Yes, I suspect that it is a memory issue. I am working with 4GB of memory and a 2GHz Intel Core 2 Duo processor.

Yes, when i set n to 50 and Deltat to 10^6 'particleintensity' is the slowest bit. However, this is not the case when n is set to 5 and Deltat is 10^6. I need a way to only calculate particle intensity for particles that are close to the origin.

comment Fluorescence Correlation Spectroscopy Simulation
This has been working great. However, I have found that I need Deltat to be at least 1000000 and n to be at least 50. Using these parameters, the calculation of particle intensity still takes a considerable amount of time. Realistically, I only need to calculate the particle intensity when particles are close to the origin, say within a distance of Omegaz or Omegar. If I could only calculate particle intensity when particles are close to the origin, I think that would seriously reduce my calculation time. Any thoughts?

That's even better! Thanks.

@ruebenko No, I haven't attempted to compile it. My programming skills are still rather basic. I'm not quite sure how to use Compile yet.

@drN In a sense, yes this is molecular dynamics. Once I have an total intensity profile I can autocorrelate it and extract information such as concentration and diffusion coefficients among many other things.

This is about 50% faster for me too. Thanks.

@J.M. It is actually about 10% slower for me.
