RE: Method to eliminate NIntegrate warning

All depends on what you are trying to NIntegrate ! In this kind of
situation, please post your example more explicitely, nothing can be
done without it.

Objet:	[mg10481] Method to eliminate NIntegrate warning

I want to know the method to eliminate NIntegrate warning.

The two warning message follows :

   Numerical integration converging too slowly;
     suspect one of the following: singularity,
     oscillatory integrand, or insufficient

   NIntegrate failed to converge to prescribed
     accuracy after 7 recursive bisections in x near
    x = 0.126684.

How can I escape from this problem ? When above-case happened, can I
believe the accuracy of my data ?
