Hi everyone!
It seems strange to me, but I am not finding in the forum any previous post to the subject. I need to calculate the Complete Elliptic Integral of the 2nd kind.
Since it will be evaluated many times inside a double loop, it would be probably unwise to define it using its "integral definition", because of performance.
(from Wikipedia... sorry, I am not a mathematician...)
Has someone good advice for me? What I am going to try is to use the "Gauss hypergeometric function" that seems to be available in Mathcad (fhyper)
Nevertheless I am unsure if this is a good idea.
Thanks a lot for any hints
Best regards
Claudio
