Hello ! 

I have an integral to perform 4096 times: it is a 3dimensionnal integral over a matrix of 4096.4096 points.

It takes many hours and I still does not have the result. I made a loop with NIntegrate.

Is it possible that an integration loop in mathematica takes so long ? Is there any ways to improve it ?

Thank you

Lena
