# GNU Octave Wiki

GNU 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. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable.

This wiki is intended to supplement the Octave documentation. Before adding content, please check that it is not already part of, or belongs in, the Octave's documentation.

## Octave FAQ

The FAQ is a list of frequently asked questions (FAQ) for Octave users and a good place to start.

Answers to questions regarding what is Octave, licensing, new features, documentation, installation, coding, contributing to Octave, and more, are found there.

## Table of contents

Below is a temporary attempt to organize the "most wanted" pages of the Wiki. A list of all pages on the wiki can be seen here. To locate something specific, try the wiki's search box, or prepend `site:http://www.octave.org/wiki/`

to a google search.

### Editors & Octave

### Plotting tutorial

All or most of the information about plotting in Octave can be found in the manual and on the internet. This information can be too scattered over different resources for a new user to find his/her way into solving a plotting problem/need. This tutorial should be considered as the 'recipe text' by examples if you consider the manual as a 'recipe ingredients only'.

- Recap of the hierarchy of each plot element
- The order of the commands matter sometimes
- Changing text elements (label, title)
- More control over subplots
- Enable "linestyle" functionality for Gnuplot's x11 terminal

### Miscellaneous

- Cookbook - Several simple and useful examples.
- Tips and tricks - Guidelines to improve your coding skills.
- Fortran - Accessing liboctave from a Fortran 2003 program.
- All Pages - A list of all special pages (like recent changes to the wiki)
- Publications using Octave - A compilation of scientific publications making reference to GNU Octave (add yours!).
- Octave fun - Coding can be fun -- miscellaneous more or less funny scripts
