Hello!
Kind of a n00b question: Do Cauchy principal value integrators require
that the pole in the integrand be a simple pole? In other words, will
gsl_integration_qawc
work even
if my integrand looks like f(p)/g(p), where I know that g(p_0)=0 for some
p_0, but my integrand is not necessarily of the form f(p)/(p-p_0) ? And what
about
for the CERNLIB routine RCauchy?
Thanks,
Andrew
