Hi Everyone;
 I've tracked down the slow operation of my Mathematica simulation code to 
lie in the ListIntegrate command:

G[n_] := ListIntegrate[xsec Phi[n], 1]

where both xsec and Phi[n] are 400 values long.

Is there a way to speed up ListIntegrate via Compile or a similar technique?

Thanks in advance and best regards,

Matt
