The following all works
sage: a = sqrt(2)*sqrt(3)*sqrt(6)
sage: v = vector([a])
sage: M = Matrix([v, v])
sage: a.canonicalize_radical()
6
sage: v.canonicalize_radical()
(6)
However the following doesn't work:
sage: M = Matrix([v, v])
sage: M.canonicalize_radical()
EDIT: Could somebody please tell me the right place to ask for "vectorization of canonicalize_radical for matrices" as a new feature of sage?
Like that:
sage: M.apply_map(lambda u: u.canonicalize_radical())

Yes, I know that I can write some code to do want I want (and I have done so!). However, as my question states, I am asking for a feature to be implemented - namely the simplify methods should work the same for "scalars", "vectors", and "matrices". In any case, thank you for the reply.
In the end, I went with
M = Matrix([v.canonicalize_radical() for v in M])
because it feels a bit more "pythonic". I suppose what I really want is to be told how to make a feature request. I'll add that to the original question.
Regarding your last question, ask.sagemath is not a bad place since quite a lot of developers are looking around, see the tags confirmed_bug and fixed_bug.
However, since you are able to add the feature yourself and since we need more developers, let me suggest you to:
src/sage/matrix/matrix_symbolic_dense.pyx following the existing simplify_full method)EDIT : during sage days 75, Fangan Dosso opened and filled trac ticket 21332 about that, so the feature will be available in the next versions of Sage.
