SimPEG.maps.LinearMap#

class SimPEG.maps.LinearMap(A, b=None, **kwargs)[source]#

Bases: SimPEG.maps.IdentityMap

A generalized linear mapping.

A simple map that implements the linear mapping,

>>> y = A @ x + b
Parameters
A(M, N) array_like, optional

The matrix operator, can be any object that implements __matmul__ and has a shape attribute.

b(M) array_like, optional

Additive part of the linear operation.

Attributes

A

The linear operator matrix.

b

Added part of the linear operation.

shape

Dimensions of the mapping operator

Methods

deriv(m[, v])

Derivative of the mapping with respect to the input parameters.
