GNU Octave
Scientific Programming Language
- Powerful mathematics-oriented syntax with built-in plotting and visualization tools
- Free software, runs on GNU/Linux, macOS, BSD, and Windows
- Drop-in compatible with many Matlab scripts
Syntax Examples
The Octave syntax is largely compatible with Matlab. The Octave interpreter can be run in GUI mode, as a console, or invoked as part of a shell script. More Octave examples can be found in the wiki.
Solve systems of equations with linear algebra operations on vectors and matrices.
b = [4; 9; 2] # Column vector
A = [ 3 4 5;
1 3 1;
3 5 9 ]
x = A \ b # Solve the system Ax = bVisualize data with high-level plot commands in 2D and 3D.
x = -10:0.1:10; # Create an evenly-spaced vector from -10..10
y = sin (x); # y is also a vector
plot (x, y);

xlabel ("x");
ylabel ("sin (x)");
Install
Executable versions of GNU Octave for GNU/Linux systems are provided by the individual distributions. Distributions known to package Octave include Debian, Ubuntu, Fedora, Gentoo, and openSUSE. These packages are created by volunteers. The delay between an Octave source release and the availability of a package for a particular GNU/Linux distribution varies.
Alternatively, many distributions support Flatpak and one can obtain GNU Octave from Flathub.
The Octave Wiki has instructions for installing Octave on macOS systems. Octave may also be available in third-party package managers such as Homebrew, MacPorts, or Fink.
Executable versions of Octave for BSD systems are provided by the individual distributions. Both FreeBSD and OpenBSD have Octave packages. These packages are created by volunteers. The delay between an Octave source release and the availability of a package for a particular GNU/Linux distribution varies. The Octave project has no control over that process.

Unless your computer has more than ~32GB of memory and you need to solve linear algebra problems with arrays containing more than ~2 billion elements, this version will offer no advantage over the recommended Windows-64 version above.- octave-5.2.0_1-w64-64-installer.exe (~ 286 MB) [signature]

Octave Forge
Octave Forge
is a central location for development of packages for GNU Octave,
similar to Matlab's toolboxes. To install a package, use the
pkg command from the Octave prompt by typing:
pkg install -forge package_name
pkg load package_nameDevelopment
