Instructions for setup and run octave for windows with iris toolbox.

Installing GNU Octave

Download and install the latest official version of GNU Octave from the official web-site.

It's a good idea to allow creating a desktop shortcut during installation.

Other requirements

It's strongly recommended to install MikTeX, a free typesetting system used to produce PDF reports in IRIS. Please make sure that path to MikTeX directory does not contain any whitespace characters.

Installing IRIS for Octave


    1. Download the latest release of iris4octave archive and store in a temporary location on a disk.

    2. Unzip the archive into a folder on user's hard drive (preferably without whitespace characters in the pathname), e.g. C:\IRIS_Tbx. This folder is called the IRIS root.

    3. Open GNU Octave.

    4. In Octave File Browser please navigate to the IRIS root folder.

    5. Type the command “iris4octaveinstall” in Octave Command Window and press enter.

    6. If no errors were shown in the Command Window during installation process (simple warnings are fine usually) you should be able to run “irisstartup” now.

      How to start IRIS in Octave

      Don't use command “addpath” before starting IRIS up (as you might be used to in Matlab), just navigate to IRIS root using Octave File Browser before running “irisstartup” script.

      Issues when working with Octave

      • Even though GNU Octave has been actively developing to provide you with the most of Matlab's features including Graphical User Interface and compatibility with the basic operating systems like MacOS, Linux and MS Windows, you may still face some troubles working in a particular environment. Should you face any issues please feel free to report it to
      • You may also find it useful to check out the list of frequently asked questions (FAQ) for GNU Octave users. We would especially draw your attention to the speed issue which is most likely to be adressed in a newer Octave versions and a graphical adapter issue which in most cases can be adressed by updating drivers of your graphical adapter.
      • If you've had an older version of the GNU Octave installed on your machine it might happen that newly installed Octave does not start or crash when starting up. In this case you will have to remove ".config" folder from your user directory (usually, "C:\Users\<your_username>").
