graphlow.core.MeshTopology.get_derived_skeleton

MeshTopology.get_derived_skeleton(derived: DerivedMatrixName, name: AdjacencyName) → csr_array

Get or build derived skeleton (Laplacian, Degree, etc.). 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:

derivedDerivedMatrixName

Derived matrix name (Laplacian, Degree, etc.).

nameAdjacencyName

Adjacency name (CC, PP).

Returns:

scipy.sparse.csr_array

CSR array. dtype: np.float64
