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 $\mathit{\chi }$ from a set of magnetic permeabilities $\mathit{\mu }$. Thus the inverse mapping is defined as:

$$\mathit{\chi }(\mathit{\mu })=\frac{\mathit{\mu }}{{\mu }_0}-1$$

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.
