Returns whether supplied simplices exist in the complex.
find(st, simplices)a simplex tree.
simplices to insert, either as a vector, a list of vectors, or a column-matrix. See details.
boolean indicating whether or not simplex exists in the tree.
st
Traverses the simplex tree looking for simplex, returning whether or not it exists.
simplex can be specified as vector to represent a single simplex, and a list to represent a set of simplices.
Each simplex is sorted before traversing the trie.
If simplices is a vector, it's assumed to be a simplex. If a list, its assumed each element in the list
represents a simplex (as vectors). If the simplices to insert are all of the same dimension, you can also
optionally use a matrix, where each column is assumed to be a simplex.
