Divergence matlab

Jun 18, 2019 · Let's forget Matlab for a moment. What is the del (or nabla) operator? When you dot this with a vector, you get the divergence. In your case, all the components of the vectors are constants (as you know all the components). So doing a partial derivative on any of them will result in 0. This problem is occurring because your vectors are random. Verify the Divergence theorem if F(x, y, z) =<x^2y^2, y^2z^2 , z^2x^2> and the solid E is bounded by x^2 + y^2 + z^2 = 2 on top and z = (x^2+y^2)^1/2 on the bottom.
