simpeg.data_misfit.BaseDataMisfit.W#

property BaseDataMisfit.W#

The data weighting matrix.

For a discrete least-squares data misfit function of the form:

$${\varphi }_d(\mathbf{m})=\Vert \mathbf{W}\mathbf{f}(\mathbf{m}){\Vert }_2^2$$

$\mathbf{W}$ 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.
