Hybrid CAS and Block Pulse Functions for Numerical Solution of Fractional Population Growth Model 1

In the present paper, a computational technique is proposed to solve the population growth model (PGM). For this purpose, the operational matrix of fractional integral (OMFI) was used for cosine and sine wavelets (CASWs). One of the advantages of the proposed method is that we can turn such problems into a solution a system of algebraic equations, which is simple to solve. Finally, numerical solution of presented model and a comparison with two other methods are presented to show the validity and efficiency of the technique, and also error analysis is provided for this procedure.
