# SimPEG.maps.LogMap.inverse#

LogMap.inverse(m)[source]#

Apply the inverse of the natural log mapping to an array.

For the natural log mapping $$\mathbf{u}(\mathbf{m})$$, the inverse mapping on a variable $$\mathbf{x}$$ is performed by taking the natural exponent of the elements, i.e.:

$\mathbf{m} = \mathbf{u}^{-1}(\mathbf{x}) = exp(\mathbf{x})$
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 the natural exponent.
