Computing the derivative of a constant is pretty fast, too. Since any interesting computation will also involve non-zero fields its not clear that you would gain much for the improved code complexity. > - evaluating their values at a given manifold point does not involve the > point coordinates in some chart. > Ditto, since there will be other fields in any interesting expression its just a question of caching the point coordinates. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
