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. WebOne is to use the ∇∇ operator, sympy provides the class Del (), the methods of this class are: cross, dot and gradient, cross is the cross product, which calculates the curl, dot is the dot product, which is used to calculate the divergence, gradient Naturally, the gradient is calculated.
