# SimPEG.maps.ReciprocalMap.inverse#

ReciprocalMap.inverse(D)[source]#

Apply the inverse of the reciprocal mapping to an array.

For the reciprocal mapping $$\mathbf{u}(\mathbf{m})$$, the inverse mapping on a variable $$\mathbf{x}$$ is itself a reciprocal mapping, i.e.:

$\mathbf{m} = \mathbf{u}^{-1}(\mathbf{x}) = \mathbf{x}^{-1}$
Parameters
Dnumpy.ndarray

A set of input values

Returns
numpy.ndarray

A numpy.ndarray containing result of applying the inverse mapping to the elements in D; which in this case is just a reciprocal mapping.
