Octave 3.6.4 on Ubuntu 12.04

Here’s how to install GNU Octave 3.6.4 on Ubuntu 12.04 (also on Ubuntu 10.04):

Open Terminal and do:
1) sudo apt-add-repository ppa:octave/stable
2) sudo apt-get update
3) sudo apt-get install octave
4) sudo apt-get install liboctave-dev

Note: if you have Octave 3.2 installed already, these commands will uninstall Octave 3.2 and install Octave 3.6 on Ubuntu 12.04.

To install packages, start Octave in sudo mode i.e. type in Terminal:
sudo octave
and then you can install packages by typing in Octave:
pkg -verbose install -forge specfun
to install the specfun package, and so on.
DON’T FORGET to exit Octave after done installing packages (so that you’re not left running Octave in sudo privileges).

To use the Octave packages you must type pkg load image to load the “image” package and so on.

You can list the loaded packages by typing in octave pkg list. The loaded packages have an asterisk next to their name.

  2. Fantastic, thanks!

    Note to others: make sure to install both the “octave” and the “liboctave-dev” packages, otherwise I got.

  4. Hi, I have ubuntu 12.04 LTS 64 bit installed in lenovo thinkpad E430
    I foolwed the same rule but this is the problem:

    somenath@thinkpad~$sudo apt-get install octave
    Reading package lists… Done
    Building dependency tree
    Reading state information… Done
    Some packages could not be installed. This may mean that you have
    requested an impossible situation or if you are using the unstable
    distribution that some required packages have not yet been created
    or been moved out of Incoming.
    The following information may help to resolve the situation:

    The following packages have unmet dependencies:
    octave : Depends: libarpack2 (>= 2.1) but it is not going to be installed
    E: Unable to correct problems, you have held broken packages.

  5. Thank you very much. Your instructions worked perfectly.
    However, I can only start Octave by typing “octave” at the shell prompt. Clicking on the the Octave Icon, does work. .

  7. from the article: “To use the Octave packages you must type pkg load image to load the “image” package and so on.” it is easier to add the option -auto to pkg install, this way octave will load the packages automatically after restarting.

  8. Thanks. It works very nice. Can you please suggest the way to install the octave.info for 3.6.4 version?
    Thanks.
