I've written a code for solving diffusion. Now I want to check it by Gaussian distribution as initial condition. Unfortunately I don't know the exact solution for diffusion of Gaussian distribution. does anyone know?

You are probably looking for a Green's function solution: http://en.wikipedia.org/wiki/Heat_eq...olutions_in_1D
