Nonlinear systems with attractors


Updated 18 Dec 2017

View License

This is a collection of Simulink blocks implementing simple nonlinear dynamical systems that have attractors in their state space.
A general 3D Simulink scope (coded in the s-functions sfun3d.m) is used to display (in 3D) the evolution of the system during the simulation.

Currently (Jan 2017), the featured systems are Lorenz, Van Der Pol, simple Lotka-Volterra, competitive N-D Lotka Volterra and Henon. Note that this only works for versions 2014b and later.

Version Published Release Notes

Updated the 3DScope block and its s-function to the latest (and probably last ever) and greatest.

Fixed minor issues.

Updated the 3D scope function, since the older one did not work anymore for later MATLAB versions. The new one (also available in the "3DScope" File Exchange contribution) is more capable, faster, simpler and corrects several issues.

Added several types of Lotka-Volterra systems.
