').
