Design of an operational matrix method based on Haar wavelets and evolutionary algorithm for time-fractional advection–diffusion equations

open access: yesOpen Engineering
In this study, we introduce an operational matrix (OM) method based on Haar wavelets (HWs) to approximate the solution of time-fractional advection–diffusion equations (TFADEs). These problems involve fractional derivatives in the Atangana–Baleanu Caputo
