Talk:Van Wijngaarden transformation

From Wikipedia, the free encyclopedia

[edit] Is this article correct?

I did a little digging around, and found this reference to the van Wijngaarden transform (defined on page 4 of the .pdf file). The transformation described in that paper is not applied to an alternating series, but is used to transform a monotone series into an alternating series. And the transformation formulae in that paper do not correspond with the formula presented in this article. So I'm a little bit confused.

Is the transformation defined in this article also described as a "van Wijngaarden transform" in the literature? Did van Wijngaarden invent several different series transformation formulas, any one of which may be called a "van Wijngaarden transform"? This article may need some help!

The description of this elegant transformation is quite incomplete. Numerical Recipes section 5.1 has a clear concise description of this transformation and shows how the tranformation can be extended from alternating series to monotone series. --24.22.30.78 16:56, 1 November 2007 (UTC)
