Stochastic-Models
Usefull models simulating stochastic processes in different times scales with or without reproduction of long-term percistence (Hurst-Kolmogorov behaviour). Also a simple tool for determening the Hurst coefficient is provided. All code is in the form of Matlab functions.
Non-Linear-Systems
Two usefull examples of non-linear systems solved with 4th order Runge-Kutta scheme. Lorenz convection equations for flow produced by temperature gradient and non-linear forced spring-mass system described by the so called Buffing equation. The first was picked as an example of non-linear flow equations with historical importance and the second was picked because it is a closed, fully known, deterministic system. I invite you to play with the parameters, seat back and admire the chaos arise for pure determinism.
