I don't understand the question. Are you asking if it's possible to use the special notation like `f(x) = x^2`

for the creation of vector valued functions? If so, the answer is currently **no**, but it could probably be added to the Sage preparser without much problem. Of course you can always define the function `rot`

the ordinary way to take a vector and return a vector:

```
sage: rot = lambda v: vector([1/v[0],1,1])
sage: rot(vector([2,1,1]))
(1/2, 1, 1)
```
