Follow-up Comment #4, bug #47654 (project octave):
I have version R2016a, but I was wrong: Matlab is able to construct odeset
with AbsTol or/and RelTol equal to zero.
What Matlab doesn't allow to do is to use inside ode23 and ode45 these
options.
The output I posted was an error from the call to ode23 and ode45 and was not
regarding odeset, that had correctly constructed the option struct.
The changeset I prepared fix the bug in odeset but allow ode23 and ode45 to
receive AbsTol or RelTol equal to zero as input. This could be considered as
an extension of Matlab code, or as an incompatibility. If this is the case, I
will modify the code of these solvers in order to give the same output as
Matlab (an error).
