Free simulation script

Order book Simulation is designed to be a very useful artificial stock market simulation including a set of classes that can be used to simulate operations of an exchange order book allowing limit and market orders.

SSTSLAB is an effective tool which provides you a simple Space Tether Simulation Laboratory. This tool is totally free.

Major Features:

1. It is a simulation tool for matlab/simulink, the current version is a beta version, it need more test work to make sure that the results are acceptable accurate.
   
2. Set the SSTSLAB folder as the current work path of MATLAB, which includes the following files: No. File Name Description
   • 1 SSTS_Contents.m Contents for SSTSLAB
   • 2 SSTS__lib_math.mdl Some math blocks for tether simulation
   • 3 SSTS__tether_dumbbell.mdl Dumbbell tether simulation
   • 4 SSTS__tether_dumbbell_replot.m Plot figures for dumbbell tether
   • 5 SSTS__tether_MMET_I.mdl MMET-I tether simulation

   • 17 SSTS__plot_orbit_position.m To plot the position function of orbits( cycles ) as follows: R(theta) =rp*(1 e)/(1 e*cos(theta))
   • 18 SSTS__plot_orbit_position3d.m To plot the position function of orbits( cycles ) as follows: R(theta) = rp*(1 e)/(1 e*cos(theta)) in 3D figure
   • 19 Jpg files To support mdl files

It records the history of each particle so it can animate and display a path of its travels. At any stage you can rotate your view in 3D and zoom in and out. Gravit uses OpenGL with Lua, SDL, SDL_ttf and SDL_image.

Major Features:

1. View the simulation in 3D using stereoscopic imaging
2. Can be installed as a screen saver in Windows
3. You can record, then play back at any speed
4. Store every particles position for every frame in memory
5. Compress history when needed, for very long recordings
6. Mouse controllable rotation
7. Console with script execution
8. Colors can be based on mass, velocity, acceleration, momentum or kinetic energy
9. See an oct-tree being created in real-time
10. Save/Load functionality
11. Update display/input while recording a frame

Requirements: Linux, Windows and Mac OS X
