## 1 A Brief Introduction to Octave

GNU Octave is a high-level language, primarily intended for numerical computations. It is typically used for such problems as solving linear and nonlinear equations, numerical linear algebra, statistical analysis, and for performing other numerical experiments. It may also be used as a batch-oriented language for automated data processing.

Until recently GNU Octave provided a command-line interface with graphical results displayed in separate windows. The current version (version 3.8, released in late 2013) also provides, by default, a graphical user interface.
