其他摘要：In this article we study the Hausdorff approximation of the Haarscaling function by sigmoidal scaling functions. We prove upper and lower estimatesfor the value of the Hausdorff distance d. A simple dynamic software module usingCAS Mathematica and Wolfram Cloud Open Access is developed. Numerical examplesare given to illustrate our results.
