Thomas Neidhart updated MATH-1015:
----------------------------------
Attachment: LaguerreTest.java
GaussIntegratorFactory.java
LaguerreRuleFactory.java
Attached a first version to support Gauss-Laguerre quadrature.
> Improper integration with one infinite limit
> --------------------------------------------
>
> Key: MATH-1015
> URL: https://issues.apache.org/jira/browse/MATH-1015
> Project: Commons Math
> Issue Type: New Feature
> Reporter: Ajo Fod
> Priority: Minor
> Attachments: GaussIntegratorFactory.java, LaguerreRuleFactory.java,
> LaguerreTest.java
>
>
> This is about integrating a f(x) in [c, Inf] or in [-Inf, c]
> Gauss-Laguerre (GL) can be used to integrate between [0, Inf]
> http://en.wikipedia.org/wiki/Gauss%E2%80%93Laguerre_quadrature
> With the change of variables using f(g(x))
> where g(x) = -x
> GL can be used to integrate in [-Inf,0]
> With another change of variables:
> g(x) = x+c
> one could integrate in [c, Inf]
