A note on fractional diffusion equations

In the present paper, the solutions of the fractional diffusion equation of order α(0<α⩽1)α(0<α⩽1) with the initial condition xn,nxn,n is a positive integer are obtained with the help of a powerful method, i.e., the variational iteration method. The method performs extremely well in terms of efficiency and simplicity. Numerical results are presented graphically.
