That looks good, right? What about arg(z). What are the Wirtinger derivatives of arg(z)? Do you have other examples of non-analytic functions? Would you mind posting your patch to FriCAS somewhere? I would be interested in how you implemented it. Ondrej -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
