GAIO

(Global Analysis of Invariant Objects) is a Matlab toolbox for the computational analysis of dynamical systems. It provides data structures and algorithms for the set-oriented computation of

• invariant sets (maximal invariant set, chain recurrent set, periodic points, global attractor) of arbitrary dimension or topology
• invariant manifolds (stable/unstable manifold of an arbitrary invariant set)
• invariant measures, almost invariant sets, coherent sets
• value functions for optimal control problems

Installation

After unpacking the archive add the resulting folder to your Matlab path, e.g.

>> addpath(genpath('/Users/gaioguy/GAIO'))
