Module lophat::utils

Utility functions and structs, including persistence diagrams and matrix anti-transposition.

Structs

• DecompositionFileFormat
  A struct which represents the output of an R=DV decomposition in a standardised format. The struct can be serialized and deserialized, and hence written to file.
• PersistenceDiagram
  Stores the pairings from a matrix decomposition, as well as those columns which did not appear in a pairing.

Functions

• anti_transpose
  Anti-transposes the input matrix (e.g. to compute cohomology).
• clone_to_file_format
  Converts the provided algorithm output to DecompositionFileFormat, making a copy in memory.
• clone_to_veccolumn
  Clones the column, converting it to VecColumn format. Under the hood, calls [col.entries()] to populate the output.
• serialize_algo
  After serializing your decomposition, you should deserialize to DecompositionFileFormat.
