> About dual vectors; I haven't read about dual vectors as of yet. If you wish you can think of the dual of a vector (a one-form) as a one row matrix (and the vector as a one column matrix).
If you have a scalar product operation defined there is a canonical way to get a dual of a vector. For the vector v and scalar product <,>, the oneform for the vector is v' such that v'(v) = <v, v> -- You received this message because you are subscribed to the Google Groups "sympy" group.
