simpeg.potential_fields.base.BaseEquivalentSourceLayerSimulation.getJ#
- BaseEquivalentSourceLayerSimulation.getJ(m, f=None)[source]#
Returns the full Jacobian.
The general definition of the linear forward simulation is:
where
is a mapping operator (optional) from the model space to a user-defined parameter space, and is an (n_data, n_param) linear operator. ThegetJ
method forms and returns the full Jacobian:for the model
provided. When is the identity map (default), the Jacobian is no longer model-dependent and reduces to:- Parameters:
- m
numpy.ndarray
The model vector.
- f
None
Precomputed fields are not used to speed up the computation of the Jacobian for linear problems.
