cechmate.filtrations.Cech

class cechmate.filtrations.Cech(maxdim=None, verbose=True)

Compute the Cech filtration of a Euclidean point set for simplices up to order self.max_dim.

Examples

>>> r = Cech(maxdim=1)
>>> simplices = r.build(X)
>>> diagrams = r.diagrams(simplices)

__init__(maxdim=None, verbose=True)

Default constructor

Parameters

• maxdim (int) – Maximum dimension of homology to compute

• verbose (boolean) – If True, then print logging statements.

Methods

__init__([maxdim, verbose])	Default constructor
build(X)	Compute the Cech filtration of a Euclidean point set for simplices up to order self.max_dim.
diagrams([simplices, show_inf])	Compute persistence diagrams for the simplices.
