Well, from the description of Particle Swarm Optimization http://en.wikipedia.org/wiki/Particle_swarm_optimization, it appears that you need to have a function that you want to optimize. There's not just one formula that applies to all PSO situations. Have you checked the File Exchange?

Then I guess you either need to hire a consultant to write it for you, or write it yourself.
