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.
