Convergence of the solution of the fractional diffusion equation with α = 0.3 using the Prony-based method Eq. (12) with refinement in time and (A) Δ x = 1/2500, (B) 1/1250 and (C) 1/625 versus using the method of Birk and Song [54] with refinement in time and (D)Δx, = 1/2500, (E) 1/1250 and (F) 1/625.
