This is a list of frequently asked questions (FAQ) for GNU Octave users. Feel free to edit this page with your changes. If you have general questions about GNU Octave, or need help for something that is not covered by the Octave manual or the FAQ, please use the help@octave. Before posting a question to the help@octave. By default, the line editing commands are similar to the cursor movement commands used by GNU Emacs, and a vi- style line editing interface is also available. At the end of each session, the command history is saved, so that commands entered during previous sessions are not lost. Access to the complete text of the manual is available via the doc command at the GNU Octave prompt. 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). It seems that universities use it for research and teaching, companies of all sizes, for development, individuals. This question comes often on Octave mailing lists, see Who Uses Octave? Rawlings and John W. Eaton at the University of Texas. Eaton was the original author of Octave, starting full- time development in February 1. He is still the primary maintainer. The community of users/developers has in addition contributed some code and fuels the discussion on the mailing lists help@octave. Like Windows 7 was to Windows XP (See our previous post on the differences between Windows XP and 7), Windows 8 is supposedly a “completely re-imagined” version. It's 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 . We hope that GNU Octave will help perform computations with the same ease as Dr. 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 GNU's infrastructure (e. Additionally, Octave receives sponsorship from the FSF's Working Together fund. However, Octave is not and has never been developed by the FSF. It is recommended to use the stable version of octave for general use, and the development version if you want the latest features and are willing to tolerate instability. The file Change. Log in the source distribution contains a more detailed record of changes made since the last release. Binary distributions exist at least for Debian, SUSE, Fedora and Red. Hat Linuxes (Intel and AMD CPUs, at least), for Mac OS X and Windows' 9. XP, Vista, and 7. If possible, the Fortran subroutines are compiled with the system's Fortran compiler, and called directly from the C++ functions. If that's not possible, you can still compile Octave if you have the free Fortran to C translator f. Eaton and others. Eaton, David Bateman, S\oren Hauberg, and Rik Wehbring. The other. is giving details on the system used so that experiments can be replicated. Send us patches if you can. We like patches. If you can't, some developers may be convinced to work on your specific problem for some money. Participate in the help. Many people who now contribute to Octave first spent. A good way to learn Octave is to understand the problems other. Octave as a whole, but it also prepares you to be a better Octave. These are. also important tasks. The documentation is easy to patch, and the help text. Editing this wiki is even easier. Find and report. bugs, making an attempt to. Eventually, you will also know how to fix them. If you want. to help with bug reports or patches, subscribe to. See. also the list of short projects. In other words, the MEX file must use the MEX interface only, and not also call on other Octave internals. It should be possible in principle to use the MEX file with other programs that implement the MEX interface (e. Matlab). The MEX file should 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 that you might effectively create a single work; this is just one example. A program that embeds the Octave interpreter (e. 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. Will you change the license of the Octave libraries for me? 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 so that 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. It's released under a BSD license! While the BSD licenses does allow one to use such code in Octave, it also allows others to further impose restrictions which Mathworks does through the MATLAB Central Terms of Use of their site. Content submitted to File Exchange may only be used with Math. Works products. It should suffice - - although interpretations of this vary - - to contact the author directly and have them send you the code personally, or download the code from the author's own website, if available. Some examples of letters/email sent to authors can be found in the page Asking for package to be released under GPL: examples. Release of official windows binaries. Experimental support for classdef. Open. GL graphics with Qt widgets. Several functions for reading, writing, and recording of audio. What's new in version series 3. X of Octave. Open. GL graphics with fltk widgets. Support for nested functions. Support for java packages in Octave core. Reading and writing of image files vastly extended. What's new in version series 3. X of Octave. Broadcasting enabled for all built- in binary element- wise operators. Performance of all m- file string functions has been improved. What's new in version series 3. X of Octave. It is available on the web at http: //www. Good starting points are the Octave Wiki http: //wiki. Octave- Forge http: //octave. We also have an IRC chat room, #octave in Freenode. How do I know, and who should I tell?”. First, see the section on bugs and bug reports in the Octave manual. When you report a bug, make sure to describe the type of computer you are using, the version of the operating system it is running, and the version of Octave that you are using. Also provide enough code and configuration details of your operating system so that the Octave maintainers can duplicate your bug. It should be possible to make Octave work on other systems as well. If you are interested in porting Octave to other systems, please contact the maintainers' mailing list. What is this Octave app in the Google Play store? Please see Android for more information. This is a sad turn of events. Once installed, Octave requires approximately 3. MB of disk space (again, considerably less if you don't compile with debugging symbols, approximately 5. MB). You will also need GCC 4. GCC 4. 4 or later is recommended. Octave's Makefiles use features of GNU Make that are not present in other versions of make. GNU Make is very portable and easy to install. Octave is intended to be portable to any standard conforming compiler. If you have difficulties that you think are bugs, please report them to the http: //bugs. For example, you may type. See the previous example. The major advantage of this is that as # is also a comment character for unix script files, any file that starts with a string like #! See the previous example. Also, double- quoted strings include backslash interpretation (like C++, C, and Perl) while single quoted are uninterpreted (like Matlab and Perl). See the previous example. As with Matlab, the end (or endfunction) keyword that marks the end of a function defined in a . Octave includes the C- like increment and decrement operators ++ and - - in both their prefix and postfix forms, in addition to +=, - =, *=, /=, ^=.+=.- =.*=, ./= and .^=. This would add one to x and then return the new value of x as the result of the expression. It is exactly the same as the expression x = x + 1. This adds one to the variable x, but returns the value that x had prior to incrementing it. For example, if x is equal to 2, the result of the expression x++ is 2, and the new value of x is 3. The general form of an unwind. The statements in cleanup are guaranteed to be executed regardless of how control exits body. Octave also has on. Cleanup since version 3. These functions are built in to the interpreter. The effect on the online documentation is relatively small, but makes the help string of functions conform to the help of Octave’s own functions. However, the effect on the appearance of printed or online documentation will be greatly improved. Tests are put after function definition in specially commented block. For example to run demo for function multinom of package specfun, use. Powerfull assert. Sections Techniques Used for Linear Algebra and Linear Algebra on Sparse Matrices from the manual describe this procedure. If you want to execute a function defined in a file, just call the function like any other Octave function: foo(arg. To execute a script from within Octave, just type its name without the . Thus, if you have a script called foo. Octave to execute it. You have to make sure that the script is in your current path. Type path in Octave to see what this path is, and type pwd to print the working directory (where you're currently standing). The current working directory is referred to as .
