Hello [userlink]Danevangx[/userlink]

You can use the function vectorize(), a loop, or ranged indices... choose the one that fit your needs

This is NOT unit vector. My understanding is that you want
a general procedure to differentiate a function vector.
This simple demo procedure is the core algorithm in Smath fitting functions

Here is another one. Maxima has generic vector-/matrix handling
