FAQ Octave. This is a list of frequently asked questions FAQ for GNU Octave users. We are always looking for new questions with answers, better answers, or both. Feel free to edit this page with your changes. Where do I get additional helpeditIf you cant find an answer to your question in this FAQ, wiki, or in the manual PDF you can. GeneraleditWhat is OctaveeditGNU Octave is a high level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. GNU Octave is normally used through its interactive interface CLI and GUI, but it can also be used to write non interactive programs. The GNU Octave language is quite similar to Matlab so that most programs are easily portable. The GNU Octave distribution includes a 1. Texinfo manual. Access to the complete text of the manual is available via the doc command at the GNU Octave prompt. What is Octave ForgeeditOctave Forge is a collection of packages for GNU Octave, something similar to the Matlab toolboxes. When talking about the two projects at the same time, GNU Octave is usually referred to as Octave core or just core. Octave Forge also serves as a test bed for code that may eventually end up in the core, and distributes binaries for systems with a lack of developers tools mainly Windows. Who uses OctaveeditLots of people. Universities use it for research and teaching, companies of all sizes for development, and individuals for whatever private purpose. See Who Uses Octave Who develops OctaveeditDiscussions about writing the software that would eventually become Octave started in about 1. James B. Rawlings and John W. Eaton at the University of Texas. John W. Eaton is the original author of Octave, starting full time development in February 1. Drag Racer V3 Full Game. He is still the primary maintainer. The community of users and developers has in addition contributed some code and fuels the discussion on the mailing lists helpoctave. Why OctaveeditOctaves name has nothing to do with music. It is named after Octave Levenspiel, a former professor of John who was famous for his ability to do quick back of the envelope calculations. You can hear John pronounce the name Octave a few times in this video. We hope that GNU Octave will help perform computations with the same ease as Dr. Levenspiel. Why GNU OctaveeditThe GNU Project was launched in 1.

Octave became GNU Octave in 1. This meant agreeing to consider Octave a part of the GNU Project and support the efforts of the FSF. A big part of this effort is to adhere to the GNU coding standards and to benefit from GNUs infrastructure e. Additionally, Octave receives sponsorship from the FSFs Working Together fund. However, Octave is not and has never been developed by the FSF. How can I cite OctaveeditOctave is free software and does not legally bind you to cite it. However, we have invested a lot of time and effort in creating GNU Octave, and we would appreciate if you would cite if you used. To cite GNU Octave in publications use. John W. Eaton, David Bateman, Sren Hauberg, Rik Wehbring 2. GNU Octave version 4. URL https www. A Bib. Te. X entry for La. Te. X users is. title GNU Octave version 4. John W. Eaton and David Bateman and Soren Hauberg and Rik Wehbring. Run citation at the Octave prompt for details on how to best cite the Octave version you are running. Certain Octave packages also have recommended citations in which case use citation packagename. Note that there are two reasons for citing the software used. One is giving recognition to the work done by others which we already addressed. The other is giving details on the system used so that experiments can be replicated. For this, you should cite the version of Octave and all packages used you can get this information using the ver command, as well as any details of your setup as part of your Methods. In addition, you should make your source available. See How to cite and describe software for more details and an in depth discussion. What documentation exists for OctaveeditBesides this wiki, the GNU Octave distribution includes a 1. Texinfo manual PDF. Access to the complete text of the manual is available via the doc command at the GNU Octave prompt. If you have problems using this manual, or find that some topic is not adequately explained, indexed, or cross referenced, please report it on http bugs. How can I report a bug in OctaveeditPlease read our website http www. Licensing issueseditIf I write code using Octave do I have to release it under the GPLeditThe answer depends on precisely how the code is written and how it works. Code written entirely in the scripting language of Octave interpreted code in. Code written using Octaves native code interface also known as a. Octave internals and is considered a derivative work of Octave. Therefore it must be released under terms that are compatible with the GPL. The MEX file may not use any bindings that are specific to Octave, it has to use the MEX interface only. In other words, it should be possible in principle to use the MEX file with other programs that implement the MEX interface e. Matlab. For example including an Octave header file or calling an Octave function within the MEX file, that is not related with Octaves implementation of the MEX interface make the MEX file a derivative work of Octave and has therefore to be released under terms that are compatible with the GPL. The MEX file may not be distributed together with Octave in such a way that they effectively create a single work. For example, you should not distribute the MEX file and Octave together in a single package such that Octave automatically loads and runs the MEX file when it starts up. There are other possible ways to effectively create a single work this is just one example. Code that embeds the Octave interpreter e. Octaves libraries e. Octave and therefore must be released under terms that are compatible with the GPL. Will you change the license of the Octave libraries for meeditNo. Instead of asking us to change the licensing terms for Octave, we recommend that you release your program under terms that are compatible with the GPL. This way the free software community can benefit from your work the same as you have benefited from the work of all the people who have contributed to Octave. Should I favor the MEX interface to avoid the GPLeditNo. The original reason for implementing the MEX interface for Octave was to allow Octave to run free software that uses MEX files the particular goal was to run sundials. TB in Octave. The intent was to liberate that software from Matlab and increase the amount of free software available to Octave users, not to enable people to write proprietary code for Octave. For the good of the community, we strongly encourage users of Octave to release the code they write for Octave under terms that are compatible with the GPL.
