Discretization of Fractional Operators: Analysis by Means of Advanced Computational Techniques

This paper studies the discretization of fractional operators by means advanced clustering methods. The Grünwald–Letnikov operator is approximated series generated Euler, Tustin and generalized mean. for different orders form objects to be assessed. For this purpose, several distances associated with hierarchical multidimensional scaling computational techniques are tested. Arc-cosine distance 3-dim produce good results. visualization graphical representations allows a better understanding properties embedded in each type approximation operators.
