How can we show divergence in matlab

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: 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.
