simpeg.maps.ParametricBlock.deriv#
- ParametricBlock.deriv(m)[source]#
Derivative of the mapping with respect to the input parameters.
Let
be the set of model parameters the defines a block/ellipsoid within a wholespace. The mapping from the parameterized model to all active cells is given by:The derivative of the mapping
with respect to the model parameters is anumpy.ndarray
of shape (nAct, nP) given by:- 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_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.
