WebOperators for vector calculus#. This module defines the following operators for scalar, vector and tensor fields on any pseudo-Riemannian manifold (see pseudo_riemannian), and in particular on Euclidean spaces (see euclidean): grad(): gradient of a scalar field div(): divergence of a vector field, and more generally of a tensor field curl(): curl of a vector … Webnumpy.gradient. #. Return the gradient of an N-dimensional array. The gradient is computed using second order accurate central differences in the interior points and either first or second order accurate one-sides (forward or backwards) differences at the boundaries. The returned gradient hence has the same shape as the input array. simrad cape town
