We first construct Haar wavelet and then derive the operational matrix of fractional integration. The operational matrix of fractional integration is utilized to reduce the system of fractional differential equations to a system of algebraic equations. Thus, we get required numerical solutions by solving corresponding system of algebraic equations. In addition, an example is presented to demonstrate the efficiency and accuracy of the proposed method.
