Results for 1 d experiment. Simulation (dots) versus theoretical (plain line) distribution of particles that undergo non-homogeneous diffusion. The diffusion profile is a simple inverse gaussian function (in inset) with equation: D\left(x\right)=1-0.9\text{exp}(-\frac{x^2}{{\sigma }^2}) and σ = 0.1 (theoretical:plain line, simulations: triangles).
