graphlow.core.MeshTopology.face_point_incidence

MeshTopology.face_point_incidence(layout: Literal['csr', 'coo'] = 'coo') → T

Materialize face-point incidence (FP).

Parameters:

layoutLiteral[“csr”, “coo”]

Layout of the sparse matrix. Default is “coo”.

Returns:

T

Backend tensor of shape (n_faces, n_points). dtype is float with the precision set by the backend.

Notes

Here, “face” means a face of a volume mesh. This method does not apply to surface meshes. For surface meshes, use cell_point_incidence() instead.
