Curl of a vector matlab
WebThe vector field V and the vector X are both three-dimensional. curl( V ) returns the curl of the vector field V with respect to the vector of variables returned by symvar(V,3) . WebIf a fluid flows in three-dimensional space along a vector field, the rotation of that fluid around each point, represented as a vector, is given by the curl of the original vector field evaluated at that point. The curl vector field …

A special case of the Helmholtz-Hodge theorem states that any vector field that is tangent to the sphere can be uniquely decomposed into a sum of a surface divergence-free component and a surface curl-free component. In this Example, we show how this decomposition can be computed by Spherefun and introduce ...
