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.
