There is some issue with this when trying to use set comprehension, see http://ask.sagemath.org/question/30102/how-do-i-define-and-work-with-a-set-of-matrices/ Perhaps should we have a "mutable" argument (True by default to be consistent with the current behaviour) in the matrix/vector constructors, so that we can do: {vector(m.row(0), mutable=False) for m in blah} Ciao, Thierry -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
