īecause Octave is made available under the GNU General Public License, it may be freely changed, copied and used. Its syntax is very similar to MATLAB, and careful programming of a script will allow it to run on both Octave and MATLAB. It is not object-oriented, but it does support various data structures.

The syntax is matrix-based and provides various functions for matrix operations. Octave programs consist of a list of function calls or a script. However, it does not support passing arguments by reference. It is a structured programming language (similar to C) and supports many common C standard library functions, and also certain UNIX system calls and functions. The Octave language is an interpreted programming language. Octave interpreter works with gnuplot and Grace software to create plots, graphs, and charts, and to save or print them.Octave is extensible using dynamically loadable modules.Octave uses an interpreter to execute the Octave scripting language.Octave is written in C++ using the Standard Template Library (STL).For example, Octave was used on a massive parallel computer at Pittsburgh supercomputing center to find vulnerability related to guessing social security numbers. In addition to use on desktops for personal scientific computing, Octave is used in academia and industry. The program is named after Octave Levenspiel, a former professor of the principal author who was known for his ability to perform quick back-of-the-envelope calculations. Version 3.0 was released on December 21, 2007. The first alpha release dates back to Januand on Februversion 1.0 was released. At first it was intended to be a companion to a chemical reactor design course. 9.2.3.1 Graphical user interfaces (GUI).9.2 Numerical packages and libraries interfacing with GNU Octave.5.1 Command and variable name completion.
