A scalar field's gradient, estimated at chosen points from samples 0.05 either side along each axis. One point gives one Vector; a point list gives a Vector List in the same order.
The field to differentiate.
Where to take the gradient: one point or a list of points.
Values the block gives besides its output. The editor lists them under Properties, and an input can read one by reference.
The vector's x component.
The vector's y component.
The vector's z component.
How long the vector is (its magnitude).
The same direction scaled to length 1.
The vector pointing the opposite way.
The point this vector reaches when started at the world origin.
This vector as a vector field with the same value everywhere.
This vector in a Vector List of one.
