To install a package from downloaded file,

or to install it directly from octave forge site

Installed packages are not ready to be used until loading them. To add a specific package to the path,
octave> pkg load PKGNAME
After loading, users can run all the functions provided by that package. To load all packages,
octave> pkg load all
To see which packages are installed,
octave> pkg list
To uninstall package,
octave> pkg uninstall PKGNAME
To update package,
octave> pkg update
To unload a specific package,
octave> pkg unload PKGNAME
The directory where octave packages are installed can be designated while configuring octave installation. The command below will install octave in subdirectories below PATH.
# ./configure --prefix=PATH
And packages are installed in OCTAVEPATH/share/octave/packages/. The default value of OCTAVEPATH is /usr/local/. You can check its directory even after installation either using
octave> OCTAVE_HOME
ans = /usr/local
or using
octave> octave_config_info('prefix')
ans = /usr/local
The command octave_config_info can give you more detailed configure information.
To check the package directory,
octave> pkg prefix
If you want to install a package in a different directory, set it before installation
Installation prefix: OCTAVEPATH/share/octave/packages
Architecture dependent prefix: OCTAVEPATH/lib/octave/packages
octave> pkg prefix NEW_LOCAL_DIRECTORY
The specific directory of a named package can also be found using
octave> pkg list PKGNAME
