However, since the purpose of this matrix is for computing nodal
averages, simpler matrices can sometimes be used, such as an identity or
permutation matrix that assigns the value at each node to that of a
specific integration point. Element subclasses may override this method
to supply such simplified matrices.getNodalAveragingMatrix in class FemElement3dBasepublic MatrixNd getNodalExtrapolationMatrix()
