a Comparison of the numerical and analytical solutions of the fractional diffusion equation at α = 1.5, D = 0.5, obtained at instances of t = 2 (dots), t = 3 (circles) and t = 4 (crosses). The thick lines represent the analytical solutions. b Convergence of the fractional Fourier method at instances of α at final time t = 1
