SimPEG.maps.SphericalSystem.deriv#
- SphericalSystem.deriv(m, v=None)[source]#
Derivative of mapping with respect to the input parameters
- Parameters
- m(
nP)numpy.ndarray A vector representing a set of model parameters
- v(
nP)numpy.ndarray If not
None, the method returns the derivative times the vector v
- m(
- Returns
scipy.sparse.csr_matrixDerivative of the mapping with respect to the model parameters. If the input argument v is not
None, the method returns the derivative times the vector v.
