It would seem to me that libgap should be able to do the translation pretty efficiently. My first suspicion would be that you hit some generic translation cop-out. Something that reverts to strings or so? I would also do some timings to see how this scales: it should be roughly linear in input. If it seems to be something worse, then that might be an indication there's a wrong algorithm involved somewhere. How fast is converting your list of matrices to a list of lists in gap? Perhaps GapMatrix->GapList->SageList->SageMatrix is faster. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
