d_dx
(points)[source]¶ The first order derivative of this spatial object with respect to spatial changes evaluated at points.
- Parameters
points (
(n_points, n_dims)
ndarray) – The spatial points at which the derivative should be evaluated.- Returns
d_dx (
(n_points, n_dims, n_dims)
ndarray) – The Jacobian wrt spatial changes.d_dx[i, j, k]
is the scalar differential change that thej
’th dimension of thei
’th point experiences due to a first order change in thek
’th dimension.It may be the case that the Jacobian is constant across space - in this case axis zero may have length
1
to allow for broadcasting.
