What is the bug here? Do you think matrix(2,3,1) should succeed? Do you think it should produce a different error message? The following behaviour seems quite reasonable to me: sage: MatrixSpace(ZZ,2,2)(5) [5 0] [0 5] sage: MatrixSpace(ZZ,2,3)(5) TypeError: nonzero scalar matrix must be square Although: sage: MatrixSpace(ZZ,2,3)(0) [0 0 0] [0 0 0] suggests this should perhaps be a ValueError I wouldn't mind if the latter would not work, since the following does: sage: MatrixSpace(ZZ,2,3).zero() [0 0 0] [0 0 0] -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
