filtrations.SetFiltration.SetFiltration

filtrations.SetFiltration.SetFiltration(self, simplices=None, f=None, order='lex')

Filtered complex of simplices uses SortedSet.

This class represents a filtration of simplices by associating keys of a given index set with _SortedSet_s of Simplex instances. This class also implements the Mapping[Any, SimplexConvertible] Implements: getitem, iter, len, contains, keys, items, values, get, eq, and ne
