diffusion {ibm}

Brownian diffusion of a set of particles

Description

This funtions performs a brownian difussion over a set of particles. The dimension is automatically calculated from the number of columns of the object.

Usage

diffusion(object, sd, ...)

Arguments

object

The positions of the particles, dimension is taken from the number of columns or assumed to be 1 is no columns.

sd

Standard deviation for the gaussian jump, for dynamics models should be set proportional to sqrt(dt).

...

Additional arguments for different methods.

Details

This functions apply a brownian diffusion to a set of point coordinates.
