Webc = curl (V,X) returns the curl of symbolic vector field V with respect to vector X in three-dimensional Cartesian coordinates. Both the vector field V and the vector X must be vectors with three components. c = curl (V) returns the curl of the vector field V with respect to a default vector constructed from the symbolic variables in V. WebMar 12, 2024 · Its obvious that if the curl of some vector field is 0, there has to be scalar potential for that vector space. ∇ × G = 0 ⇒ ∃ ∇ f = G This clear if you apply stokes theorem here: ∫ S ( ∇ × G) ⋅ d A = ∮ C ( G) ⋅ d l = 0 And this is only possible when G has scalar potential. Hence proved. But now considering the converse of the statement..
