Gradient in tensor notation
http://usuarios.geofisica.unam.mx/cruz/Sismologia2/indicial_tensor.pdf WebNote each term in the gradient tensor is described in tensor notation: $$\nabla \vec v_{ij}=\nabla_j\vec v \cdot e_i$$ Where $\nabla_j$ means jth component of del operator. Apply this to each term in gradient tensor as below.
