Dear GSL Helpers,
We tried to use the qagiu algorithm to calculate the following integration
\int_0^infty dx cosh(x) e^{-cosh(x)} ,
however qagiu falls and complains on "bad integrand behavior". If we're
using qags with a fixed big upper limit, the integral is fine.
Do you have any suggestion what could be the problem? We'd like to
use qagiu without upper limit.
