dolfinx.graph

Graph representations and operations on graphs.

Functions

adjacencylist(data[, offsets])

Create an AdjacencyList for int32 or int64 datasets.
dolfinx.graph.adjacencylist(data: np.ndarray, offsets=None)[source]

Create an AdjacencyList for int32 or int64 datasets.

Parameters:

  • data – The adjacency array. If the array is one-dimensional, offsets should be supplied. If the array is two-dimensional the number of edges per node is the second dimension.

  • offsets – The offsets array with the number of edges per node.

Returns:

An adjacency list.
