coface_roots: Generates a coface roots traversal on the simplex tree.

In simplextree: Provides Tools for Working with General Simplicial Complexes

Description

The coface roots of a given simplex sigma are the roots of subtrees in the trie whose descendents (including the roots themselves) are cofaces of sigma. This traversal is more useful when used in conjunction with other traversals, e.g. a preorder or level_order traversal at the roots enumerates the cofaces of sigma.

Usage

coface_roots(st, sigma)

Arguments

st	the simplex tree to traverse.
sigma	simplex to start the traversal at.
