I have added a MATLAB version of some of the programs on the Egwald website:

1. Optimal Control: The Rocket Car: http://www.egwald.ca/optimalcontrol/rocketcar.php

2. Nonlinear Dynamics: Limit Cycles: Kaldor Business Cycle Model: http://www.egwald.ca/nonlineardynamics/limitcycles.php

3. Astronomy: Stellar Collapse: http://www.egwald.ca/astronomy/stellarcollapse.php

I will add some more MATLAB programs in the future.

Rocket Car: Example of Optimal Control Theory, extremal controls, fun with mathematics; the bang-bang principle

http://www.egwald.ca/wiens/governmententerprises.php GOVERNMENT ENTERPRISE:
THE NEXUS OF SOCIALISM AND CAPITALISM
by Elmer G. Elmer Wiens

I wrote this back in 1999. Interesting how the economies / politics of China, Russia and Canada have changed since then. State Owned Enterprises are ubiquitous https://en.wikipedia.org/wiki/State-owned_enterprise Can they be managed through managerial incentives and achieve the same efficiency as privately / stock owned firms: The Public Firm with Managerial Incentives by Elmer G.
