6.21.5 Rotational: curl
The curl of a three-dimensional vector field
F=[F1,F2,F3] with variables [x1,x2,x3]
The curl command computes the curl of a three dimensional
vector field (note that it must be three dimensional).
curl takes two arguments:
F, a three-dimensional vector field, given as a list of
three expressions depending on three variables.
- vars, a list of the three variable names.
- curl(F,vars) returns the curl of
the vector field.
