is an option to EulerSum that specifies the parameter to use in the generalized Euler transformation.
- To use , you first need to load the Numerical Calculus Package using Needs["NumericalCalculus`"].
- Valid settings for are Automatic, a single ratio, or a list of ratios or pairs. In the case of a list, the various ratios are used successively in iterated Euler transformations.
- With the default setting Automatic, the value used for is based on the ratio of successive terms in the series.
