The fractional Burgers equation is a beneficial model for describing the physical processes of unidirectional propagation of weakly nonlinear acoustic waves through a gas-filled pipe. In order to provide a numerical scheme, we consider the two-dimensional Pell polynomials and estimate the Caputo fractional derivative as well as other terms in the main equation by operational matrices. By collocating resultant approximate equations and initial-boundary conditions, a nonlinear system of equations arises, which can be solved via fsolve\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\texttt {fsolve}$$\end{document} command in MATLAB. The convergence of the numerical scheme is fully discussed. Several test problems are presented for comparing our results with other numerical methods in the literature.
