Numerical Integration Routines

Hello,

Is there any MKL routine for numerical integration?

We are interesting in numerical integration in a semiinfinite region and our integrand is oscillating but it decay quikly to zero (like a Lipschitz function exp(-ax)*Jo(bx)).

Thank you very much

Gianluca

The source code of Quadpack is in Fortran. In principle, you can build a DLL from that and call the routines from C and Fortran. On top of that, using well-known procedures, you could in principle use the DLL from C#. I don't use C# much, so I cannot comment on the basis of personal experience.

See also the IMSL C# library, http://docs.roguewave.com/imsl/net/6.5.2/manual/docs/api/html/Example/Math/QuadratureEx4.html, and the similar NAG C# numerical library.

ok thank you,

but is it your intention to integrate these procedures in MKL in the future?

At the moment, we don't want to use other lib than MKL.

Guinluca, currently we don't have such plans. at least at the nearest (next ) version of MKl 2018.

I forgot to mention another library/framework that you may wish to consider: ALGLIB, at www.alglib.net/integration.

You are welcome to bring your numerical methods questions to this forum. Even when a particular topic is not covered in MKL, it is relevant to consider how to link external software with MKL. Both IMSL and NAG do this concerning their libraries.
