More like a Jacobian operator. I believe the module is about vectors as geometrical entities, not matrices. > And do not forget about Hessians too. I think that Hessians will be of very little use in this module, as they are very clumsy to represent geometrically. Nonetheless they would be an amusing addition at the later stages. -- You received this message because you are subscribed to the Google Groups "sympy" group.
