Hello, Thanks for the bug report. The result is a bit unintuitive for x1==0 but it is following the inequality in the documentation. For roots close to zero, add a small epsabs term like GSL_DBL_MIN to work around it. I'll consider changing the behaviour in future to make it more obvious. -- best regards, Brian Gough Network Theory Ltd, Publishing the GSL Manual - http://www.network-theory.co.uk/gsl/manual/ _______________________________________________ Bug-gsl mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-gsl
