import sympy as sp

x, y, z = sp.symbols('x y z')

Fx = sp.Function('Fx')(x, y, z)

Fy = sp.Function('Fy')(x, y, z)

Fz = sp.Function('Fz')(x, y, z)

F = sp.Matrix([Fx, Fy, Fz])

nabla = sp.Matrix([sp.diff(Fx, x), sp.diff(Fy, y), sp.diff(Fz, z)])

curl_F = F.jacobian([x, y, z]).transpose() - nabla

sp.pprint(curl_F)
