In mathematics, moduli of smoothness are used to quantitatively measure smoothness of functions. Moduli of smoothness generalise modulus of continuity and are used in approximation theory and numerical analysis to estimate errors of approximation by polynomials and splines. ==Moduli of smoothness== The modulus of smoothness of order 〔DeVore, Ronald A., Lorentz, George G., Constructive approximation, Springer-Verlag, 1993.〕 of a function is the function and : where we the finite difference (''n''-th order forward difference) are defined as : 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Modulus of smoothness」の詳細全文を読む スポンサード リンク
