random_walk_3d_simulation


random_walk_3d_simulation, an Octave code which simulates a random walk in a 3D region.

The code random_walk_3d_simulation() plots averaged data for any number of random walks that each use the same number of steps. The data plotted is the average and maximum of the distance squared at each time step. The average distance squared should behave like the number of time steps.

Usage:

random_walk_3d_simulation ( step_num, walk_num )
where
