I've verified the curl vs wikipedia and defined rot as the z-component
of the curl of the 2D vector operand embedded in 3D. Is that right?


rot is just a synonym for curl. For simplicity, I would remove rot.


I'm used to the following notation (in pseudo-math):

  rot:  R^2 --> R
  curl: R   --> R^2
  curl: R^3 --> R^3

Must be a Scandinavian thing. All the references I'm finding on the net saythat curl and rot are the same.
