However, the error analysis to show the convergence of the method has not been discussed. Therefore, error analysis of the approximation method is established in the Holder classes Hs[0, 1] to show the efficiency of the method. The connections of the module of difference smoothness of the function is also established. Finally, some numerical examples of the implementation the method for the functions from Holder classes are presented.en-USNumerical integration, Holder classes, liner Legendre multi-wavelets, error analysis, computational method, efficencyArticle625562591417
