The Toolbox forecasts the volatility of a (mxn) vector of data and from a variety of in-built / non-in-built GARCH models with various distributions, as well as the univariate RiskMetrics. The toolbox also estimates a number of Volatility Forecast Loss Functions and if selected Value-at-Risk for... Platforms: Matlab

It is example from physics teacher toolbox. It can show body trajectory in real time, accelerated or time step fixed. It is possible to add air friction and wind. All parameters are adjustable. Window is elastic. So it is possible to stretch the window to all screen. Font size will increase... Platforms: Matlab

Five scripts that demonstrate some aspects of the dynamics of rotating reference frames:1) rotation.m shows a very simple 3-d trajectory from inertial and rotating reference frames.2) Coriolis.m simulates a 2-d trajectory in a rotating frame that omits the centrifugal force. This allows several... Platforms: Matlab

The purpose of this file is to provide beginners a way to understand and analyse time varying coefficient values within regression analysis particularly with financial data analysis.The file is easily customisable to suit requirements and contains information describing the code for ease.I am new...

http://simulations.narod.ru/There are 400 balls in 2d that has finite size and can pass trough each other with friction. At distances more than size they have gravitation forces. Initially system rotated slightly as global. Code well vectorized, bsxfun used.The result of simulation is here:It is... Platforms: Matlab

SimMechanics is used to simulate a pendulum at the tip of a rotating arm, called a furuta pendulum. The equation of motion are then simulated by ode45 to show they are the same. All nonlinear dynamics are simulated (only one on file exchange I've seen that does that), so the equations can be used... Platforms: Matlab
