SimPEG.maps.ReciprocalMap#

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

Bases: IdentityMap

Mapping that computes the reciprocals of the model parameters.

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

\[\mathbf{u}(\mathbf{m}) = \mathbf{m}^{-1}\]
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.

Attributes

is_linear

Determine whether or not this mapping is a linear operation.

Methods

deriv(m[, v])

Derivative of mapping with respect to the input parameters.

inverse(D)

Apply the inverse of the reciprocal mapping to an array.
