simpeg.maps.LinearMap#

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

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.
`is_linear`	Determine whether or not this mapping is a linear operation.
`mesh`	The mesh used for the mapping
`nP`	Number of parameters the mapping acts on.
`shape`	Dimensions of the mapping operator

Methods

`deriv`(m[, v])	Derivative of the mapping with respect to the input parameters.
`dot`(map1)	Multiply two mappings to create a `simpeg.maps.ComboMap`.
`inverse`(D)	The transform inverse is not implemented.
`test`([m, num, random_seed])	Derivative test for the mapping.
