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

Returns:
scipy.sparse.csr_matrix

Derivative 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.
