Thanks, but then - how do I map "int" to all elements of my matrix M? The command
sage: map(int,M) also returns a TypeError. There's nothing wrong with the individual elements of M, as "int(M[0,0])" works fine. cheers, Alasdair On Oct 24, 6:19 pm, Nils Bruin <[email protected]> wrote: > On Oct 23, 4:40 am, Alasdair <[email protected]> wrote: > > > Here is an example: > > > sage: G.<x>=GF(2^8) > > sage: M=random_matrix(G,2,2) > > sage: map(int,M.row(0)) > > [152, 58] > > sage: map_threaded(int,M) > > TypeError: base_ring (=<type 'int'>) must be a ring > > > Why won't map_threaded work where map does? > > Note that the second arguments in the statements above are different. > Both map and map_threaded succeed and fail on the same inputs, but > with different return types and different error messages. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
