io.sparse_to_sets

io.sparse_to_sets(subsets, reindex=False)

Converts a collection of sets into a sparse CSC array.

This function converts a a sparse matrix into list of integer-valued arrays, where each array represents a subset. Optionally, if the sets themselves do not represent 0-based indices, you can set reindex=True to map the rows and columns to the base index set \([n] = {0, 1, ..., n - 1}\).

Parameters

Name	Type	Description	Default
subsets	sparray	sparse array in canonical form.	required
reindex	bool	whether to reindex the sets to the base index set. Default to False.	False

Returns

Type	Description
csc_array	Collection of indices representing subsets.
