SimPEG.electromagnetics.frequency_domain.sources.MagDipole_Bfield.evalDeriv#
- MagDipole_Bfield.evalDeriv(simulation, v=None, adjoint=False)[source]#
- Return derivative of the magnetic and electric source terms with respect to the model. - Parameters
- simulationSimPEG.electromagnetics.base.BaseEMSimulation
- An instance of an electromagnetic simulation 
- vnp.ndarray
- A vector 
- adjointbool
- If - True, return the adjoint operation
 
- simulation
- Returns
- tuple
- A tuple (s_mDeriv, s_eDerive). If v is not - None, the method returns the derivatives of the magnetic and electric sources times the vector v. If v is- None, the method returns the functions for multiplying the derivatives with a vector.
