Dear all,
Is there a reason why Sage doesn't allow you to define vector
functions using the following short hand:
sage: Q = var('x, y, z')
sage: f(Q) = [x - z, y - z]
sage: f
Q |--> (x - z, y - z)
I would have expected/liked the last line to be
sage: f
(x, y, z) |--> (x - z, y - z)
This would help us to deal with vector functions in a more systematic
way. More specifically, it would be a great help in FEM, Lagrangian/
Hamiltonian mechanics, etc, where you have one function to begin with,
which is then subjected to a great deal of easily formalizable
symbolic computations.
Looking forward to your comments!
Joris
