In this paper,we introduced a numerical approach for solving the fractional differential equations with a type of variable-order Hilfer-Prabhakar derivative of orderμ(t)andν(t).The proposed method is based on the Jacobi wavelet collocation method.According to this method,an operational matrix is constructed.We use this operational matrix of the fractional derivative of variable-order to reduce the solution of the linear fractional equations to the system of algebraic equations.Theoretical considerations are discussed.Finally,some numerical examples are presented to demonstrate the accuracy of the proposed method. 展开更多

In this paper,we introduce a method based on operational matrix of fractional order integration for the numerical solution of fractional Mathieu equation and then apply it in a number of cases.For this,we use the block-pulse wavelets matrix of fractional order integration with respect to the Caputo sense.The method was tested by some numerical examples and changes occurred in the coefficients as well as in the derivative of the equation.Results prove the accuracy and computational efficiency of the proposed algorithm.©2019 Shanghai Jiaotong University.Published by Elsevier B.V. 展开更多
