SimPEG.maps.ChiMap.inverse#

ChiMap.inverse(m)[source]#

Apply the inverse mapping to an array.

For the ChiMap class, the inverse mapping recoveres the set of magnetic susceptibilities \(\boldsymbol{\chi}\) from a set of magnetic permeabilities \(\boldsymbol{\mu}\). Thus the inverse mapping is defined as:

\[\boldsymbol{\chi}(\boldsymbol{\mu}) = \frac{\boldsymbol{\mu}}{\mu_0} - 1\]

where \(\mu_0\) is the permeability of free space.

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 represents the conversion of magnetic permeabilities to their corresponding magnetic susceptibility values.
