Octave Tutorial

Octave Tutorial

GNU Octave is a high-level interpreted Scientific Programming Language, primarily intended for numerical and scientific computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. Octave is much similar to MATLAB.

 

 

Octave can be used through its interactive command-line interface. We can also write non-interactive programs and scripts. Most Octave programs are easily portable.

Octave provides extensive graphics capabilities for data visualization and manipulations. It has a powerful mathematics-oriented syntax with built-in 2D/3D plotting and visualization tools.

Octave 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, etc.

Install Octave

Octave is made available under the GNU General Public License. It may be freely copied and used.

Octave is cross-platform and runs under most Unix/Linux operating systems, Microsoft Windows, etc.
