> I suggest that you separate the time taken for the change_ring() operation
Thanks. You are right, the .change_ring() was written in a hurry. If the sage overlords want more systematic QA, they will need moderate budget. I need to compute large m-th powers of matrices for m > 100 and if I work over ZZ, the integer entries are very large, slowing the wall time computation. pari/gp has decent performance for matrix multiplication over finite fields. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
