simpeg.regularization.SmoothnessFirstOrder.cell_gradient

property SmoothnessFirstOrder.cell_gradient

Partial cell gradient operator.

Returns the partial gradient operator which takes the derivative along the orientation where smoothness is being enforced. For smoothness along the x-direction, the resulting operator would map from cell centers to x-faces.

Returns:

scipy.sparse.csr_matrix

Partial cell gradient operator defined on the regularization.RegularizationMesh.
