# geoana.em.fdem.MagneticDipoleHalfSpace.dot_orientation#

MagneticDipoleHalfSpace.dot_orientation(vecs)#

Dot product between the orientation of the source and a gridded set of vectors.

Where $$\mathbf{p}$$ is the vector defining the dipole moment direction and $$\mathbf{v}$$ is a 3D vector, this method returns the dot product:

$\mathbf{p} \cdot \mathbf{v}$

for all vectors $$\mathbf{v}$$ supplied in the input argument vecs.

Parameters
vecs(n, 3) numpy.ndarray

A set of 3D vectors

Returns
1. numpy.ndarray Dot product between the dipole moment direction (orientation) and each vector supplied.
