## 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.

The current version of Octave executes in a graphical user interface (GUI). The GUI hosts an Integrated Development Environment (IDE) which includes a code editor with syntax highlighting, built-in debugger, documentation browser, as well as the interpreter for the language itself. A command-line interface for Octave is also available.
