bm_particle_intensity: Simulate 2D particle trajectory follows Brownian Motion

Description

Simulate 2D particle trajectory follows Brownian Motion (BM) for M particles.

Usage

Value

Position matrix with dimension M\(\times\)len_t

by 2 for particle trajectory. The first M rows being the initial position pos0.

Arguments

pos0

initial position for M particles, matrix with dimension M by 2

M

number of particles

len_t

number of time steps

sigma

distance moved per time step
