Laguerre is defined only in [0,+ve Inf] Hermite is defined in [-Inf,+Inf] I have two issues with the above: 1: Cant imagine how someone would use AQ. Which means as Gilles noticed, you can't focus on the hard to converge sections of the integral. 2: If you use the integration without AQ. Any funct

The math is quite simple. What is not clear is what the numerical properties are for substitution of the sort being advocated. Which functions will do better with substitution? Which will do better with Laguerre polynomials? On Sat, Jul 20, 2013 at 8:59 AM, Ajo Fod wrote: > The method is de

The method is described here: http://en.wikipedia.org/wiki/Integration_by_substitution My patch uses it for improper integration via the change of variable t/(1-t^2) as suggested in : http://en.wikipedia.org/wiki/Numerical_integration Please reach back if anyone understands this concept. Cheers,
