ParametricBlock.deriv(m)[source]#

Derivative of the mapping with respect to the input parameters.

Let m=[σ0,σ1,xb,dx,(yb,dy,zb,dz)] be the set of model parameters the defines a block/ellipsoid within a wholespace. The mapping u(m) from the parameterized model to all active cells is given by:

The derivative of the mapping u(m) with respect to the model parameters is a numpy.ndarray of shape (nAct, nP) given by:

um=[uσ0uσ1uxbudxuybudyuzbudz)]
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.
