- Simulation3DMagneticField.getADeriv_rho(freq, u, v, adjoint=False)[source]#
Product of the derivative of our system matrix with respect to the model and a vector
\[\frac{\mathbf{A}(\mathbf{m}) \mathbf{v}}{d \mathbf{m}} = \mathbf{C}^{\top}\frac{d \mathbf{M^f_{\rho}}\mathbf{v}} {d\mathbf{m}}\]- Parameters
freq (float) – frequency
u (numpy.ndarray) – solution vector (nE,)
v (numpy.ndarray) – vector to take prodct with (nP,) or (nD,) for adjoint
adjoint (bool) – adjoint?
- Return type
- Returns
derivative of the system matrix times a vector (nP,) or adjoint (nD,)
