ElectricDipoleWholeSpace.vector_distance(xyz)#

Vector distance to a set of gridded xyz locations.

Where $$\mathbf{p}$$ is the location of the source and $$\mathbf{q}$$ is a point in 3D space, this method returns the vector distance:

$\mathbf{v} = \mathbf{q} - \mathbf{p}$

for all locations $$\mathbf{q}$$ supplied in the inputed argument xyz. For dipoles, $$\mathbf{p}$$ is the dipole location. For circular loops, $$\mathbf{p}$$ defines the center location for the loop.

Parameters
xyz(n, 3) numpy.ndarray

Gridded xyz locations

Returns
(n, 3) numpy.ndarray

Vector distances in the x, y and z directions
