[Octave-bug-tracker] [bug #62412] quadcc does not warn when quadrature fails to converge

[Nicholas Jankowski]

Update of bug #62412 (project octave):

                  Status:               Confirmed => Patch Submitted

Follow-up Comment #13:

Re: adding a quadcc warning, I think just the following should suffice just
before the final return statements:


  if (err > std::max (abstol, fabs (igral) * reltol)
    warning ("quadcc: Error tolerance not met. Estimated error: %e\n", err);


the attached patch does that, but since i'm not set up to build and test
didn't want to push it into quadcc.  it doesn't check if nargin>1 first, but i
noticed quadgk warns whether err is requested or not, so figured this could do
similarly.
