WebRather than thinking about fluid rotation in a large region, curl is supposed to measure how fluid tends to rotate near a point. Concept check: The vector field from the previous example is a little bit special in that the … 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 …
