Description

Hi,
I am trying to solve a two-point bvp with ApproxFun but receive the following error:
ERROR: AssertionError: abs(last(g)) < tol
I had a hard time searching what this error is supposed to mean (is it in the documentation somewhere?), but should I interpret it as an error on my end (not properly specifying the problem)? Or is it something else?
Thanks.
