Utilities

Alpha complex

Alpha complex utilities compute Alpha complex persistence from a point cloud.

For more design information, please refer to the Alpha complex design documentation.

Bottleneck distance

An utility computes Bottleneck distance between 2 persistence diagrams.

For more design information, please refer to the Bottleneck distance design documentation.

Cover complex

Cover complex utilities compute Nerve or the Voronoi Graph Induced Complex.

For more design information, please refer to the Cover complex design documentation.

Cubical Complex

Cubical complex utilities compute Cubical (periodic or non-periodic) complex persistence from a Perseus file style.

For more design information, please refer to the Cubical complex design documentation.

Rips Complex

Rips complex utilities compute Rips complex persistence from a point cloud and a distance function, or from a distance matrix.

For more design information, please refer to the Rips complex design documentation.

Witness complex

Witness complex utilities compute Witness complex persistence from a point cloud. A weak and a strong version are available.

For more design information, please refer to the Witness complex design documentation.

Miscellaneous

An OFF point set generator utility is also available.
