WebThe numerical curl of the vector field is equal to curlz = dFy_dx - dFx_dy and the angular velocity is cav = 0.5*curlz. Extended Capabilities GPU Arrays Accelerate code by running on a graphics processing unit (GPU) … WebAug 18, 2024 · [CURLZ, CAV]= curl (X,Y,U,V) computes the curl z component and angular velocity perpendicular to z (in radians per time unit) of a 2D vector field U,V. The arrays X,Y define the coordinates for U,V and must be monotonic and 2D plaid (as if produced by MESHGRID). Now I need to calculate also the potential of these vectors.

Web1. The Helmholtz-Hodge decomposition. 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 ...
