Hello, Does anyone know if it is possible to define an arbitrary vector in Mathematica? What I mean by this, is can I tell Mathematica that a particular variable is a vector, without having to define the components of this vector? I'd like to be able to manipulate vectors with an arbitrary number of components, but am not sure if this is possible in Mathematica. Many thanks, James
