RipsComplex
¶ Bases:
object
The data structure is a one skeleton graph, or Rips graph, containing edges when the edge length is less or equal to a given threshold. Edge length is computed from a user given point cloud with a given distance function, or a distance matrix.
-
__init__
()¶ RipsComplex constructor.
- Parameters
Or
- Parameters
distance_matrix¶ – A distance matrix (full square or lower triangular).
And in both cases
- Parameters
sparse¶ (float) – If this is not None, it switches to building a sparse Rips and represents the approximation parameter epsilon.

WeightedRipsComplex
(distance_matrix, weights=None, max_filtration=inf)[source]¶ Bases:
object
Class to generate a weighted Rips complex from a distance matrix and weights on vertices, in the way described in [1]. Remark that all the filtration values are doubled compared to the definition in the paper for the consistency with RipsComplex.
