A high-level interpreted language, primarily intended for numerical computations


GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language.

Octave has extensive tools for solving common numerical linear algebra problems, finding the roots of nonlinear equations, integrating ordinary functions, manipulating polynomials, and integrating ordinary differential and differential-algebraic equations. It is easily extensible and customizable via user-defined functions written in Octave’s own language, or using dynamically loaded modules written in C++, C, Fortran, or other languages.

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

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.
  • Visualize data with high-level plot commands in 2D and 3D.
