hi all:
i have some insects/particles that i placed in the center of an arena, and tracked their position after a set period of time. what i can get in MATLAB is a 2d scatter plot (several hundred x,y points). i have several different types of particles that show a larger or smaller degree of spread from the center, and have collected their endpoints (i don't have individual trajectories).
can i do something more interesting to communicate just 'how scattered' these particles are after time t? any good tutorials on this given my data (time 1, distance 0; time 2, distance X)? i think i might not be looking for a "diffusion coefficient", since I'm looking at single particles and not concentrations.
i think i might be looking to understand something called a "correlation time".
Thanks for any ideas
