Find gradient vector of a function
WebJun 11, 2012 · It depends on how you define the gradient operator. In geometric calculus, we have the identity ∇ A = ∇ ⋅ A + ∇ ∧ A, where A is a multivector field. A vector field is a specific type of multivector field, so this same formula works for v → ( x, y, z) as well. So we get ∇ v → = ∇ ⋅ v → + ∇ ∧ v →. WebGradient is calculated only along the given axis or axes The default (axis = None) is to calculate the gradient for all the axes of the input array. axis may be negative, in which case it counts from the last to the first axis.
