WebMar 12, 2024 · 1. You might also write your expression as: ∇f = grad(f) = n ∑ i = 1 ∂f ∂xiei Which for 3 dimensions i = 1, 2, 3 and e = i, j, k, note e is your basis or in this case unit vector. Thus, you obtain a 3x1 or 1x3 vector depending on your convention. WebMain article: Divergence. In Cartesian coordinates, the divergence of a continuously differentiable vector field is the scalar-valued function: As the name implies the divergence is a measure of how much vectors are diverging. The divergence of a tensor field of non-zero order k is written as , a contraction to a tensor field of order k − 1. rccp precious remove
