13.7.5 Rotational

The curl of a three-dimensional vector field F=[F1,F2,F3] with variables [x1,x2,x3] is

  curl F=

.

The curl command computes the curl of a three dimensional vector field (note that it must be three dimensional).

Example

curl([x*z,-y^2,2*x^y],[x,y,z])
     

2 lnx· xy,x−2 yxy−1,0
