That's because m.exp() first changes the ring to SR and then calls "exp" on that result. For dense matrices that works. For sparse matrices it doesn't. One fix would be to change "exp" on sparse matrices to
self.dense_matrix().change_ring(SR).exp() -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
