graphlow.core.MeshTopology.get_skeleton

MeshTopology.get_skeleton(name: IncidenceName | AdjacencyName) → csr_array

Get or build basic skeleton (CP, PC, CC, PP, FC, CF, FP, PF). The result is cached.

Advanced API: returns a scipy.sparse matrix on the host and touches the skeleton cache. Use when you need scipy directly or explicit control over host memory.

Parameters:

nameIncidenceName | AdjacencyName

Incidence or adjacency name (CP, PC, CC, PP, FC, CF, FP, PF).

Returns:

scipy.sparse.csr_array

CSR array. dtype: np.int64
