Octave setup

A few notes regarding octave on Ubuntu.

I installed basic Octave-3.0.0 package and wanted to install additional packages, but run into problems. Here is the right way to do this:

• Install Octave

 sudo apt-get install octave3.0

• optionally check which octave. In my case the old version was removed leaving behind dead link from /usr/bin/octave to /etc/alternatives... I recreated the link to the latest version.

• Install the development package octave-headers - you will need this to install additional packages

 sudo apt-get install octave3.0-headers

• Download the desired packages from sourceforge:

 http://octave.sourceforge.net/packages.html

• Install (do not unzip) the octave packages from octave. Note, if you want to install them globally for all users, you need to start the octave as root:

 sudo octave
 ...
 octave:1>  pkg install /home/me/Desktop/image-1.0.6.tar.gz
 ...
 

• optionally check the packages from ortave with

 pkg list

You are done. If you want to uninstall package, consult help or just do it:

 help pkg
 pkg uninstall image

Good luck.
