Update of bug #47654 (project octave):

                  Status:             In Progress => Need Info              
                 Summary: odeset does not allow zero value for tolerance =>
ode23/ode45 do not allow zero value for tolerance

    _______________________________________________________

Follow-up Comment #5:

The current Octave code allows setting AbsTol or RelTol to 0.  However, ode23
will not allow a 0 for either tolerance.


error: ode23: RelTol must be positive
error: called from
    validateattributes at line 406 column 7
    odemergeopts at line 27 column 9
    ode23 at line 167 column 11


This is Matlab compatible.  Is that good enough and we can close this report?

Testing was done on the development branch with cset 86bb7c37a1b9.
