Software

GNU Octave

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.

ALS

An Octave package for determining noise covariances from routine operating data, written for Octave. Also works with Matlab.

MPC Tools

An Octave package for control and estimation tool for linear and nonlinear dynamic models.
