- Simulation3DNodal.getJ(m, f=None)[source]#
Compute the sensitivity matrix for a given model.
Where \(\mathbf{d}\) are the data, \(\mathbf{m}\) are the model parameters, and the sensitivity matrix is defined as:
\[\mathbf{J} = \dfrac{\partial \mathbf{d}}{\partial \mathbf{m}}\]this method computes and returns the sensitivity matrix.
- Parameters:
- m(n_param,)
numpy.ndarray The model parameters.
- f
resistivity.fields.FieldsDC,optional Fields solved for all sources.
- m(n_param,)
- Returns:
- (
n_data,n_param)numpy.ndarray The sensitivity matrix times.
