Did you ever wonder, how they do the simulation of all that snow, rain, dust, smoke, and fire in modern computer games? How they model bullets, ropes, curtains and solar systems?
With this particle system toolbox you can easily create particles, attractions, and springs in a particle system environment with gravity and drag and graphically simulate their interactions with just a few lines of code. Run one of the 12 demos and read the detailed documentation at

@retta EL Sayed: The toolbox allows you to create particles at certain initial positions with certain initial velocities. You can define springs and attractions between the particles and have the toolbox simulate the reaction of the particles. Additionally, you have to do the collision detection with the other plane and the time measuring.
Hi Joerg, Very nice work! I am trying to release a specific number of particles from a specific plan in specific geometry and measure how long it takes to hit another plane in the same geometry. Do you have an advices about what direction I should follow?
@yousra tchorbo: If you can express your problem in terms of (additional) forces acting on the particles, you can use the method I described a few years ago:
You can write your own
method and call
Thank you for your great work !
I want to simulate a smoke generated by an explosion. How can I do that ?
The smoke follows a Gaussian Plume Equation.
@Johannes Korsawe: Right now, you can write your own
method and call
method. I save your request on my "stack of things to do ...".
That is some nice piece of code.
Could be extended to application of external forces? (or is this possible by now?)
@Sangeeta Ydaav: Press the big blue button in the upper right corner of this page to download the Particle System Toolbox.
Sir I do not have matlab particle simulation toolbox Can you send me the required files so that I can install Particle simulation toolbox?
Great work! I suggest to improve it by allowing the particles to be fixed in a desired direction (x, y, z or arbitrary).
In addition, I ported this framework in C/C++, if someone is interested please let me know.
@ Prashant Pawar: The Mathworks augmented the Matlab object model in R2008a. Therefore you have to use a version equal or higher than that for the PSTB 2.x. The error indicates that you use an older version of Matlab. I will send you a 1.0 version of the PSTB that sholud work with your Matlab via e-mail .
I am getting following error
??? Error: File: particle_system.m Line: 1 Column: 10
A class definition must be in an "@" directory.
Error in ==> demo_1 at 23
Particle_System = particle_system
Can you plz help me about avoiding the error.
It is a very long story, why I had to do that ...
The password is: dummy
So, what is the password to read the pdf documentation??
Seems silly to password protect the documentation.
John, seems like I'm a little antediluvian regarding file size. I just can't get rid of that feeling that there are still some 56k-modem users out there in Matlab Country, hating to download "large" files for just a sneak preview... ;-)
Complex, but absolutely splendid!
My only thought was a minor one. I'd have liked to see the pdf documentation already be included in the zip file itself. It is something that any user will want to read and keep around, so why make the user download it separately, then move it into the particles directory to keep it around?
