Then its gradient ∇ f ( x, y, z) = ( ∂ f ∂ x ( x, y, z), ∂ f ∂ y ( x, y, z), ∂ f ∂ z ( x, y, z)) is a vector field, which we denote by F = ∇ f . We can easily calculate that the curl of F is zero. We use the formula for curl F in terms of its components

WebFeb 5, 2024 · You have to keep in mind that a vector field is not just a set of functions, but also a domain. For instance, the vector field F = − y x 2 + y 2, x x 2 + y 2 on the set U = { ( x, y) ≠ ( 0, 0) } has a curl of zero. WebJan 1, 2024 · To calculate the curl of a vector function you can also use numdifftools for automatic numerical differentiation without a detour through symbolic differentiation. Numdifftools doesn't provide a curl() function, but it does compute the Jacobian matrix of a vector valued function of one or more variables, and this provides the derivatives of all …
