Abstract: The Legendre wavelets defined by the shifted Legendre polynomial is used to solve the numerical solution of the system of fractional differential equations with variable coefficient.The convergence analysis is presented to show that this method is correct for solving the fractional differential equations. Finally, three numerical examples are given to demonstrate the feasibility and efficiency of this method
