# SimPEG.maps.Weighting.P#

property Weighting.P#

The linear mapping operator

This property returns the sparse matrix $$\mathbf{P}$$ that carries out the weighting mapping via matrix-vector product, i.e.:

$\mathbf{u}(\mathbf{m}) = \mathbf{Pm} \;\;\;\;\; \textrm{where} \;\;\;\;\; \mathbf{P} = diag(\mathbf{w})$
Returns
scipy.sparse.csr_matrix
