Journal Article 2021 11 18 This paper deals with the generalization of the fractional operational matrix of Jacobi wavelets. The fractional population growth model was solved by using this operational matrix and compared with other existing methods to illustrate the applicability of the method. Then, convergence and error analysis of this procedure were studied.  Hybrid functions Jacobi polynomials Operational matrix Population growth model Wavelets https://cmde.tabrizu.ac.ir/article_14470_fddd3e53f809a025504d7aad9bd73eed.pdf
