Simulation3DMagneticField.getJ(m, f=None)[source]#

Generate the full sensitivity matrix.

This method generates and stores the full sensitivity matrix for the model provided. I.e.:

$$\mathbf{J}={\displaystyle \frac{\partial \mathbf{d}}{\partial \mathbf{m}}}$$

where $\mathbf{d}$ are the data and $\mathbf{m}$ are the model parameters.

Parameters:

m(n_param,) numpy.ndarray

The model parameters.

fstatic.resistivity.fields.FieldsDC, optional

Fields solved for all sources.

Returns:

(n_data, n_param) numpy.ndarray

The full sensitivity matrix.
