SimPEG.maps.LogMap#

class SimPEG.maps.LogMap(mesh=None, nP=None, **kwargs)[source]#

Mapping that computes the natural logarithm of the model parameters.

Where $$\mathbf{m}$$ is a set of model parameters, LogMap creates a mapping $$\mathbf{u}(\mathbf{m})$$ that computes the natural logarithm of every element in $$\mathbf{m}$$; i.e.:

$\mathbf{u}(\mathbf{m}) = \textrm{log}(\mathbf{m})$
Parameters
meshdiscretize.BaseMesh

The number of parameters accepted by the mapping is set to equal the number of mesh cells.

nPint

Set the number of parameters accepted by the mapping directly. Used if the number of parameters is known. Used generally when the number of parameters is not equal to the number of cells in a mesh.

Methods

 deriv(m[, v]) Derivative of mapping with respect to the input parameters. Apply the inverse of the natural log mapping to an array.
