Update of bug #38499 (project octave):
Status: None => Fixed
Open/Closed: Open => Closed
_______________________________________________________
Follow-up Comment #3:
The ode45 function has been moved into core Octave in the development branch
(it will be in Octave 4.2) and has undergone a lot of modifications.
With the current version I see:
>> [t,u] = ode45(@(t,u) [0 1], [0 500], [0 0], odeset ());
warning: Option 'RelTol' not set, new value 0.001000 is used
warning: called from
ode45 at line 181 column 5
warning: Option 'AbsTol' not set, new value 0.000001 is used
warning: called from
ode45 at line 193 column 5
warning: option 'InitialStep' not set, estimated value 0.000100 is used
warning: called from
ode45 at line 270 column 5
warning: Option 'MaxStep' not set, new value 50.000000 is used
warning: called from
ode45 at line 281 column 5
so it seems this bug is not there anymore.
i am closing this ticket, please post a new bug if you see other problems with
ode45.
