Octave compatibility

We wish to keep RepLAB fully accessible for free. For this reason, the code is adapted to run within Octave’s specificities. For instance, we avoid calling long chains of constructors which can cause problem. It is also important to avoid calling ‘clear all’ within the tests or in the documentation since this may clear test data while tests are running on some versions of Octave.

Note that some limitations may also apply on Octave only. For instance, Octave doesn’t allow for clickable links to be created in the display, and it does not support saving/loading class objects. It is also

Here is a list of Octave bugs that are problematic to the project. Their resolution will allow to improve the library.

Bugs affecting replab.CommutantVar:

• 51317: to enable automatic copy of handle classes

• 54941: to split the class methods into individual files

• 56864: to set up the proper class precedence with respect to yalmip objects (due to this bug, addition of replab.CommutantVar and sdpvar is not commutative (!))

• 44498: isscalar(sdpvar(3)) returns 1 on octave

Bugs affecting other parts

• isequal fails in Octave when objects reference themselves; i.e. our replab.NiceFiniteGroup base instance has self.parent.parent == self.parent and that throws Octave’s isequal in a loop
