How are list of matrices printed by sage?
If I construct a list of matrices and let sage print it, the matrices are (correctly) aligned on the top:
sage: A=matrix([[1,2],[3,4]]) sage: [A,A] [ [1 2] [1 2] [3 4], [3 4] ]
Howewer, this is not the output of the __repr__ function of a list: compare:
sage: print [A,A].__repr__() [[1 2] [3 4], [1 2] [3 4]]
I would like to construct an object whose output is on more than one lines (like a matrix), and I would like a list of these objects to be printed aligned on the top (like with the matrices in the first example above). How can I do that?
