simpeg.data_misfit.L2DataMisfit.W#
- property L2DataMisfit.W#
The data weighting matrix.
For a discrete least-squares data misfit function of the form:
\[\phi_d (\mathbf{m}) = \| \mathbf{W} \mathbf{f}(\mathbf{m}) \|_2^2\]\(\mathbf{W}\) is a linear weighting matrix, \(\mathbf{m}\) is the model vector, and \(\mathbf{f}\) is a discrete mapping function that acts on the model vector.
- Returns:
scipy.sparse.csr_matrix
The data weighting matrix.
