Octave uses the text before the cursor as the initial portion of the name to complete. Typing a TAB character on the command line causes Octave to attempt to complete variable, function, and file names (similar to Bash's tab completion). Notable features Command and variable name completion

The program runs on Microsoft Windows and most Unix and Unix-like operating systems, including Linux, Android, and macOS. 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 supports various data structures and allows object-oriented programming. 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 although function arguments are copy-on-write to avoid unnecessary duplication. 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 includes a Graphical User Interface (GUI) in addition to the traditional Command Line Interface (CLI) see #User interfaces for details.

Alternatively, gnuplot can be used for the same purpose.

Octave interpreter has an OpenGL-based graphics engine 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 C++ standard library.

Īcceleration with OpenCL or CUDA is also possible with use of GPUs. For example, Octave was used on a massive parallel computer at Pittsburgh Supercomputing Center to find vulnerabilities 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. Version 6.4.0 was released on Oct 30, 2021. The first alpha release dates back to 4 January 1993 and on 17 February 1994 version 1.0 was released. At first it was intended to be a companion to a chemical reactor design course.

It would be better to remove the elseif condition entirely and only have else instead. While(r != 0) on line 16 - this won't run, not even once, since you define r as 0 in line 3 and don't assign a new value to it later.Įlseif(x

If, however, you call the function with the arguments, they will initialize the variables x and y correctly and your code will work. That would be similar to you having only test = gcd() in your test file.

That's why you get an "undefined variable" error.

gcd.m), when you hit "Save and run", Octave will itself call your function, but it's not clever enough and won't use any parameters in doing so. If all you have is the function definition file (i.e.

The numbers I've chosen are only an example. If the output doesn't work as expected, restarting Octave should fix it. In the same directory you have saved gcd.m, create a file (for example: gcdtest.m) and put the following code in it: test = gcd(40, 50) You have to save your code in a file called gcd.m and then create a new file so that you can call that function from it.
