Re: [Help-gsl] numerical integration with strong discontinuities

[Nicolau Werneck]

How does your integrand look like?... Does it have things like (x-y)
in the denominator?... Can you show me an example of what you are
doing?

This Cauchy integration is only for integrations in one dimension,
right?... Is there any way to use it for 2 or 3 dimensions? Like doing
another numerical integration on top of it? I was thinking about
trying to run a numerical integration over a function that is the
numerical integration of the last variable on the specified point...

Are you using CERNLIB for the actual integration, or for something else?

thanks!...
