摘要: Abstract In this paper, numerical solution of the Burgers’ equation is presented based on cubic B-spline quasi-interpolation. At first quasi-interpolation introduced. Moreover, scheme presented, by using derivative to approximate spatial dependent variable and a low order forward difference time variable. The accuracy proposed method demonstrated some test problems. results are found in good agreement with exact solutions. advantage resulting that algorithm very simple, so it easy implement.
