Follow-up Comment #2, bug #54729 (project octave):
In Matlab
- 'RelTol' must be a positive scalar only and throws errors otherwise, and
- 'AbsTol' must be a positive scalar or vector and throws errors otherwise,
thus
[1e-12 1e-12] or [1e-12; 1e-12] are allowed and preserved for odeset/odeget.
In both Matlab R2018a and Octave 4.4.1 we have:
>> options = odeset ('AbsTol', [1e-12 1e-12]); odeget (options, 'AbsTol')
ans =
1.0e-12 *
1.000000000000000 1.000000000000000
>> options = odeset ('AbsTol', [1e-12; 1e-12]); odeget (options, 'AbsTol')
ans =
1.0e-12 *
1.000000000000000
1.000000000000000
