This paper presents numerical methods for solving the one-dimensional fractional reaction-
-diffusion equation with the fractional Caputo derivative. The proposed methods are based
on transformation of the fractional differential equation to an equivalent form of a integro-
-differential equation. The paper proposes an improvement of the existing implicit method,
and a new explicit method. Stability and convergence tests of the methods were also con-
ducted.
