【Abstract】 This paper deals with the optimal approximation property as the cubic spline interval wavelet is used in the interpolation. The interpolation error is also discussed. A new algorithm is presented in which two one\|order differential matrixes are used to substitute for the two\|order one. The numerical solution of Burgers equation has been derived. And it is proved that the coefficient is somewhat larger.更多还原
