simpeg.maps.Mesh2Mesh.deriv#
- Mesh2Mesh.deriv(m, v=None)[source]#
Compute derivative of the mapping with respect to the model.
- Parameters:
- m(n_param,)
numpy.ndarray The model parameters
- v(n_param,)
numpy.ndarray,optional A vector.
- m(n_param,)
- Returns:
numpy.ndarrayWhen v is
None, a (n_cells, n_param) numpy.ndaray is returned which represents the derivative of the mapping with respect to the model. When v is a vector, an (n_cells,) numpy.ndarray representing the derivative of the mapping times the vector is returned.
