Braidlab: A Software Package for Braids and Loops

Understand

Braidlab is a Matlab package for analyzing data using braids.

• It was designed to be fast, so it can be used on relatively large problems.
• It uses the object-oriented features of Matlab to provide a class for braids on punctured disks and a class for equivalence classes of simple closed loops.
• The growth of loops under iterated action by braids is used to compute the topological entropy of braids, as well as for determining the equality of braids.
