Web19 de out. de 2024 · 1 Answer Sorted by: 2 As stated by Ninad, If T has a divergence it must be a vector field. And vector fields don't have gradients. But I think I see what you are looking for. If you have a vector field with divergence 0, it means your function T can be expressed as the curl of some other function ( locally ). Why is that? It helps to notice that: WebCompute the numerical divergence of the vector field. div = divergence (x,y,z,u,v,w); Display the divergence of vector volume data as slice planes.

Web7 de set. de 2024 · Figure 16.5.1: (a) Vector field 1, 2 has zero divergence. (b) Vector field − y, x also has zero divergence. By contrast, consider radial vector field ⇀ R(x, y) = − x, − y in Figure 16.5.2. At any given point, more fluid is flowing in than is flowing out, and therefore the “outgoingness” of the field is negative. biotechnology stocks
