In this paper, a new numerical method for solving time-fractional diffusion equations is introduced. For this
purpose, finite difference scheme for discretization in time and Chebyshev collocation method is applied. Also, to
simplify application of the method, the matrix form of the suggested method is obtained. Illustrative examples
show that the proposed method is very efficient and accurate.
